CHAPTER 1
Getting Started
1.1 About Your BM2022
The BM2022 allows you to access the Internet by connecting to a WiMAX wireless network. You can
use a traditional analog telephone to make Internet calls using the BM2022s Voice over IP (VoIP)
communication capabilities.
Additionally, The web browser-based Graphical User Interface (GUI), also known as the web
configurator, provides easy management of the device and its features.
See Chapter 14 on page 199 for a complete list of features for your model.
1.1.1 WiMAX Internet Access
Connect your computer or network to the BM2022 for WiMAX Internet access. See the Quick Start
Guide for instructions on hardware connection.
In a wireless metropolitan area network (MAN), the BM2022 connects to a WiMAX base station (BS)
for Internet access.
The following diagram shows a notebook computer equipped with the BM2022 connecting to the
Internet through a WiMAX base station (marked BS).
Figure 1 Mobile Station and Base Station
When the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is
initiated from your network.
Use content filtering to block access to web sites with URLs containing keywords that you specify.
You can define time periods and days during which content filtering is enabled and include or
exclude particular computers on your network from content filtering. For example, you could block
access to certain web sites for the kids.

1.3 Good Habits for Managing the BM2022
Do the following things regularly to make the BM2022 more secure and to manage the BM2022
more effectively.
Change the password. Use a password thats not easy to guess and that consists of different
types of characters, such as numbers and letters.
Write down the password and put it in a safe place.
Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the BM2022 becomes unstable or even crashes. If you
forget your password, you will have to reset the BM2022 to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the BM2022.
You could simply restore your last configuration.
Voice Off No SIP account is registered, or the BM2022 is not receiving
power.
Green A SIP account is registered.
Green (Blinking) A SIP account is registered, and the phone attached to the
VoIP port is in use (off the hook).

Chapter 4 Tutorials
BM2022 Users Guide
44
changes dynamically. Dynamic DNS (DDNS) allows you to access the BM2022 using a domain
name.
To use this feature, you have to apply for DDNS service at www.dyndns.org.
This tutorial covers:
Registering a DDNS Account on www.dyndns.org
Configuring DDNS on Your BM2022
Testing the DDNS Setting
Note: If you have a private WAN IP address (see Private IP Addresses on page 250), then
you cannot use DDNS.

4.9 Configuring Static Route for Routing to Another
Network
In order to extend your Intranet and control traffic flowing directions, you may connect a router to
the BM2022s LAN. The router may be used to separate two department networks. This tutorial
shows how to configure a static routing rule for two network routings.
In the following figure, router R is connected to the BM2022s LAN. R connects to two networks, N1
(192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from computer A (in N1
Chapter 4 Tutorials
BM2022 Users Guide
46
network) to computer B (in N2 network), the traffic is sent to the BM2022s WAN default gateway
by default. In this case, computer B will never receive the traffic.
You need to specify a static routing rule on the BM2022 to specify R as the router in charge of
forwarding traffic to N2. In this case, the BM2022 routes traffic from computer A to R and then R
routes the traffic to computer B.
This tutorial uses the following example IP settings:
DEVICE / COMPUTER IP ADDRESS
The BM2022s WAN 172.16.1.1
The BM2022s LAN 192.168.1.1
A192.168.1.34
Rs IP address on N1 192.168.1.253
Rs IP address on N2 192.168.10.2

Chapter 4 Tutorials
BM2022 Users Guide 47
To configure a static route to route traffic from N1 to N2:
1Click Network Setting > Route > Static Route.
2Click Add to create a new route.
3Configure the Edit Static Route screen using the following settings:
3a Enter 192.168.10.0 and subnet mask 255.255.255.0 for the destination, N2.
3b Enter 192.168.1.253 (Rs IP address on N1) in the IP Address field under Next Hop.
3a Click Save.
Now computer B should be able to receive traffic from computer A. You may need to additionally
configure Rs firewall settings to accept specific traffic to pass through.
4.10 Remotely Managing Your BM2022

2Next, configure the Name, VID and Ports for the Filter Setting. Interfaces LAN1 and WiMAX
are Trunk links. On the WiMAX interface, the BM2022 will recognize VLAN 5 tagged packets it
receives from the VLAN supporting switch. VLAN tagged packets will also be forwarded out of this
interface. On the LAN1 interface, the BM2022 will tag packets it receives so that they are
recognized in VLAN 5. On LAN1, tagged packets will be untagged when they are forwarded out
since PC A does not support VLAN tagged packets. Interface IAD is configured as an Access port,
so tagged packets will be untagged when they are forwarded.
4.11.5 Scenario 5
In this scenario, PC A is directly connected to interface LAN1 on the BM2022. PC B is on VLAN 5
while PC C is on VLAN 10. PC B is connected to interface WiMAX and interface IAD for managing
the BM2022, through VLAN supporting switch S1. PC C is connected to interface WiMAX through
VLAN supporting switch S1.
Note: You will need to configure the VLAN supporting switches to tag the received packets
with the appropriate VLAN IDs. For example, packets received on switch S1 from
PC C on the LAN would be tagged to VLAN 10.

CHAPTER 6
WiMAX
6.1 Overview
This chapter shows you how to set up and manage the connection between the BM2022 and your
ISPs base stations.
6.1.1 What You Need to Know
The following terms and concepts may help as you read through this chapter.
WiMAX
WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 wireless networking
standard, which provides high-bandwidth, wide-range wireless service across wireless Metropolitan
Area Networks (MANs). Huawei is a member of the WiMAX Forum, the industry group dedicated to
promoting and certifying interoperability of wireless broadband products.
In a wireless MAN, a wireless-equipped computer is known either as a mobile station (MS) or a
subscriber station (SS). Mobile stations use the IEEE 802.16e standard and are able to maintain
connectivity while switching their connection from one base station to another base station
(handover) while subscriber stations use other standards that do not have this capability (IEEE
802.16-2004, for example). The following figure shows an MS-equipped notebook computer MS1
moving from base station BS1s coverage area and connecting to BS2.
Figure 15 WiMax: Mobile Station
Chapter 6 WiMAX
BM2022 Users Guide
66
WiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber stations and
mobile stations to local base stations. Numerous subscriber stations and mobile stations connect to
the network through a single base station (BS), as in the following figure.
Figure 16 WiMAX: Multiple Mobile Stations
A base stations coverage area can extend over many hundreds of meters, even under poor
conditions. A base station provides network access to subscriber stations and mobile stations, and
communicates with other base stations.
The radio frequency and bandwidth of the link between the BM2022 and the base station are
controlled by the base station. The BM2022 follows the base stations configuration.
Authentication
When authenticating a user, the base station uses a third-party RADIUS or Diameter server known
as an AAA (Authentication, Authorization and Accounting) server to authenticate the mobile or
subscriber stations.
The following figure shows a base station using an AAA server to authenticate mobile station MS,
allowing it to access the Internet.
Figure 17 Using an AAA Server
In this figure, the dashed arrow shows the PKM (Privacy Key Management) secured connection
between the mobile station and the base station, and the solid arrow shows the EAP secured
connection between the mobile station, the base station and the AAA server. See the WiMAX
security appendix for more details.
Chapter 6 WiMAX
BM2022 Users Guide 67
Frequency Ranges
The following figure shows the BM2022 searching a range of frequencies to find a connection to a
base station.
Figure 18 Frequency Ranges
In this figure, A is the WiMAX frequency range. WiMAX frequency range refers to the entire range
of frequencies the BM2022 is capable of using to transmit and receive (see the Product
Specifications appendix for details).
In the figure, B shows the operator frequency range. This is the range of frequencies within the
WiMAX frequency range supported by your operator (service provider).
The operator range is subdivided into bandwidth steps. In the figure, each C is a bandwidth step.
The arrow D shows the BM2022 searching for a connection.
Have the BM2022 search only certain frequencies by configuring the downlink frequencies. Your
operator can give you information on the supported frequencies.
The downlink frequencies are points of the frequency range your BM2022 searches for an available
connection. Use the Site Survey screen to set these bands. You can set the downlink frequencies
anywhere within the WiMAX frequency range. In this example, the downlink frequencies have been
set to search all of the operator range for a connection.
Certification Authority
A Certification Authority (CA) issues certificates and guarantees the identity of each certificate
owner. There are commercial certification authorities like CyberTrust or VeriSign and government
certification authorities. You can use the BM2022 to generate certification requests that contain
identifying information and public keys and then send the certification requests to a certification
authority.
Certificate File Formats
The certification authority certificate that you want to import has to be in one of these file formats:
Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters,
uppercase letters and numerals to convert a binary X.509 certificate into a printable form.
Binary PKCS#7: This is a standard that defines the general syntax for data (including digital
signatures) that may be encrypted. The BM2022 currently allows the importation of a PKS#7 file
that contains a single certificate.
Chapter 6 WiMAX
BM2022 Users Guide
68
PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses 64 ASCII
characters to convert a binary PKCS#7 certificate into a printable form.
CINR
Carrier to Interference-plus-Noise Ratio (CINR) measures the effectiveness of a wireless signal and
plays an important role in allowing the BM2022 to decode signal burst. If a burst has a high signal
strength and a high interference-plus-noise ratio, it can use Digital Signal Processing (DSP) to
decode it; if the signal strength is lower, it can switch to an alternate burst profile.
RSSI
Received Signal Strength Indicator (RSSI) measures the relative strength of a given wireless signal.
This is important in determining if a signal is below the Clear-To-Send (CTS) threshold. If it is below
the arbitrarily specified threshold, then BM2022 is free to transmit any data packets.
EAP Authentication
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE
802.1x transport mechanism in order to support multiple types of user authentication. By using EAP
to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a
RADIUS server perform authentication.
The BM2022 supports EAP-TLS and EAP-TTLS (at the time of writing, TTLS is not available in
Windows Vista). For EAP-TLS authentication type, you must first have a wired connection to the
network and obtain the certificate(s) from a certificate authority (CA). Certificates (also called
digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the
identity of each certificate owner.

