Welcome
Thank you for choosing the Wireless-N Gigabit Security Router with VPN. The Wireless-N Gigabit
Security Router with VPN is an advanced Internet-sharing network solution for your small business needs.
The Router features a built-in 4-Port full-duplex 10/100/1000 Ethernet switch to connect four PCs directly,
or you can connect more hubs and switches to create as big a network as you need. Like any wireless router,
it lets multiple computers in your office share an Internet connection through both wired and wireless
connections. It can also be used as an intranet router to aggregate traffic to a company backbone network.
The Router has a built-in access point that supports the latest 802.11n draft specification by IEEE. It also
supports 802.11g and 802.11b clients in a mixed environment. The access point can support an 11n data
rate of up to 300 Mbps. Besides having a higher data rate, 802.11n technology also promises longer
coverage by using multiple antennas to transmit and receive data streams in different directions. Users are
encouraged to upgrade their firmware through www.linksys.com when 802.11n specification is finalized by
IEEE to ensure compatibility with all the wireless-N devices.
The Wireless-N Gigabit Security Router with VPN is equipped with advanced security technologies like
Intrusion Prevention System (IPS), Stateful Packet Inspection (SPI) Firewall, IP based Access List (IP
ACL), and Network Address Port Translation (NAPT, also called NAT as a more generic term). These
technologies work together by providing self-defensive strategy. Malicious attack traffic is identified,
classified, and stopped in real time while passing through the Router. Users are encouraged to update their
IPS signature file to stay current on stopping malicious worms. The SPI Firewall provides deep packet
inspection to analyze packets in network layer (IP) and transport layer (TCP, UDP) to block illegal packet
transactions. Users can also use IP based ACL to limit traffic to a specific source, destination and protocol.
NAPT allows users to open specific TCP/UDP port numbers to the Internet to provide limited service while
minimizing harmful traffic at the same time.
The Virtual Private Network (VPN) capability is another security feature that creates encrypted “tunnels”
through the Internet, allowing up to five remote offices and five traveling users to securely connect into
your office network from off-site. Users connecting through a VPN tunnel are attached to your company's
network with secure access to files, e-mail, and your intranet as if they were in the building. You can also
use the VPN capability to allow users on your small office network to securely connect out to a corporate
network. The QoS features provide consistent voice and video quality throughout your business.

Chapter 2: Networking and Security
Basics
An Introduction to LANs
A Router is a network device that connects
multiple networks together and forward traffic
based on IP destination of each packet.
The Wireless-N Gigabit Security Router can connect your local area network (LAN) or a group of PCs
interconnected in your home or office to the Internet. You can use one public IP address from the ISP
through WAN port and use the router’s Network Address Translation (NAT) technology to share this single
NAT (Network Address Translation):
IP address
NAT technology translates IP
among all the users.
ddresses of a local area network to a The Router’s Network Address Port Translation (NAPT or NAT)
technology protects your network of PCs so users different IP address for the Internet. on the Internet
cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by
inspecting the first packet coming in through the Internet port before delivery to the final destination on one
of the Ethernet ports. The Router inspects Internet port services like the web server, ftp server, or other
LAN: the computers and networking products that
Internet
applications, and, if allowed, it will forward the packet to the
make up your local network
appropriate PC on the LAN side.
Multiple Wireless-N Gigabit Security Routers can also be used to connect multiple LANs
together. This usually applies to a medium-sized or larger company where you want to
divide your network into multiple IP subnets to increase the intranet throughput and
reduce the size of the IP broadcast domain and its interference. In this case, you need one
WRVS4400Nv2 for each subnetwork and you can connect all the WAN ports to a second
level Router or switch to the Internet. Note that the second level Router only forwards
data packets through a wired network so you don’t have to use the Wireless-N Gigabit
Security Router. You can use any wired router in the Linksys family, e.g. RVS4000,
which has 4 LAN ports and 1 WAN port.
The following diagram shows an example that consists of two levels of routers and
multiple LANs inter-connected together. The wireless network is only available at the
first level of router to provide end user connections. The second level router can connect
to dedicated Server PCs or routers that aggregates traffic from different LANs.
The Use of IP Addresses
IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and
routers, requires an IP address to identify its location, or address, on the network. This applies to both the
Internet and LAN connections.
