Authentication Type
Description
WEP
The Wireless Encryption Protocol (WEP) is an older security protocol that allows
any wireless clients within the radio range to access your network without an
encryption key. This setting provides the least level of security. For security
reasons, do not select this setting unless there is a compatibility issue with an
older wireless client. For added protection, set an encryption key on your access
point and enter the same key into your other wireless clients.
WPA-PSK
This setting provides good security and works with most newer wireless clients.
This setting requires an encryption key on the access point and the wireless client
configured to use Wi-Fi Protected Access – Pre-Shared Key (WPA-PSK) with the
same encryption key.
WPA2-PSK
This setting requires that wireless clients use only WPA2-PSK to access your
networks. An encryption key must be configured on the access point and entered
into the wireless client. WPA2-PSK is currently the most secure Wi-Fi encryption
protocol but may not be available on older wireless clients.
WPA-PSK Mixed
This setting allows a wireless client to use either WPA-PSK or WPA2-PSK to
access your network. An encryption key must be configured on the access point
and the same key must be entered on the wireless client.
Select the Encryption Key option:
If you select Use default encryption key radio button, you can continue to use the encryption key
that came with your gateway.
If you select Set custom encryption key radio button, you have to create a custom encryption key.
You can define a 64-bit or 128-bit hexadecimal/ASCII encryption key. For 64-bit encryption, enter a
10-digit hexadecimal number or 5 ASCII characters. For 128-bit encryption, enter a 26-digit
hexadecimal number or 13 ASCII characters. This security key will be used by all clients to access
your wireless network.

Configuring DMZ Mode
Objective
To configure DMZ mode for a computer.
DMZ mode is a special firewall mode that is used for hosting applications if an application does not function
properly using the Allow individual application(s) options. When in DMZ mode, the designated computer:
•
Shares your gateway’s IP address (router address).
•
Appears as if it is directly connected to the Internet.
•
Has all of the unassigned TCP and UDP ports opened and directing towards it.
•
Can receive unsolicited network traffic from the Internet.
Although the computer in DMZ mode appears to the Internet users as if it is directly connected to the Internet,
but it is still protected by your gateway's firewall. All traffic is inspected by the firewall’s Stateful Packet
Inspection (SPI) engine and all known hacker attacks continue to be blocked.
Use the DMZ modes with caution. A computer in the DMZ mode is less secure because all available
ports are open and all incoming Internet traffic is directed to this computer.
Steps
1.
On the Settings tab, click Firewall, and then click Applications, Pinholes and DMZ.
2.
Navigate to the Select a computer panel.
3.
Select the required computer where you want to host the application(s) in the Select a computer
panel.
Configuring DMZ Mode
61
HomePortal® Intelligent Gateway 9.3.1.10 Configuration Guide
Note
Managing Firewall Settings
Verify that the computer you selected is configured for DHCP. If the selected computer is not
configured for DHCP, configure the DHCP settings and restart the computer. After the
computer restarts, it receives an IP address from the gateway and all unassigned TCP and
UDP ports are forwarded to it.
4.
Navigate to the DMZ Mode panel.
5.
Select the DMZ Mode option:
If you select DMZ Mode radio button, the network traffic is directly routed to the selected
computer. In DMZ mode, the designated computer is connected to the Internet through the
gateway, and can receive unsolicited network traffic from the Internet.
If you select DMZ Plus Mode radio button, the gateway assigns a broadband/WAN IP to the
selected computer. In DMZplus mode, the designated computer is directly connected to the
Internet, has all unassigned TCP and UDP ports opened, and can receive unsolicited network traffic
from the Internet.
If you select NO DMZ radio button, configured firewall rules are applicable for the selected
computer.
6.
Click Save.
Disabling Attack Detection
Objective
To disable a specific port in the attack detection panel.
By default, attack detection is enabled on these ports by the firewall. However, some applications and devices
may require the use of specific data ports listed here. The gateway allows users to open the necessary ports
through the firewall.
Steps
1.
On the Settings tab, click Firewall, and then click Advanced Configuration.
2.
Navigate to the Attack Detection panel.