EAP Supplicant
EAP Mode Select an Extensible Authentication Protocol (EAP) mode.
The BM2022 supports the following:
EAP-TLS - In this protocol, digital certifications are needed by both the
server and the wireless clients for mutual authentication. The server presents
a certificate to the client. After validating the identity of the server, the client
sends a different certificate to the server. The exchange of certificates is done
in the open before a secured tunnel is created. This makes user identity
vulnerable to passive attacks. A digital certificate is an electronic ID card that
authenticates the senders identity. However, to implement EAP-TLS, you
need a Certificate Authority (CA) to handle certificates, which imposes a
management overhead.
EAP-TTLS - This protocol is an extension of the EAP-TLS authentication that
uses certificates for only the server-side authentications to establish a secure
connection. Client authentication is then done by sending username and
password through the secure connection, thus client identity is protected. For
client authentication, EAP-TTLS supports EAP methods and legacy
authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2.

BM2022 will scan for base stations that are operated by Network Access Providers (NAP) that have
service agreements with the subscribers service provider (Home-Network Service Provider or
Inner Mode Sets the EAP-TTLS inner mode.
The BM2022 supports the following:
MS-CHAP v2 - This is version 2 of Microsofts variant of Challenge
Handshake Authentication Protocol (CHAP). It allows for mutual
authentication between devices.
MS-CHAP - This is Microsofts variant of Challenge Handshake
Authentication Protocol (CHAP). It allows for mutual authentication between
devices.
CHAP - The Challenge Handshake Authentication Protocol (CHAP) uses PPP
to authenticate remote devices using a three-way handshake and shared
secret verification.
MD5 - Message-Digest, algorithm 5, (MD5) encryption is typically used for
checking file integrity. Because this encryption protocol contains a number of
serious security flaws it is generally not recommended that you use it for
authentication security.
PAP - Password Authentication Protocol uses unencrypted plaintext to send a
passwords for authentication over the network. Its probably not a good idea
to rely on this for security.

BM2022 can access the Internet through a network service provider (NSP). Access can be through
another network service provider (Visited-Network Service Provider or V-NSP) or his own network
service provider (Home NSP), depending on his service agreement.
In the following scenario, the subscribers BM2022 cannot reach a base station owned by his Home
NSP (base station with NAP-ID = 1). The BM2022 uses ND&S and is able to access another base
station with NAP-ID = 2. This base station is associated with another service provider (V-NSP with
NSP-ID = 20). The subscribers service agreement specifies to route traffic from the other service
provider to the Home NSP, so the Home NSP authenticates and authorizes the connection.

CHAPTER 7
Network Setting
7.1 Overview
This chapter shows you how to configure the BM2022s network setting.
7.1.1 What You Need to Know
The following terms and concepts may help as you read through this chapter.
IP Address
IP addresses identify individual devices on a network. Every networking device (including
computers, servers, routers, printers, etc.) needs an IP address to communicate across the
network. These networking devices are also known as hosts.
Subnet Masks
Subnet masks determine the maximum number of possible hosts on a network. You can also use
subnet masks to divide one network into multiple sub-networks.
DHCP
A DHCP (Dynamic Host Configuration Protocol) server can assign your BM2022 an IP address,
subnet mask, DNS and other routing information when its turned on.
DNS Server Address
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and
vice versa. The DNS server is extremely important because without it, you must know the IP
address of a machine before you can access it. The DNS server addresses that you enter in the
DHCP setup are passed to the client machines along with the assigned IP address and subnet mask.
There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to
tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he
signs up. If your ISP gives you the DNS server addresses, enter them in the DNS Server fields;
otherwise, leave them blank.
Some ISPs choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control
Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are
the DNS servers are conveyed through IPCP negotiation. The BM2022 supports the IPCP DNS
server extensions through the DNS proxy feature.
Chapter 7 Network Setting
BM2022 Users Guide
92
If the Primary and Secondary DNS Server fields are not specified, for instance, left as 0.0.0.0,
the BM2022 tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS
query to the BM2022, the BM2022 forwards the query to the real DNS server learned through IPCP
and relays the response back to the computer.
Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does
not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP
gives you explicit DNS servers, make sure that you enter their IP addresses. This way, the BM2022
can pass the DNS servers to the computers and the computers can query the DNS server directly
without the BM2022s intervention.
RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction field controls the sending and receiving of RIP packets. When set to:
RX/TX - the BM2022 will broadcast its routing table periodically and incorporate the RIP
information that it receives.
RX Only - the BM2022 will not send any RIP packets but will accept all RIP packets received.
TX Only - the BM2022 will send out RIP packets but will not accept any RIP packets received.
None - the BM2022 will not send any RIP packets and will ignore any RIP packets received.
The Version field controls the format and the broadcasting method of the RIP packets that the
BM2022 sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-
2 carries more information. RIP-1 is probably adequate for most networks, unless you have an
unusual network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B
uses subnet broadcasting while RIP-2M uses multicasting.
Port Forwarding
A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that
you can make accessible to the outside world even though NAT makes your whole inside network
appear as a single machine to the outside world.
With port forwarding, you can forward incoming service requests to the server(s) on your local
network. You may enter a single port number or a range of port numbers to be forwarded, and the
local IP address of the desired server. The port number identifies a service; for example, web
service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one
server can support more than one service (for example both FTP and web service), it might be
better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request
that does not have a server explicitly designated for it is forwarded to the default server. If the
default is not defined, the service request is simply discarded.
For example, let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the
example), port 80 to another (B in the example) and assign a default server IP address of
Chapter 7 Network Setting
BM2022 Users Guide 93
192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns
the WAN IP address. The NAT network appears as a single host on the Internet.
Figure 35 Multiple Servers Behind NAT Example
Trigger Ports
Some services use a dedicated range of ports on the client side and a dedicated range of ports on
the server side. With regular port forwarding you set a forwarding port in NAT to forward a service
(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN).
The problem is that port forwarding only forwards a service to a single LAN IP address. In order to
use the same service on a different LAN computer, you have to manually replace the LAN
computer's IP address in the forwarding port with another LAN computer's IP address,
Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take
turns using the service. The BM2022 records the IP address of a LAN computer that sends traffic to
the WAN to request a service with a specific port number and protocol (a "trigger" port). When the
BM2022's WAN port receives a response with a specific port number and protocol ("incoming" port),
the BM2022 forwards the traffic to the LAN IP address of the computer that sent the request. After
that computers connection for that service closes, another computer on the LAN can use the
service in the same manner. This way you do not need to configure a new IP address each time you
want a different LAN computer to use the application.
ALG
Some applications, such as SIP, cannot operate through NAT (are NAT un-friendly) because they
embed IP addresses and port numbers in their packets data payload. Some NAT routers may
include a SIP Application Layer Gateway (ALG). An Application Layer Gateway (ALG) manages a
specific protocol (such as SIP, H.323 or FTP) at the application layer.
A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses
embedded in the data stream.
UPnP
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
How do I know if I'm using UPnP?
Chapter 7 Network Setting
BM2022 Users Guide
94
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP
compatible device installed on your network will appear as a separate icon. Selecting the icon of a
UPnP device will allow you to access the information and properties of that device.
NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP
network devices can automatically configure network addressing, announce their presence in the
network to other UPnP devices and enable exchange of simple product and service descriptions.
NAT traversal allows the following:
Dynamic port mapping
Learning public IP addresses
Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal and UPnP.
Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configuration may also
be obtained and modified by users in some network environments.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.
UPnP and Huawei
Huawei has received UPnP certification from the official UPnP Forum (http://www.upnp.org).
Huawei's UPnP implementation supports IGD 1.0 (Internet Gateway Device).
The BM2022 only sends UPnP multicasts to the LAN.
Content Filter
Internet content filtering allows you to create and enforce Internet access policies tailored to their
needs. Content filtering is the ability to block certain specific URL keywords.