There are two ways of assigning IP addresses to your network devices.
NOTE: Since the Router is a device that connects two networks, it needs two IP addresses—one for the
LAN, and one for the Internet. In this User Guide, you’ll see references to the “Internet IP address” and the
“LAN IP address.”
Since the Router uses NAT technology, the only IP address that can be seen from the Internet for your
network is the Router’s Internet IP address. However, even this Internet IP address can be hidden on the
Internet by suppressing PING response.
A static IP address is a fixed IP address that you assign manually to a PC or other device on the network.
Since a static IP address remains valid until you disable it, static IP addressing ensures that the device
assigned it will always have that same IP address until you change it. Static IP addresses are commonly
used with dedicated network devices such as server PCs or print servers. Since a user’s PC is moving
around in a network and is being powered on or off, it does not require a dedicated IP address that could be
a precious resource in your network.
If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if
they have assigned a static IP address to your account. If so, you will need that static IP address when
configuring the Router. You can get the information from your ISP.
A dynamic IP address is automatically assigned to a device on the network. This IP address is called
dynamic because it is only temporarily assigned to the PC or other device. After a certain time period, it
expires and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has
expired, the DHCP server will assign it a new dynamic IP address. Most ISPs use dynamic IP addresses for
their customers. By default, the Router’s Internet Connection Type is Obtain an IP automatically
(DHCP).
For DSL users, many ISPs may require you to log on with a user name and password to gain access to the
Internet. This is a dedicated, high-speed connection type called Point-to-Point Protocol over Ethernet
(PPPoE). PPPoE is similar to a dial-up connection, which establishes a PPP session with an ISP server
through the DSL connection. The server will also provide the Router with a dynamic IP address to
establish a connection to the Internet.
A DHCP server can either be located on a designated PC on the network or another network device, such as
the Router. The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you
from having to assign IP addresses manually every time a new user is added to your network. For this
Wireless-N Router, a DHCP client is running on a WAN port for most configurations. A DHCP server is
running on the LAN side to provide services.
By default, a DHCP server is enabled on the Router. If you already have a DHCP server running on your
network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your
network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the
Router, refer to the Basic Setup section in “Chapter 6: Setting Up and Configuring the Router.”
Static IP address: a fixed address assigned to a computer or device that is connected to a network.
Dynamic IP address: a temporary IP address assigned by a DHCP server.
DHCP (Dynamic Host Configuration Protocol): a protocol that lets one device on a local network, known
as a DHCP server, assign temporary IP addresses to the other network devices, typically computers.
IPS is an advanced technology to protect your network from malicious attacks. IPS works together with
your SPI Firewall, IP Based Access List (IP ACL), Network Address Port Translation (NAPT), and Virtual
Private Network (VPN) to achieve the highest amount of securities.
IPS works by providing real-time detection and prevention as an in-line module in a router. The Wireless-N
Security Router has hardware-based acceleration for real-time pattern matching for malicious attacks. It
actively filters and drops malicious TCP/UDP/ICMP/IGMP packets and can reset TCP connections. This
protects your client PCs and servers running various operating systems including Windows, Linux, and
Solaris from network worm attacks. However, this system does not prevent viruses attached emails.
The signature file is the heart of the IPS system. It is similar to the Virus definition files on your PC’s
Anti-Virus programs. IPS uses this file to match against packets coming in to the Router and performs
actions accordingly. As of today, the Wireless-N Router is shipped with signature file version 1.1.4 and
with a total of 1048 rules. The rules cover the following categories: DDoS, Buffer Overflow, Access
Control, Scan, Trojan Horse, Misc., P2P, IM, Virus, Worm, and Web Attacks.
Customers are encouraged to update their IPS signature file regularly to prevent any new type of attacks
on the Internet.
Chapter 3: Planning Your Virtual
Private Network (VPN)
Why do I need a VPN?
Computer networking provides a flexibility not available when using an archaic, paper-based system. With
this flexibility, however, comes an increased risk in security. This is why firewalls were first introduced.
Firewalls help to protect data inside of a local network. But what do you do once information is sent
outside of your local network, when e-mails are sent to their destination, or when you have to connect to
your company's network when you are out on the road? How is your data protected?
That is when a VPN can help. VPNs are called Virtual Private Networks because they secure data moving
outside of your network as if it were still within that network.