Disabling Attack Detection
62
HomePortal® Intelligent Gateway 9.3.1.10 Configuration Guide
3.
Managing Firewall Settings
Clear the TCP/UDP Port Scan check box.
If you disable this feature, the firewall does not detect UDP and TCP port scans, and communicates the
port scan packets to the computer. A port scan is a series of messages sent by an external entity
attempting to break into a computer to learn which computer network services associated with UDP
and TCP ports are provided by the computer.
4.
Clear the Packet Flood (SYN/UDP/ICMP/Other) check box.
If you disable this feature, the firewall does not check for SYN, UDP, ICMP, and other types of packet
floods on the local and Internet facing interfaces.
5.
Clear the Invalid TCP Flag Attacks (XMAS) check box.
If you disable this feature, the firewall does not scan inbound and outbound packets for invalid TCP
Flag settings or TCP XMAS attack and communicates the associated packets to the computer.
6.
Clear the Invalid TCP Flag Attacks (NULL) check box.
If you disable this feature, the firewall does not scan inbound and outbound packets for invalid TCP
Flag settings or TCP NULL attack and communicates the associated packets to the computer.
7.
Clear the Invalid ICMP Detection check box.
If you disable this feature, the firewall does not check for invalid ICMP type/code types and
communicates the associated packets to the computer.
8.
Click Save.
Managing Outbound Traffic
Objective
To configure the firewall for blocking or passing the outbound network traffic from your network.
Steps
1.
On the Settings tab, click Firewall, and then click Advanced Configuration.
2.
Navigate to view the Outbound Protocol Control panel.
Managing Outbound Traffic
63
HomePortal® Intelligent Gateway 9.3.1.10 Configuration Guide
3.
Managing Firewall Settings
Select the required check box(es) in the Outbound Protocol Control panel.
If you select any of the check box(es) in the Outbound Protocol Control panel, the firewall allows the
associated traffic to pass through the firewall from the network to the Internet.
4.
Note
Click Save.
Allowing outbound traffic does not mean that the firewall automatically allows this type of traffic to
pass through the firewall. Even if a particular protocol/application type is allowed, the firewall still
checks and blocks all unsolicited traffic unless the firewall is configured to pass the traffic by hosting an
application profile.
Configuring Firewall Security Enhancements
Objective
To configure the firewall rules for filtering the traffic passing through the gateway.
Steps
1.
On the Settings tab, click Firewall, and then click Advanced Configuration.
2.
Navigate to the Enchanced Security panel.
3.
Select the Stealth Mode check box to enable the stealth mode.
Configuring Firewall Security Enhancements
64
HomePortal® Intelligent Gateway 9.3.1.10 Configuration Guide
Managing Firewall Settings
If you enable stealth mode, the gateway firewall does not return any information in response to
network queries. This discourages intruders from accessing your network.
4.
Select the Block Ping check box to disable the execution of external ping requests.
If you enable Block Ping, your network will block all ping requests.
If you disable Block Ping, intruders can use ping to launch an attack against your network since
ping can determine the IP address of the network (for example, 105.246.172.72) from the domain
name (for example, www.mynetworkdevice.com).
5.
Select the Block Dsldiag check box to disable the execution of external DSL diagnostic requests.
If you enable Block Dsldiag, the dsldiagd daemon running on the device blocks the remote user from
connecting to the gateway and checking the DSL statistics, training history, and so on.
6.
Enter the time duration in seconds in the UDP Session Timeout text box.
The gateway terminates the UDP connection request after the specified duration.
7.
Enter the time duration in seconds in the TCP Session Timeout text box.
The gateway terminates the TCP connection request after the specified duration.
8.
Click Save.
Configuring Application Layer Gateway
Objective
To enable or disable Application Layer Gateway (ALG) on the firewall of the gateway.
If you enable SIP ALG, client applications can use dynamic TCP/UDP ports to communicate with the known ports
used by the server applications, even though a firewall configuration allows only a limited number of known
ports.
If you disable ALG, the ports become blocked and you must specially open up a large number of ports in the
firewall, rendering the network vulnerable to attacks on those ports.