7.12.2 Trigger Port Forwarding Example
The following is an example of trigger port forwarding. In this example, J is Janes computer and S
is the Real Audio server.
Figure 49 Trigger Port Forwarding Example
1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a trigger port and causes the BM2022 to record Janes computer IP address. The
BM2022 associates Jane's computer IP address with the "incoming" port range of 6970-7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The BM2022 forwards the traffic to Janes computer IP address.
5Only Jane can connect to the Real Audio server until the connection is closed or times out. The
BM2022 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP
(Transfer Control Protocol/Internet Protocol).
Two points to remember about trigger ports:
1Trigger events only happen on data that is coming from inside the BM2022 and going to the
outside.
2If an application needs a continuous data stream, that port (range) will be tied up so that another
computer on the LAN cant trigger it.

This chapter shows you how to configure the BM2022s network settings.
8.1.1 What You Need to Know
The following terms and concepts may help as you read through this chapter.
About the BM2022s Security Features
The BM2022 security features are designed to protect against Denial of Service attacks when
activated as well as block access to and from specific URLs and MAC addresses. Its purpose is to
allow a private Local Area Network (LAN) to be securely connected to the Internet. The BM2022 can
be used to prevent theft, destruction and modification of data.
The BM2022 is installed between the LAN and a WiMAX base station connecting to the Internet.
This allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The BM2022 has one Ethernet (LAN) port. The LAN (Local Area Network) port attaches to a network
of computers, which needs security from the outside world. These computers will have access to
Internet services such as e-mail, FTP and the World Wide Web. However, inbound access is not
allowed (by default) unless the remote host is authorized to use a specific service.

SYN Flood
Select this to monitor for and block TCP SYN flood attacks.
A SYN flood is one type of denial of service attack where an overwhelming
number of SYN requests assault a client device.
Prevent from UDP
Flood
Select this to monitor for and block UDP flood attacks.
An UDP flood is a type of denial of service attack where an overwhelming
number of UDP packets assault random ports on a client device. Because the
device is forced to analyze and respond to each packet, it quickly becomes
unreachable to other devices.
Prevent from
ICMP Flood
Select this to monitor for and block ICMP flood attacks.
An ICMP flood is a type of denial of service attack where an overwhelming
number of ICMP ping assault a client device, locking it down and preventing it
from responding to requests from other servers.
Prevent from Port
Scan
Select this to monitor for and block port scan attacks.
A port scan attack is typically the precursor to a full-blown denial of service
attack wherein each port on a device is probed for security holes that can be
exploited. Once a security flaw is discovered, an attacker can initiate the
appropriate denial of service attack or intrusion attack against the client device.
Prevent from
LAND Attack
Select this to monitor for and block LAND attacks.
A Local Area Network Denial (LAND) attack is a type of denial of service attack
where a spoofed TCP SYN packet targets a client devices IP address and forces it
into an infinite recursive loop of querying itself and then replying, effectively
locking it down.
Prevent from IP
Spoof
Select this to monitor for and block IP address spoof attacks.
An IP address spoof is an attack whereby the source IP address in the incoming
IP packets allows a malicious party to masquerade as a legitimate user and gain
access to the client device.
Prevent from
ICMP redirect
Select this to monitor for and block ICMP redirect attacks.
An ICMP redirect attack is one where forged ICMP redirect messages can force
the client device to route packets for certain connections through an attackers

8.12.1 IPSec Architecture
The overall IPSec architecture is shown as follows.
Figure 70 IPSec Architecture
IPSec Algorithms
The ESP (Encapsulating Security Payload) Protocol (RFC 2406) and AH (Authentication Header)
protocol (RFC 2402) describe the packet formats and the default standards for packet structure
(including implementation algorithms).
The Encryption Algorithm describes the use of encryption techniques such as DES (Data Encryption
Standard) and Triple DES algorithms.

PFS changes the root key that is used to generate encryption keys for each IPSec
SA. The longer the key, the more secure the encryption, but also the longer it
takes to encrypt and decrypt information. Both routers must use the same DH
key group.

Table 56 IPSec VPN: Add
LABEL DESCRIPTION
Chapter 8 Security
BM2022 Users Guide 141
The Authentication Algorithms, HMAC-MD5 (RFC 2403) and HMAC-SHA-1 (RFC 2404, provide an
authentication mechanism for the AH and ESP protocols.
Key Management
Key management allows you to determine whether to use IKE (ISAKMP) or manual key
configuration in order to set up a VPN.
8.12.2 Encapsulation
The two modes of operation for IPSec VPNs are Transport mode and Tunnel mode. At the time of
writing, the BM2022 supports Tunnel mode only.
Figure 71 Transport and Tunnel Mode IPSec Encapsulation
Transport Mode
Transport mode is used to protect upper layer protocols and only affects the data in the IP packet.
In Transport mode, the IP packet contains the security protocol (AH or ESP) located after the
original IP header and options, but before any upper layer protocols contained in the packet (such
as TCP and UDP).
With ESP, protection is applied only to the upper layer protocols contained in the packet. The IP
header information and options are not used in the authentication process. Therefore, the
originating IP address cannot be verified for integrity against the data.
With the use of AH as the security protocol, protection is extended forward into the IP header to
verify the integrity of the entire packet by use of portions of the original IP header in the hashing
process.
Tunnel Mode
Tunnel mode encapsulates the entire IP packet to transmit it securely. A Tunnel mode is required
for gateway services to provide access to internal systems. Tunnel mode is fundamentally an IP
tunnel with authentication and encryption. This is the most common mode of operation. Tunnel
mode is required for gateway to gateway and host to gateway communications. Tunnel mode
communications have two sets of IP headers:
Outside header: The outside IP header contains the destination IP address of the VPN gateway.
Chapter 8 Security
BM2022 Users Guide
142
Inside header: The inside IP header contains the destination IP address of the final system
behind the VPN gateway. The security protocol appears after the outer IP header and before the
inside IP header.
8.12.3 IKE Phases
There are two phases to every IKE (Internet Key Exchange) negotiation phase 1 (Authentication)
and phase 2 (Key Exchange). A phase 1 exchange establishes an IKE SA and the second one uses
that SA to negotiate SAs for IPSec.
Figure 72 Two Phases to Set Up the IPSec SA
In phase 1 you must:
Choose a negotiation mode.
Authenticate the connection by entering a pre-shared key.
Choose an encryption algorithm.
Choose an authentication algorithm.
Choose a Diffie-Hellman public-key cryptography key group (DH1 or DH2).
Set the IKE SA lifetime. This field allows you to determine how long an IKE SA should stay up
before it times out. An IKE SA times out when the IKE SA lifetime period expires. If an IKE SA
times out when an IPSec SA is already established, the IPSec SA stays connected.
In phase 2 you must:

Set the IPSec SA lifetime. This field allows you to determine how long the IPSec SA should stay
up before it times out. The BM2022 automatically renegotiates the IPSec SA if there is traffic
when the IPSec SA lifetime period expires. If an IPSec SA times out, then the IPSec router must
renegotiate the SA the next time someone attempts to send traffic.