When data is sent out across the Internet from your computer, it is always open to attacks. You may already
have a firewall, which will help protect data moving around or held within your network from being
corrupted or intercepted by entities outside of your network, but once data moves outside of your
network—when you send data to someone via e-mail or communicate with an individual over the
Internet—the firewall will no longer protect that data.
At this point, your data becomes open to hackers using a variety of methods to steal not only the data you
are transmitting but also your network login and security data. Some of the most common methods are as
follows:
1) MAC Address Spoofing
Packets transmitted over a network, either your local network or the Internet, are preceded by a packet
header. These packet headers contain both the source and destination information for that packet to transmit
efficiently. A hacker can use this information to spoof (or fake) a MAC address allowed on the network.
With this spoofed MAC address, the hacker can also intercept information meant for another user.
2) Data Sniffing
Data “sniffing” is a method used by hackers to obtain network data as it travels through unsecured
networks, such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network
diagnostic tools, are often built into operating systems and allow the data to be viewed in clear text.
3) Man in the middle attacks
Once the hacker has either sniffed or spoofed enough information, he can now perform a “man in the
middle” attack. This attack is performed, when data is being transmitted from one network to another, by
rerouting the
vpn (virtual private network): a security measure to protect data as it leaves one network and goes to
another over the Internet
packet: a unit of data sent over a network
These are only a few of the methods hackers use and they are always developing more. Without the
security of your VPN, your data is constantly open to such attacks as it travels over the Internet. Data
travelling over the Internet will often pass through many different servers around the world before
reaching its final destination. That's a long way to go for unsecured data and this is when a VPN serves its
purpose.
What is a VPN?
A VPN, or Virtual Private Network, is a connection between two endpoints—a VPN Router, for
instance—in different networks that allows private data to be sent securely over a shared or public
network, such as the Internet. This establishes a private network that can send data securely between
these two locations or networks.
This is done by creating a “tunnel”. A VPN tunnel connects the two PCs or networks and allows data
to be transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a
connection secured by encrypting the data sent between the two networks.
There are two popular ways to establish a secured tunnel over the Internet — IPsec (IP Security) and SSL
(Secure Sockets Layer). IPsec runs on top of the IP layer and SSL runs over HTTP sessions. IPsec provides
better data throughput and SSL offers ease of use without the need of VPN client applications. The
Wireless-N Gigabit Security Router supports IPsec VPN for maximum throughput on data security.
VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private
network. Using industry standard encryption and authentication techniques—IPsec, short for IP
Security—the VPN creates a secure connection that, in effect, operates as if you were directly connected to
your local network. Virtual Private Networking can be used to create secure networks linking a central
office with branch offices, telecommuters, and/or professionals on the road (travelers can connect to a VPN
Router using any computer
encryption: encoding data transmitted in a network ip (internet protocol): a protocol used to send data
over a network software: instructions for the computer
• VPN Router to VPN Router
• Computer (using the Linksys VPN client software) to VPN Router
The VPN Router creates a “tunnel” or channel between two endpoints, so that data
transmissions between them are secure. A computer with the Linksys VPN client
software can be one of the two endpoints (refer to “Appendix
C: Using the Linksys QuickVPN Software for Windows 2000 or XP”). If you choose not
to run the VPN client software, any computer with the built-in IPsec Security Manager
(Microsoft 2000 and XP) allows the VPN Router
VPN Router to VPN Router
An example of a VPN Router-to-VPN Router VPN would be as follows. At home, a telecommuter uses his
VPN Router for his always-on Internet connection. His router is configured with his office's VPN settings.
When he connects to his office's router, the two routers create a VPN tunnel, encrypting and decrypting
data. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the telecommuter now has a
secure connection to the central office's network, as if he were physically connected. For more information,
refer to “Appendix C: Configuring a Gateway-to-Gateway IPsec Tunnel.”
Computer (using the Linksys VPN client software) to VPN Router
The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling
businesswoman dials up her ISP. Her notebook computer has the Linksys VPN client software, which is
configured with her office's IP address. She accesses the Linksys VPN client software and connects to the
VPN Router at the central office. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the
businesswoman now has a secure connection to the central office's network, as if she were physically
connected.