Steps
1.
On the Settings tab, click Firewall, and then click Advanced Configuration.
2.
Navigate to the Application Layer Gateways panel.
3.
Enable or disable the SIP ALG on the gateway firewall by selecting or clearing the check box.

Glossary
Term
Description
Access Point
A device that transports data between a wireless network and a wired network. With
the help of the gateway, a wireless base station is an example of an access point that
acts between a wireless node and with other wired computers and peripherals.
Default Gateway
A device that is placed between network segments (or “subnets”) to ensure that traffic
is properly routed between different subnets. To communicate with a device on another
network, users have to know the default gateway’s IP address.
DHCP (Dynamic Host Configuration
Protocol)
A TCP/IP protocol that allows servers to assign IP addresses dynamically to PCs and
workstations. The PC or workstation “borrows” the IP address for a period of time, then
the IP address returns to the DHCP server for reassignment.
DMZ (Demilitarized Zone)
A computer or small subnetwork that sits between a trusted internal network (such as a
LAN), and an untrusted external network (such as the Internet). Typically, the DMZ
contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers,
SMTP (email) servers, and DNS servers.
DNS (Domain Name System)
The DNS is the way that Internet domain names (such as http://www.2wire.com) are
located and translated into IP addresses.
DSLAM (Digital Subscriber Line
Access Multiplexer)
A device found in telephone company central offices that takes a number of DSL
subscriber lines and concentrates them onto a single ATM line.
Ethernet
A type of local area network that operates over twisted wire and cable at speeds of up
to 10 Mbps.
ICMP (Internet Control Message
Protocol)
ICMP supports packets containing error, control, and informational messages. For
example, the PING command uses ICMP to test an Internet connection.
Although ICMP is generally harmless, there are some message types that should be
dropped. Redirect (5), Alternate Host Address (6), and Router Advertisement (9) can be
used to redirect traffic from your site. Echo (8), Timestamp (13), and Address Mask
Request (17) can be used to obtain information on whether the host is up, the local time,
and the address mask used on your network, respectively. ICMP messages are also
sometimes used as part of DOS attacks (such as flood ping or ping of death).
Invalid TCP Flags
Combination of TCP flags (such as SYN/FIN) that signal a malicious attempt to get past
the firewall.
IP (Internet Protocol)
The standard signaling method used for all communication over the Internet.
IP Address
A numeric identifier for your computer. Just as the post office delivers mail to your
home address, servers know where to deliver data to your computer based on your IP
address. IP addresses can be dynamic, meaning that your computer “borrows” the IP
address for the necessary timeframe, or they can be fixed, meaning that the number is
permanently assigned to your computer.
Local Area Network
A network connecting a number of computers to each other or to a central server so
that the computers can share programs and files.
MAC Address (Media Access
Control Address)
A hardware address that has been embedded into the Network Interface Card (NIC) by
its vendor to uniquely identify each node, or point of connection, of a network.
Map to Host Port
When set (not left blank or set to 0), this value provides the mapping offset to the local
computer. For example, if this value is set to 4000 and the range being opened is 100 to
108, the forwarded data to the first value in the range will be sent to 4000. Subsequent
ports will be mapped accordingly; 101 will be sent to 4001, 102 will be sent to 4002, and
so on.

Term
Glossary
Description
MTU (Maximum Transmission Unit)
The largest size packet or frame, specified in octets (eight-bit bytes), that can be sent
from a computer to the network. The Internet's TCP uses the MTU to determine the
maximum size of each packet in any transmission. If the MTU is too large, the packet
may have to be retransmitted if it encounters a router that can't handle such a large
packet. Too small MTU size means relatively more header overhead and more
acknowledgements that have to be sent and handled. Most computer operating
systems provide a default MTU value that is suitable for most users. In general, Internet
users should follow the advice of their Internet Service Provider (ISP) about whether to
change the default value and what to change it to.
NAT (Network Address Translation)
Enables a LAN to use one set of IP addresses for internal traffic and a second set of IP
addresses for external traffic. This feature is used by the gateway so an end user can
have an internal computer network in their home, with all its computers using internal IP
addresses, using only one routable IP address, which accesses the outside (Internet).