8.12.4 Negotiation Mode
The phase 1 Negotiation Mode you select determines how the Security Association (SA) will be
established for each connection through IKE negotiations.
Main Mode ensures the highest level of security when the communicating parties are
negotiating authentication (phase 1). It uses 6 messages in three round trips: SA negotiation,
Diffie-Hellman exchange and an exchange of nonces (a nonce is a random number). This mode
features identity protection (your identity is not revealed in the negotiation).
Aggressive Mode is quicker than Main Mode because it eliminates several steps when the
communicating parties are negotiating authentication (phase 1). However the trade-off is that
faster speed limits its negotiating power and it also does not provide identity protection. It is
useful in remote access situations where the address of the initiator is not know by the responder
and both parties want to use pre-shared key authentication.
8.12.5 IPSec and NAT
Read this section if you are running IPSec on a host computer behind the BM2022.
NAT is incompatible with the AH protocol in both Transport and Tunnel mode. An IPSec VPN using
the AH protocol digitally signs the outbound packet, both data payload and headers, with a hash
value appended to the packet. When using AH protocol, packet contents (the data payload) are not
encrypted.
A NAT device in between the IPSec endpoints will rewrite either the source or destination address
with one of its own choosing. The VPN device at the receiving end will verify the integrity of the
incoming packet by computing its own hash value, and complain that the hash value appended to
the received packet doesn't match. The VPN device at the receiving end doesn't know about the
NAT in the middle, so it assumes that the data has been maliciously altered.
IPSec using ESP in Tunnel mode encapsulates the entire original packet (including headers) in a
new IP packet. The new IP packet's source address is the outbound address of the sending VPN
gateway, and its destination address is the inbound address of the VPN device at the receiving end.
When using ESP protocol with authentication, the packet contents (in this case, the entire original
packet) are encrypted. The encrypted contents, but not the new headers, are signed with a hash
value appended to the packet.
Tunnel mode ESP with authentication is compatible with NAT because integrity checks are
performed over the combination of the "original header plus original payload," which is unchanged
by a NAT device.
Transport mode ESP with authentication is not compatible with NAT.

8.12.6 VPN, NAT, and NAT Traversal
NAT is incompatible with the AH protocol in both transport and tunnel mode. An IPSec VPN using
the AH protocol digitally signs the outbound packet, both data payload and headers, with a hash
value appended to the packet, but a NAT device between the IPSec endpoints rewrites the source or
destination address. As a result, the VPN device at the receiving end finds a mismatch between the
hash value and the data and assumes that the data has been maliciously altered.
NAT is not normally compatible with ESP in transport mode either, but the BM2022s NAT
Traversal feature provides a way to handle this. NAT traversal allows you to set up an IKE SA when
there are NAT routers between the two IPSec routers.
Figure 73 NAT Router Between IPSec Routers
Normally you cannot set up an IKE SA with a NAT router between the two IPSec routers because
the NAT router changes the header of the IPSec packet. NAT traversal solves the problem by adding
a UDP port 500 header to the IPSec packet. The NAT router forwards the IPSec packet with the UDP
port 500 header unchanged. In the above figure, when IPSec router A tries to establish an IKE SA,
IPSec router B checks the UDP port 500 header, and IPSec routers A and B build the IKE SA.
For NAT traversal to work, you must:
Use ESP security protocol (in either transport or tunnel mode).
Use IKE keying mode.
Enable NAT traversal on both IPSec endpoints.
Set the NAT router to forward UDP port 500 to IPSec router A.
Finally, NAT is compatible with ESP in tunnel mode because integrity checks are performed over the
combination of the "original header plus original payload," which is unchanged by a NAT device. The
compatibility of AH and ESP with NAT in tunnel and transport modes is summarized in the following
table.
Y* - This is supported in the BM2022 if you enable NAT traversal.
8.12.7 ID Type and Content
With aggressive negotiation mode (see Section 8.12.4 on page 143), the BM2022 identifies
incoming SAs by ID type and content since this identifying information is not encrypted. This
Table 58 VPN and NAT
SECURITY PROTOCOL MODE NAT

Chapter 8 Security
BM2022 Users Guide 145
enables the BM2022 to distinguish between multiple rules for SAs that connect from remote IPSec
routers that have dynamic WAN IP addresses.
Regardless of the ID type and content configuration, the BM2022 does not allow you to save
multiple active rules with overlapping local and remote IP addresses.
With main mode (see Section 8.12.4 on page 143), the ID type and content are encrypted to
provide identity protection. In this case the BM2022 can only distinguish between up to 12 different
incoming SAs that connect from remote IPSec routers that have dynamic WAN IP addresses. The
BM2022 can distinguish up to 48 incoming SAs because you can select between three encryption
algorithms (DES, 3DES and AES), two authentication algorithms (MD5 and SHA1) and eight key
groups when you configure a VPN rule (see Section 8.11.1 on page 133). The ID type and content
act as an extra level of identification for incoming SAs.
The type of ID can be a domain name, an IP address or an e-mail address. The content is the IP
address, domain name, or e-mail address.
8.12.7.1 ID Type and Content Examples
Two IPSec routers must have matching ID type and content configuration in order to set up a VPN
tunnel.
The two BM2022s in this example can complete negotiation and establish a VPN tunnel.
The two BM2022s in this example cannot complete their negotiation because BM2022 Bs Local ID
type is IP, but BM2022 As Remote ID type is set to E-mail. An ID mismatched message
displays in the IPSEC LOG.

DNS Type a domain name (up to 31 characters) by which to identify this BM2022.

8.12.8 Pre-Shared Key
A pre-shared key identifies a communicating party during a phase 1 IKE negotiation (see Section
8.12.3 on page 142 for more on IKE phases). It is called pre-shared because you have to share it
with another party before you can communicate with them over a secure connection.
8.12.9 Diffie-Hellman (DH) Key Groups
Diffie-Hellman (DH) is a public-key cryptography protocol that allows two parties to establish a
shared secret over an unsecured communications channel. Diffie-Hellman is used within IKE SA
setup to establish session keys. 768-bit, 1024-bit 1536-bit, 2048-bit, and 3072-bit Diffie-Hellman
groups are supported. Upon completion of the Diffie-Hellman exchange, the two peers have a
shared secret, but the IKE SA is not authenticated. For authentication, use pre-shared keys.

CHAPTER 9
The VoIP General Screens
9.1 VoIP Overview
The VOICE > General screens allow you to set up global SIP and Quality of Service (QoS) settings.
VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you to
make phone calls and send faxes over the Internet at a fraction of the cost of using the traditional
circuit-switched telephone network. You can also use servers to run telephone service applications
like PBX services and voice mail. Internet Telephony Service Provider (ITSP) companies provide
VoIP service. A company could alternatively set up an IP-PBX and provide its own VoIP service.
Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to
handle a telephone call. VoIP can use advanced voice coding techniques with compression to reduce
the required bandwidth.
9.1.1 What You Can Do in This Chapter
The Media screen (Section 9.2 on page 149) lets you set up and maintain global VoIP settings on
the BM2022.
The QoS screen (Section 9.3 on page 150) lets you set up and maintain QoS settings for voice
traffic flowing through the BM2022.
The SIP screen (Section 9.4 on page 151) lets you enable session timer and select the SIP
session refresh method.
The Speed Dial screen (Section 9.5 on page 151) lets you add, edit, or remove speed-dial
entries for the phone line.
9.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Voice Coding
A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital
signals back into voice signals. The BM2022 supports the following codecs.
G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures analog signal
amplitudes at regular time intervals (sampling) and converts them into digital bits (quantization).
Quantization reads the analog signal and then writes it to the nearest digital value. For this
reason, a digital sample is usually slightly different from its analog original (this difference is
known as quantization noise). G.711 provides excellent sound quality but requires 64kbps of
bandwidth.
Chapter 9 The VoIP General Screens
BM2022 Users Guide
148
G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec. It uses a filter based on
information about how the human vocal tract produces sounds. The codec analyzes the incoming
voice signal and attempts to synthesize it using its list of voice elements. It tests the synthesized
signal against the original and, if it is acceptable, transmits details of the voice elements it used
to make the synthesis. Because the codec at the receiving end has the same list, it can exactly
recreate the synthesized audio signal.G.729 provides good sound quality and reduces the
required bandwidth to 8kbps.
Quality of Service (QoS)
Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay and
the networking methods used to provide bandwidth for real-time multimedia applications.
Type Of Service (ToS)
Network traffic can be classified by setting the ToS (Type Of Service) values at the data source (for
example, at the BM2022) so a server can decide the best method of delivery, that is the least cost,
fastest route and so on. The ToS field is consist of 8 bits. The first 3 bits indicate the priority of the
packet.
DiffServ
DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-hop
treatment at DiffServ-compliant network devices along the route based on the application types
and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the level of
service desired. This allows the intermediary DiffServ-compliant network devices to handle the
packets differently depending on the code points without the need to negotiate paths or remember
state information for every flow. In addition, applications do not have to request a particular service
or give advanced notice of where the traffic is going.
DiffServ uses the first 6 bits of the 8-bit ToS value so that it can be backward compatible with non-
DiffServ compliant but ToS-enabled network device. See Section 9.6.1 on page 152 for more
information.
SIP
The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles
the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP
signaling is separate from the media for which it handles sessions. The media that is exchanged
during the session can use a different path from that of the signaling. SIP handles telephone calls
and can interface with traditional circuit-switched telephone networks.
RTP
When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to handle voice
data transfer. See RFC 1889 for details on RTP.
Speed Dial
Speed dial provides shortcuts for dialing frequently used phone numbers. You can map a phone
number to a self-defined key(s) and then use that key(s) to call the phone number. For example,
you can map 123456 to #01. When you press #01 it means that you press 123456.

The following table describes the labels in this screen.
Voice Jitter Buffer
Type
Voice jitter is a variation in delay of RTP packets delivery. This could cause
strange sound effects. The BM2022 can utilize the following types of jitter buffer
to minimize the effects of jitter.
Dynamic - Jitter buffer size is dynamically changed by RTP packets delivery
status.
Static - Jitter buffer size is fixed.
Voice Jitter Buffer
Length
Select the maximum number of milliseconds of voice traffic the BM2022 can help
to smooth out the jitter in order to ensure good voice quality for your

SIP ToS/DiffServ Enter the DSCP value you want to mark on all outgoing SIP packets generated by
the BM2022 for DiffServ-enabled networks. Since DiffServ uses the first 6 bits of
the 8-bit IP ToS field to represent the DSCP value, enter here the 6-bit DSCP
value you want to mark in hexadecimal (in a format of 0x00), and the BM2022
will then automatically append 2 bits '0' to make a whole 8-bit ToS field value for
all outgoing SIP packets.
For example, if you enter 0x2E, it is 101110 in binary for DSCP. The BM2022
converts it to 10111000 in binary and marks on the IP ToS field of all the
outgoing SIP packets.
RTP ToS/DiffServ Enter the DSCP value you want to mark on all outgoing VoIP data packets

The Update method uses less overhead than Re-Invite, but is not as widely
supported as Re-Invite. By default the BM2022 is set to use the UPDATE
method. When set to UPDATE, the BM2022 can also revert to using the
INVITE method for SIP session refresh, depending on the method supported
and allowed by the peer device.

9.6 Technical Reference
The following section contains additional technical information about the BM2022 features
described in this chapter.
9.6.1 DSCP and Per-Hop Behavior
DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service (TOS) field
in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define
up to 64 service levels. The following figure illustrates the DS field.
Figure 78 DiffServ: Differentiated Service Field
DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ
compliant, ToS-enabled network device will not conflict with the DSCP mapping.
The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet
gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be
marked for different priorities of forwarding. Resources can then be allocated according to the DSCP
values and the configured policies.

10.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
SIP Identities
A SIP account uses an identity (sometimes referred to as a SIP address). A complete SIP identity is
called a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the SIP account in a
way similar to the way an e-mail address identifies an e-mail account. The format of a SIP identity
is SIP-Number@SIP-Service-Domain.
SIP Number
The SIP number is the part of the SIP URI that comes before the @ symbol. A SIP number can
use letters like in an e-mail address (johndoe@your-ITSP.com for example) or numbers like a
telephone number (1122334455@VoIP-provider.com for example).
Chapter 10 The VoIP Account Screens
BM2022 Users Guide
154
SIP Service Domain
The SIP service domain of the VoIP service provider (the company that lets you make phone calls
over the Internet) is the domain name in a SIP URI. For example, if the SIP address is
1122334455@VoIP-provider.com, then VoIP-provider.com is the SIP service domain.
SIP Register Server
A SIP register server maintains a database of SIP identity-to-IP address (or domain name)
mapping. The register server checks your user name and password when you register.
SIP User Agent
A SIP user agent can make and receive VoIP telephone calls. This means that SIP can be used for
peer-to-peer communications even though it is a client-server protocol. In the following figure,
either A or B can act as a SIP user agent client to initiate a call. A and B can also both act as a SIP
user agent to receive the call.
Figure 79 SIP User Agent
SIP Proxy Server
A SIP proxy server receives requests from clients and forwards them to another server.
In the following example, you want to use client device A to call someone who is using client device
C.
1The client device (A in the figure) sends a call invitation to the SIP proxy server (B).
2The SIP proxy server forwards the call invitation to C.

STUN
STUN (Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators)
allows the BM2022 to find the presence and types of NAT routers and/or firewalls between it and
the public Internet. STUN also allows the BM2022 to find the public IP address that NAT assigned,
so the BM2022 can embed it in the SIP data stream. STUN does not work with symmetric NAT
routers or firewalls. See RFC 3489 for details on STUN.
The following figure shows how STUN works.
1The BM2022 (A) sends SIP packets to the STUN server (B).
2The STUN server (B) finds the public IP address and port number that the NAT router used on the
BM2022s SIP packets and sends them to the BM2022.
3The BM2022 uses the public IP address and port number in the SIP packets that it sends to the SIP
server (C).
Figure 81 STUN
Outbound Proxy
Your VoIP service provider may host a SIP outbound proxy server to handle all of the BM2022s
VoIP traffic. This allows the BM2022 to work with any type of NAT router and eliminates the need
for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of the BM2022 to keep it from
retranslating the IP address (since this is already handled by the outbound proxy server).
NAT and SIP
The BM2022 must register its public IP address with a SIP register server. If there is a NAT router
between the BM2022 and the SIP register server, the BM2022 probably has a private IP address.
The BM2022 lists its IP address in the SIP message that it sends to the SIP register server. NAT
does not translate this IP address in the SIP message. The SIP register server gets the BM2022s IP
address from inside the SIP message and maps it to your SIP identity. If the BM2022 has a private
IP address listed in the SIP message, the SIP server cannot map it to your SIP identity.
Use a SIP ALG (Application Layer Gateway), STUN, or outbound proxy to allow the BM2022 to list
its public IP address in the SIP messages.
DTMF
Dual-Tone Multi-Frequency (DTMF) telephone call signaling uses pairs of frequencies (one lower
frequency and one higher frequency) to set up calls. It is also known as Touch Tone. Each of the
keys on a DTMF telephone corresponds to a different pair of frequencies.

Register
Period Time
Enter the registration expiry time in seconds for the SIP account specified in
Section 10.4 on page 159. The allowable range is 60~65535 seconds. However,
this value is just a default preference value by user, the actual registration expiry
time used by the SIP account is determined by the registrar server after the
registration process.
Once the SIP account has registered at the registrar server successfully, the
BM2022 will send a re-register message to keep alive the successfully registered
status at every half of the registration expiry time determined by the registrar
server.
If the keep-alive action failed, the register status described in Section 10.2 on
page 156 will become Error state and you can not make any call in this status.
However, after 512 seconds (fixed value), the BM2022 will send a register
message again to try to recover a successfully registered status.

and tell the peer to use this value as the minimum bound.
Session Timer Enter the session expiry time in seconds for all phone connections on this
trunk. The allowable range is 120~65535 seconds. This value cannot be lower
than the Min Session Timer.
The BM2022 will use INVITE or UPDATE method to keep alive a session every
half of the session expiry time during a call.
If the keep-alive action is successful, the BM2022 will re-start the timer and do
another keep-alive action after it reaches half of the session expiry time.
If the keep-alive action failed, the call will terminate automatically.

DTMF
DTMF Control how the BM2022 handles the DTMF tone relay to the communication
peer. The DTMF tone is generated by the phone when you push its digit
buttons during a call. One application is to send numbers when trying to do
IVR (Interactive Voice Response) service with server.
You should use the same mode as your VoIP service provider. The choices are:
Out-of-band(RFC 2833) - Follow the RFC 2833 standard and send the
DTMF tones in RTP packets.
In Band - Send the DTMF tones in the voice data stream. This works best
when you are using a codec that does not use compression (like G.711).

10.8.2 SIP Client Server
SIP is a client-server protocol. A SIP client is an application program or device that sends SIP
requests. A SIP server responds to the SIP requests.
When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A SIP
client could be a computer or a SIP phone. One device can act as both a SIP client and a SIP server.
For more information on the SIP protocol, please refer to RFC 3261.

The VoIP > Line screens allow you to configure the volume, echo cancellation, VAD settings and
custom tones for the phone port which maps to the SIP account (see Chapter 10 on page 153).
11.1.1 What You Can Do in This Chapter
The Phone screen (Section 11.2 on page 168) lets you configure phone settings.
The Voice screen (Section 11.3 on page 168) lets you configure voice settings.

BM2022 is in.
11.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Voice Activity Detection/Silence Suppression/Comfort Noise
Voice Activity Detection (VAD) detects whether or not speech is present. This lets the BM2022
reduce the bandwidth that a call uses by not transmitting silent packets when you are not
speaking.
When using VAD, the BM2022 generates comfort noise when the other party is not speaking. The
comfort noise lets you know that the line is still connected as total silence could easily be mistaken
for a lost connection.
Echo Cancellation
G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice
reverberating in the telephone receiver while you talk.