PAT (Port Address Translation)
Allows hosts on a LAN to communicate with the rest of a network (such as the Internet)
without revealing their own private IP address. All outbound packets have their IP
address translated to the router’s external IP address. Replies come back to the router,
which then translates them back into the private IP address of the original host for final
delivery.
PPP (Point-to-Point Protocol)
A protocol that allows a computer to access the Internet using a dial-up phone line and
a high-speed modem. This can be accomplished over Ethernet (PPPoE), or over
Asynchronous Transfer Mode (ATM, PPPoA).
PPPoA (Point-to-Point Protocol
over ATM)
A specification for connecting multiple computer users on an Ethernet LAN to a remote
site through common customer premises equipment (such as a modem). PPPoA
combines the Point-to-Point Protocol (PPP), commonly used in dialup connections, with
the ATM (Asynchronous Transfer Mode) protocol, which supports multiple users in a
LAN.
PPPoE (Point-to-Point Protocol
over Ethernet)
A specification for connecting multiple computer users on an Ethernet LAN to a remote
site through common customer premises equipment (such as a modem). PPPoE
combines the Point-to-Point Protocol (PPP), commonly used in dialup connections, with
the Ethernet protocol, which supports multiple users in a LAN.
Protocol Timeout
The amount of time (in seconds) during which a connection in the specified range
remains open when there is no data transfer. After a connection has been established on
a given port, the sender and receiver usually determine when the session is finished and
the connection is closed. However, if the connection is left open and data transfer stops,
the gateway must eventually close the connection and reclaim the resources in order to
protect your network. In some cases, the gateway might close the application during
normal operation (for example, if there is a long pause between data transfer). In such
cases, lengthening the timeout may help.
PVC (Permanent Virtual Circuit)
A virtual circuit that is permanently available. Used to establish connections between
hosts that communicate frequently.
Router
The central switching device in a packet-switched computer network that directs and
controls the flow of data through the network.

Subnet Mask
Glossary
Description
The IP addressing system allows subnetworks or “interchanges” to be created, and
devices numbers or “extensions” to be established within these subnetworks. These
numbers are created using a mathematical device called a subnet mask. A subnet mask,
like the IP address, is a set of four numbers in dotted decimal notation. Subnet masks
typically take three forms:
• 255.0.0.0
• 255.255.0.0
• 255.255.255.0
The number 255 “masks” out the corresponding number of the IP address, resulting in
IP address numbers that are valid for the network. For example, an IP address of
123.45.67.89 and a subnet mask of 255.255.255.0 results in a sub network number of
123.45.67.0 and a device number of 89.
The subnet mask used for the network typically corresponds to the class of IP address
assigned, as shown in the following table:
IP Address
Class
Dotted-Decimal
Notation
Ranges Corresponding
Subnet Mask
Class A
1.xxx.xxx.xxx to
126.xxx.xxx.xxx
255.0.0.0
Class B
128.0.xxx.xxx to
191.255.xxx.xxx
255.255.0.0
Class C
192.0.0.xxx to
223.255.255.xxx
255.255.255.0
SYN Flood
A method that the user of a hostile client program can use to conduct a denial-ofservice (DOS) attack on a computer server. The hostile client repeatedly sends SYN
(synchronization) packets to every port on the server, using fake IP addresses.
TCP/IP (Transmission Control
Protocol/Internet Protocol)
A method of packet-switched data transmission used on the Internet. The protocol
specifies the manner in which a signal is divided into parts, as well as the manner in
which “address” information is added to each packet to ensure that it reaches its
destination and can be reassembled into the original message.
UDP (User Datagram Protocol)
A TCP/IP protocol describing how data packets reach application programs within a
destination computer.
VPI (Virtual Path Identifier)
Identifier contained in the ATM cell header to designate the virtual path on the physical
ATM link.
VCI (Virtual Channel Identifier)
Identifier contained in the ATM cell header to designate the virtual channel on the
physical ATM link.
Wireless
Transmission of data over radio waves rather than wiring.