CHAPTER 12
Maintenance
12.1 Overview
Use these screens to manage and maintain your BM2022.
12.1.1 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Remote Management Limitations
Remote management over LAN or WAN will not work when:
1You have disabled that service in one of the remote management screens.
2The IP address in the Secured Client IP field does not match the client IP address. If it does not
match, the BM2022 will disconnect the session immediately.
3There is already another remote management session with an equal or higher priority running. You
may only have one remote management session running at one time.
Remote Management and NAT
When NAT is enabled:
Use the BM2022s WAN IP address when configuring from the WAN.
Use the BM2022s LAN IP address when configuring from the LAN.
System Timeout
There is a default system management idle timeout of five minutes. The BM2022 automatically logs
you out if the management session remains idle for longer than this timeout period. The
management session does not time out when a statistics screen is polling.
SNMP
Simple Network Management Protocol (SNMP) is a protocol used for exchanging management
information between network devices. SNMP is a member of the TCP/IP protocol suite. Your
BM2022 supports SNMP agent functionality, which allows a manager station to manage and monitor
the BM2022 through the network. The BM2022 supports SNMP version one (SNMPv1) and version
two (SNMPv2). The next figure illustrates an SNMP management operation.
Chapter 12 Maintenance
BM2022 Users Guide
172
Note: SNMP is only available if TCP/IP is configured.
TR-069
TR-069 is an abbreviation of Technical Reference 069, a protocol designed to facilitate the remote
management of Customer Premise Equipement (CPE), such as the BM2022. It can be managed
over a WAN by means of an Auto Configuration Server (ACS). TR-069 is based on sending Remote
Procedure Calls (RPCs) between the ACS and the client device. RPCs are sent in Extensible Markup
Language (XML) format over HTTP or HTTPS.
An administrator can use an ACS to remotely set up the BM2022, modify its settings, perform
firmware upgrades, and monitor and diagnose it. In order to do so, you must enable the TR-069
feature on your BM2022 and then configure it appropriately. (The ACS server which it will use must
also be configured by its administrator.)
Figure 91 TR-069 Example
In this example, the BM2022 (A) receives data from at least 3 sources: A SIP server for handling
voice calls, an HTTP server for handling web services, and an ACS, for configuring the BM2022
remotely. All three servers are owned and operated by the clients Internet Service Provider.
However, without the configuration settings from the ACS, the BM2022 cannot access the other two
servers. Once the BM2022 receives its configuration settings and implements them, it can connect
to the other servers. If the settings change, it will once again be unable to connect until it receives
its updates from the ACS.
The BM2022 can be configured to periodically check for updates from the auto-configuration server
so that the end user need not be worried about it.

SNMP
An SNMP managed network consists of two main types of component: agents and a manager.
Figure 92 SNMP Management Model
An agent is a management software module that resides in a managed device (the BM2022). An
agent translates the local management information from the managed device into a form
compatible with SNMP. The manager is the console through which network administrators perform
network management functions. It executes applications that control and monitor managed
devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of
packets received, node port status etc. A Management Information Base (MIB) is a collection of
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects. The BM2022 supports MIB II that is defined in RFC-1213 and RFC-1215. The focus of
the MIBs is to let administrators collect statistical data and monitor status and performance.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol operations:
Get - Allows the manager to retrieve an object variable from the agent.
GetNext - Allows the manager to retrieve the next object variable from a table or list within an
agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it
initiates a Get operation, followed by a series of GetNext operations.
Set - Allows the manager to set values for object variables within an agent.
Trap - Used by the agent to inform the manager of some events.
Chapter 12 Maintenance
BM2022 Users Guide
174
The BM2022 sends traps to the SNMP manager when any of the following events occurs:
OMA-DM
When the BM2022 initiates communication with the server (often times at start up or after the first
time you turn it on), the server uploads commands, new files (if any), and other information used
by a service provider to customize the BM2022s features.
Device management works as follows:
1The server (A) sends out the query (1) to the BM2022 (B).
2The BM2022 responds by sending back its credentials (2), to which the server responds with its
credentials along with a string of management operations (3).
3The client responds to the management operations (4), perhaps confirming file alterations or
confirming receipt of file uploads and so on.
4The server disconnects from the BM2022 once all of its management operations have been carried
out.
Figure 93 OMA-DM Data Management
OMA-DM Authentication
In order to ensure the integrity of the connection between an OMA-DM server and the BM2022,
communication between the two is encoded using one of three common algorithms. They are not
intended to be used in lieu of proper digital security, but instead as a means of transmitting multiple
Table 76 SNMP Traps

disparate types of data over HTTP. Security encryption for communication is handled by different
processes configured elsewhere in the BM2022s web configurator
Basic Access Authentication Sends a persons user name and password in Base64. This
authentication protocol is supported by all browsers that are HTTP 1.0/1.1 compliant. Although
converted to Base64 for the sake of cross-compatibility, credentials are nonetheless passed
between the web browser and the server in plaintext, making it extremely easy to intercept and
read. As such, it is rarely used anymore.
Digest Access Authentication This protocol was designed to replace basic access
authentication. Instead of encoding a user name and password in plaintext, this protocol uses what
is known as an MD5 message authentication code. It allows the server to issue a single-use,
randomly generated number (known as a nonce) to the client (in this case, the web browser),
which then uses the number as the public key for encrypting its data. When the server receives
the encrypted data, it unlocks it using the key that was just provided. While stronger than basic
access authentication, this protocol is not as strong as, say, HMAC, or as secure as the client using
a client-side private key encryption scheme.
Hash Message Authentication Code Also known as HMAC, this code relies on cryptographic
hash functions to bolster an existing protocol, such as MD5. It is a method for generating a
stronger, significantly higher encryption key.
OMA-DM Data Model
Each device that conforms to the current OMA-DM standard has an identical data structure
embedded in its controlling firmware. This allows a similarly conforming OMA-DM server to navigate
the folder structure and to make file alterations where appropriate or required.
Figure 94 OMA-DM Data Model
In the example data model shown here, the parent folders must conform to the OMA-DM standard.
The child folders, on the other hand, can be customized on an individual basis. This allows the
parent folders to all maintain a consistent URI (Uniform Resource Identifier) across all devices that
meet the OMA-DM standards requirements.
For example, in the preceding figure the URI for the Games folder is ./Vendor/Games/. The ./
Vendor/ portion of the URI exists on all devices that conform to the OMA-DM standard. The
Games folder, however, may or may not exist depending on the services provided by the company
managing the device.

Daytime
A network protocol used by devices for debugging and time measurement. A computer can use this
protocol to set its internal clock but only if it knows in which order the year, month, and day are
returned by the server. Not all servers use the same format.
Time
A network protocol for retrieving the current time from a server. The computer issuing the
command compares the time on its clock to the information returned by the server, adjusts itself
automatically for time zone differences, then calculates the difference and corrects itself if there
has been any temporal drift.
NTP
NTP stands for Network Time Protocol. It is employed by devices connected to the Internet in order
to obtain a precise time setting from an official time server. These time servers are accurate to
within 200 microseconds.

FEATURE DESCRIPTION
Web-based Configuration and
Management Tool
Also known as the web configurator, this is a firmware-based
management solution for the BM2022. You must connect using a
compatible web browser in order to use it.
High Speed Wireless Internet
Access
The BM2022 is ideal for high-speed wireless Internet browsing.
WiMAX (Worldwide Interoperability for Microwave Access) is a
wireless networking standard providing high-bandwidth, wide-range
secured wireless service. The BM2022 is a WiMAX mobile station
(MS) compatible with the IEEE 802.16e standard.
Firewall The BM2022 is a stateful inspection firewall with DoS (Denial of
Service) protection. By default, when the firewall is activated, all
incoming traffic from the WAN to the LAN is blocked unless it is
initiated from the LAN. The BM2022s firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports
and logs.
Content Filtering The BM2022 can block access to web sites containing specified
keywords. You can define time periods and days during which
content filtering is enabled and include or exclude a range of users on
the LAN from content filtering.
Network Address Translation
(NAT)
Network Address Translation (NAT) allows the translation of an
Internet protocol address used within one network (for example a
private IP address used in a local network) to a different IP address
known within another network (for example a public IP address used
on the Internet).
Universal Plug and Play
(UPnP)
Your device and other UPnP enabled devices can use the standard
TCP/IP protocol to dynamically join a network, obtain an IP address
and convey their capabilities to each other.
Dynamic DNS Support With Dynamic DNS support, you can have a static hostname alias for
a dynamic IP address, allowing the host to be more easily accessible
from various locations on the Internet. You must register for this
service with a Dynamic DNS service provider.

from a centralized DHCP server. Your device has built-in DHCP server
capability enabled by default. It can assign IP addresses, an IP
default gateway and DNS servers to DHCP clients. Your device can
also act as a surrogate DHCP server (DHCP Relay) where it relays IP
address assignment from the actual real DHCP server to the clients.
IP Alias IP alias allows you to partition a physical network into logical
networks over the same Ethernet interface. Your device supports
three logical LAN interfaces via its single physical Ethernet interface
with the your device itself as the gateway for each LAN network.
Multiple SIP Accounts You can configure multiple voice (SIP) accounts.
SIP ALG Your device is a SIP Application Layer Gateway (ALG). It allows VoIP
calls to pass through NAT for devices behind it (such as a SIP-based
VoIP software application on a computer).
Dynamic Jitter Buffer The built-in adaptive buffer helps to smooth out the variations in
delay (jitter) for voice traffic (up to 60 ms). This helps ensure good
voice quality for your conversations.
Voice Activity Detection/
Silence Suppression
Voice Activity Detection (VAD) reduces the bandwidth that a call uses
by not transmitting when you are not speaking.
Comfort Noise Generation Your device generates background noise to fill moments of silence
when the other device in a call stops transmitting because the other
party is not speaking (as total silence could easily be mistaken for a
lost connection).
Echo Cancellation You device supports G.168 of at least 24 ms.
This an ITU-T standard for eliminating the echo caused by the sound
of your voice reverberating in the telephone receiver while you talk.
Time and Date Get the current time and date from an external server when you turn
on your BM2022. You can also set the time manually.
Logging Use the BM2022s logging feature to view connection history,
surveillance logs, and error messages.
Codecs G.711 (PCM -law and a-law), G729, G.729a
Fax Support T.38 FAX relay (FAX over UDP).
G.711 fax relay for fax calls and be able to renegotiate codec to
G.711 if a fax call is detected.
Ring Tones Supports different distinctive ring tones on each line.
Call Prioritization Prioritize VoIP traffic originating from the RJ-11 ports over any other
traffic.

Table 102 Voice Features
Call Park and Pickup Call park and pickup lets you put a call on hold (park) and then continue the
call (pickup). The caller must still pay while the call is parked.
When you park the call, you enter a number of your choice (up to eight digits),
which you must enter again when you pick up the call. If you do not enter the
correct number, you cannot pickup the call. This means that only someone
who knows the number you have chosen can pick up the call.
You can have more than one call on hold at the same time, but you must give
each call a different number.
Call Return With call return, you can place a call to the last number that called you (either
answered or missed). The last incoming call can be through either SIP or
PSTN.
Country Code Phone standards and settings differ from one country to another, so the
settings on your BM2022 must be configured to match those of the country
you are in. The country code feature allows you to do this by selecting the
country from a list rather than changing each setting manually. Configure the
country code feature when you move the BM2022 from one country to
another.
Do not Disturb
(DnD)
This feature allows you to set your phone not to ring when someone calls you.
You can set each phone independently using its keypad, or configure global
settings for all phones using the command line interpreter.
Auto Dial You can set the BM2022 to automatically dial a specified number immediately
whenever you lift a phone off the hook. Use the Web Configurator to set the
specified number. Use the command line interpreter to have the BM2022 wait
a specified length of time before dialing the number.
Phone config The phone configuration table allows you to customize the phone keypad
combinations you use to access certain features on the BM2022, such as call
waiting, call return, call forward, etc. The phone configuration table is
configurable in command interpreter mode.
Firmware update
enable / disable
If your service provider uses this feature, you hear a recorded message when
you pick up the phone when new firmware is available for your BM2022. Enter
*99# in your phones keypad to have the BM2022 upgrade the firmware, or
enter #99# to not upgrade. If your service provider gave you different
numbers to use, enter them instead. If you enter the code to not upgrade, you
can make a call as normal. You will hear the recording again each time you
pick up the phone, until you upgrade.
Call waiting This feature allows you to hear an alert when you are already using the phone
and another person calls you. You can then either reject the new incoming
call, put your current call on hold and receive the new incoming call, or end
the current call and receive the new incoming call.
Call forwarding With this feature, you can set the BM2022 to forward calls to a specified
number, either unconditionally (always), when your number is busy, or when
you do not answer. You can also forward incoming calls from one specified
number to another.
Caller ID The BM2022 supports caller ID, which allows you to see the originating
number of an incoming call (on a phone with a suitable display).
REN A Ringer Equivalence Number (REN) is used to determine the number of
devices (like telephones or fax machines) that may be connected to the
telephone line. Your device has a REN of three, so it can support three devices
per telephone port.
QoS (Quality of
Service)
Quality of Service (QoS) mechanisms help to provide better service on a per-
flow basis. Your device supports Type of Service (ToS) tagging and
Differentiated Services (DiffServ) tagging. This allows the device to tag voice
frames so they can be prioritized over the network.

APPENDIX A
WiMAX Security
Wireless security is vital to protect your wireless communications. Without it, information
transmitted over the wireless network would be accessible to any networking device within range.
User Authentication and Data Encryption
The WiMAX (IEEE 802.16) standard employs user authentication and encryption to ensure secured
communication at all times.
User authentication is the process of confirming a users identity and level of authorization. Data
encryption is the process of encoding information so that it cannot be read by anyone who does not
know the code.
WiMAX uses PKMv2 (Privacy Key Management version 2) for authentication, and CCMP (Counter
Mode with Cipher Block Chaining Message Authentication Protocol) for data encryption.
WiMAX supports EAP (Extensible Authentication Protocol, RFC 2486) which allows additional
authentication methods to be deployed with no changes to the base station or the mobile or
subscriber stations.
PKMv2
PKMv2 is a procedure that allows authentication of a mobile or subscriber station and negotiation of
a public key to encrypt traffic between the MS/SS and the base station. PKMv2 uses standard EAP
methods such as Transport Layer Security (EAP-TLS) or Tunneled TLS (EAP-TTLS) for secure
communication.
In cryptography, a key is a piece of information, typically a string of random numbers and letters,
that can be used to lock (encrypt) or unlock (decrypt) a message. Public key encryption uses key
pairs, which consist of a public (freely available) key and a private (secret) key. The public key is
used for encryption and the private key is used for decryption. You can decrypt a message only if
you have the private key. Public key certificates (or digital IDs) allow users to verify each others
identity.
RADIUS
RADIUS is based on a client-server model that supports authentication, authorization and
accounting. The base station is the client and the server is the RADIUS server. The RADIUS server
handles the following tasks:
Authentication
Determines the identity of the users.
Appendix A WiMAX Security
BM2022 Users Guide
206
Authorization
Determines the network services available to authenticated users once they are connected to the
network.
Accounting
Keeps track of the clients network activity.
RADIUS is a simple package exchange in which your base station acts as a message relay between
the MS/SS and the network RADIUS server.
Types of RADIUS Messages
The following types of RADIUS messages are exchanged between the base station and the RADIUS
server for user authentication:
Access-Request
Sent by an base station requesting authentication.
Access-Reject
Sent by a RADIUS server rejecting access.
Access-Accept
Sent by a RADIUS server allowing access.
Access-Challenge
Sent by a RADIUS server requesting more information in order to allow access. The base station
sends a proper response from the user and then sends another Access-Request message.
The following types of RADIUS messages are exchanged between the base station and the RADIUS
server for user accounting:
Accounting-Request
Sent by the base station requesting accounting.
Accounting-Response
Sent by the RADIUS server to indicate that it has started or stopped accounting.
In order to ensure network security, the access point and the RADIUS server use a shared secret
key, which is a password they both know. The key is not sent over the network. In addition to the
shared key, password information exchanged is also encrypted to protect the network from
unauthorized access.
Diameter
Diameter (RFC 3588) is a type of AAA server that provides several improvements over RADIUS in
efficiency, security, and support for roaming.
Security Association
The set of information about user authentication and data encryption between two computers is
known as a security association (SA). In a WiMAX network, the process of security association has
three stages.
Appendix A WiMAX Security
BM2022 Users Guide 207
Authorization request and reply
The MS/SS presents its public certificate to the base station. The base station verifies the
certificate and sends an authentication key (AK) to the MS/SS.
Key request and reply
The MS/SS requests a transport encryption key (TEK) which the base station generates and
encrypts using the authentication key.
Encrypted traffic
The MS/SS decrypts the TEK (using the authentication key). Both stations can now securely
encrypt and decrypt the data flow.
CCMP
All traffic in a WiMAX network is encrypted using CCMP (Counter Mode with Cipher Block Chaining
Message Authentication Protocol). CCMP is based on the 128-bit Advanced Encryption Standard
(AES) algorithm.
Counter mode refers to the encryption of each block of plain text with an arbitrary number, known
as the counter. This number changes each time a block of plain text is encrypted. Counter mode
avoids the security weakness of repeated identical blocks of encrypted text that makes encrypted
data vulnerable to pattern-spotting.
Cipher Block Chaining Message Authentication (also known as CBC-MAC) ensures message
integrity by encrypting each block of plain text in such a way that its encryption is dependent on the
block before it. This series of chained blocks creates a message authentication code (MAC or
CMAC) that ensures the encrypted data has not been tampered with.
Authentication
The BM2022 supports EAP-TTLS authentication.
EAP-TTLS (Tunneled Transport Layer Service)
EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-
side authentications to establish a secure connection (with EAP-TLS digital certifications are needed
by both the server and the wireless clients for mutual authentication). Client authentication is then
done by sending username and password through the secure connection, thus client identity is
protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication
methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2.

APPENDIX D
IP Addresses and Subnetting
This appendix introduces IP addresses and subnet masks.
IP addresses identify individual devices on a network. Every networking device (including
computers, servers, routers, printers, etc.) needs an IP address to communicate across the
network. These networking devices are also known as hosts.
Subnet masks determine the maximum number of possible hosts on a network. You can also use
subnet masks to divide one network into multiple sub-networks.
Introduction to IP Addresses
One part of the IP address is the network number, and the other part is the host ID. In the same
way that houses on a street share a common street name, the hosts on a network share a common
network number. Similarly, as each house has its own house number, each host on the network has
its own unique identifying number - the host ID. Routers use the network number to send packets
to the correct network, while the host ID determines to which host on the network the packets are
delivered.
Structure
An IP address is made up of four parts, written in dotted decimal notation. Each of these four parts
is known as an octet. An octet is an eight-digit binary number (for example 11000000, which is 192
in decimal notation).
Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in
decimal.
Appendix D IP Addresses and Subnetting
BM2022 Users Guide
244
The following figure shows an example IP address in which the first three octets (192.168.1) are
the network number, and the fourth octet (16) is the host ID.
Figure 164 Network Number and Host ID
How much of the IP address is the network number and how much is the host ID varies according
to the subnet mask.
Subnet Masks
A subnet mask is used to determine which bits are part of the network number, and which bits are
part of the host ID (using a logical AND operation). The term subnet is short for sub-network.
A subnet mask has 32 bits. If a bit in the subnet mask is a 1 then the corresponding bit in the IP
address is part of the network number. If a bit in the subnet mask is 0 then the corresponding bit
in the IP address is part of the host ID.
The following example shows a subnet mask identifying the network number (in bold text) and host
ID of an IP address (192.168.1.2 in decimal).
By convention, subnet masks always consist of a continuous sequence of ones beginning from the
leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.

Host ID 00000010
Appendix D IP Addresses and Subnetting
BM2022 Users Guide 245
Subnet masks can be referred to by the size of the network number part (the bits with a 1 value).
For example, an 8-bit mask means that the first 8 bits of the mask are ones and the remaining 24
bits are zeroes.
Subnet masks are expressed in dotted decimal notation just like IP addresses. The following
examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks.
Network Size
The size of the network number determines the maximum number of possible hosts you can have
on your network. The larger the number of network number bits, the smaller the number of
remaining host ID bits.
An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 with a 24-bit
subnet mask, for example). An IP address with host IDs of all ones is the broadcast address for that
network (192.168.1.255 with a 24-bit subnet mask, for example).
As these two IP addresses cannot be used for individual hosts, calculate the maximum number of
possible hosts in a network as follows:
Notation
Since the mask is always a continuous number of ones beginning from the left, followed by a
continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the
number of ones instead of writing the value of each octet. This is usually specified by writing a /
followed by the number of bits in the mask after the address.
For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128.

The following table shows some possible subnet masks using both notations.
Subnetting
You can use subnetting to divide one network into multiple sub-networks. In the following example
a network administrator creates two sub-networks to isolate a group of servers from the rest of the
company network for security reasons.
In this example, the company network address is 192.168.1.0. The first three octets of the address
(192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum
of 28 2 or 254 possible hosts.
The following figure shows the company network before subnetting.
Figure 165 Subnetting Example: Before Subnetting
You can borrow one of the host ID bits to divide the network 192.168.1.0 into two separate sub-
networks. The subnet mask is now 25 bits (255.255.255.128 or /25).
The borrowed host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25
and 192.168.1.128 /25.

The following figure shows the company network after subnetting. There are now two sub-
networks, A and B.
Figure 166 Subnetting Example: After Subnetting
In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 2 or 126
possible hosts (a host ID of all zeroes is the subnets address itself, all ones is the subnets
broadcast address).
192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask
255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to
an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126.
Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.
Example: Four Subnets
The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two
subnets. Similarly, to divide a 24-bit address into four subnets, you need to borrow two host ID
bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits
(11111111.11111111.11111111.11000000) or 255.255.255.192.
Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a host ID of all
zeroes is the subnet itself, all ones is the subnets broadcast address).

Configuring IP Addresses
Where you obtain your network number depends on your particular situation. If the ISP or your
network administrator assigns you a block of registered IP addresses, follow their instructions in
selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user
account and the ISP will assign you a dynamic IP address when the connection is established. If this
is the case, it is recommended that you select a network number from 192.168.0.0 to
192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block of addresses
specifically for private use; please do not use any other number unless you are told otherwise. You
must also enable Network Address Translation (NAT) on the BM2022.
Once you have decided on the network number, pick an IP address for your BM2022 that is easy to
remember (for instance, 192.168.1.1) but make sure that no other device on your network is using
that IP address.
The subnet mask specifies the network number portion of an IP address. Your BM2022 will compute
the subnet mask automatically based on the IP address that you entered. You don't need to change
the subnet mask computed by the BM2022 unless you are instructed to do otherwise.
Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the
Internet (running only between two branch offices, for example) you can assign any IP addresses to
the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has
reserved the following three blocks of IP addresses specifically for private networks:
10.0.0.0 10.255.255.255
172.16.0.0 172.31.255.255
192.168.0.0 192.168.255.255
You can obtain your IP address from the IANA, from an ISP, or it can be assigned from a private
network. If you belong to a small organization and your Internet access is through an ISP, the ISP
can provide you with the Internet addresses for your local networks. On the other hand, if you are
part of a much larger organization, you should consult your network administrator for the
appropriate IP addresses.
Regardless of your particular situation, do not create an arbitrary IP address; always follow the
guidelines above. For more information on address assignment, please refer to RFC 1597, Address
Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.

IP Address Conflicts
Each device on a network must have a unique IP address. Devices with duplicate IP addresses on
the same network will not be able to access the Internet or other resources. The devices may also
be unreachable through the network.
Conflicting Computer IP Addresses Example
More than one device can not use the same IP address. In the following example computer A has a
static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to
computer B which is a DHCP client. Neither can access the Internet. This problem can be solved by
assigning a different static IP address to computer A or setting computer A to obtain an IP address
automatically.
Figure 167 Conflicting Computer IP Addresses Example
Conflicting Router IP Addresses Example
Since a router connects different networks, it must have interfaces using different network
numbers. For example, if a router is set between a LAN and the Internet (WAN), the routers LAN
and WAN addresses must be on different subnets. In the following example, the LAN and WAN are
on the same subnet. The LAN computers cannot access the Internet because the router cannot
route between networks.

Conflicting Computer and Router IP Addresses Example
More than one device can not use the same IP address. In the following example, the computer and

APPENDIX E
Importing Certificates
This appendix shows you how to import public key certificates into your web browser.
Public key certificates are used by web browsers to ensure that a secure web site is legitimate.
When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few,
receives a certificate request from a website operator, they confirm that the web domain and
contact information in the request match those on public record with a domain name registrar. If
they match, then the certificate is issued to the website operator, who then places it on the site to
be issued to all visiting web browsers to let them know that the site is legitimate.
Many Huawei products issue their own public key certificates. These can be used by web browsers
on a LAN or WAN to verify that they are in fact connecting to the legitimate device and not one
masquerading as it. However, because the certificates were not issued by one of the several
organizations officially recognized by the most common web browsers, you will need to import the
Huawei-created certificate into your web browser and flag that certificate as a trusted authority.
Note: You can see if you are browsing on a secure website if the URL in your web
browsers address bar begins with https:// or there is a sealed padlock icon
( ) somewhere in the main browser window (not all browsers show the padlock
in the same location.)