For additional information and instructions about creating your own VPN, please visit Linksys’s website at
www.linksys.com. You can also refer to “Appendix B: Using the Linksys QuickVPN Software for
Windows 2000 or XP” and “Appendix C: Configuring a Gateway-to-Gateway IPsec Tunnel.”

Chapter 5: Connecting the Router
Overview
To set up your network, you will do the following:
•
Connect the Router to one of your PCs according to the instructions in this chapter.
•
By default, Windows 98, 2000, Millennium, and XP computers are set to obtain an IP
address automatically, so unless you have changed the default setting, then you will not need to configure
your PCs. (If you do need to configure your PCs, refer to Windows Help for more information.)
•
Set up and configure the Router with the setting(s) provided by your Internet Service
Provider (ISP) according to “Chapter 6: Setting Up and Configuring the Router.”
The installation technician from your ISP should have left the setup information with you after installing
your broadband connection. If not, you can call your ISP to request the information. Once you have the
setup information for your specific type of Internet connection, then you can begin installation and setup of
the Router.

Chapter 6: Setting Up and
Configuring the Router
Overview
The Wireless Router has been designed to be functional right out of the box with the default settings.
However, if you'd like to change these settings, the Wireless Router can be configured through your web
browser with the Web-based Utility. This chapter explains how to use the Utility to perform the most basic
settings.
The Utility can be accessed via web browsers, such as Microsoft Internet Explorer or Mozilla Firefox
through the use of a computer that is networked with the Wireless Router.
Basic Setup
For a basic network setup, most users only need to use the following screens of the Utility:
•Setup->WAN Click the Setup tab and then select the WAN screen. Select the appropriate Internet
Connection Type according to your ISP if connecting your WAN port to the WAN (DSL or cable modem).
Otherwise, most cases can leave the default setting to get a WAN port IP address from a DHCP server.
•Setup->Advanced Routing Click the Setup tab and then select the Advanced Routing screen. If you are
connecting the Router to the Internet, leave the default setting. Otherwise, choose the Intranet Router
Operation Mode to disable NAT (Network Address Translation).
•Management Click the Administration tab and then select the Management screen. Change the access
password for the Router’s Web-based Utility. The default username and password are admin.
Most users will also customize their wireless settings:
•Wireless On the Wireless screen, change the default SSID on the Basic Settings Tab. Select the level of
security under the Security Settings Tab and complete the options for the selected security mode. When
the appropriate security mode is configured, disable SSID Broadcast on the Basic Settings Tab.
There are two ways to connect to your Wireless Router for the first time.
1. Connect your PC to one of the four LAN ports on the Router. (Refer to "Chapter 5: Connecting the
Router.") Then, configure your PC to obtain IP address automatically through a DHCP server.
2. Although it is not recommended, you can also connect your PC wirelessly to the Wireless Router. Then,
configure the wireless interface of your PC to obtain IP address automatically through a DHCP server.
It is not recommended, because you can easily lose your connection through wireless configuration
changes.
To access the Web-based Utility of the Router:
•Launch a web browser, such as Internet Explorer or Mozilla Firefox, and enter the Router’s default IP
address, 192.168.1.1, in the Address field. Press the Enter key.
•A screen will appear asking you for your User name and Password. Enter admin in the User Name field,
and enter your password (default password is admin) in the Password field. Then click the OK button.
How to Navigate the Utility

255.255.255.0.
IP Reserved for Internal Usage. Enter the reserved IP between 1 and 254.
Server Settings (DHCP)
The Router can be used as your network’s DHCP (Dynamic Host Configuration Protocol)
server, which automatically assigns an IP address to each PC on your network. Unless
you already have one, it is highly recommended that you leave the Router enabled as a
DHCP server.
DHCP Server. DHCP is enabled by default. If you already have a DHCP server on your
network, or you don't want a DHCP server, then select Disable (no other DHCP features
will be available). If you already have a DHCP server on your network, and you want the
Router to act as a Relay for that DHCP Server, select DHCP Relay, then enter the DHCP
Server IP Address.
Starting IP Address. Enter a value for the DHCP server to start with when issuing IP
addresses. This value will automatically follow your local IP address settings. Normally,
you assign the first IP address for the Router (e.g. 192.168.1.1) so that you can assign an
IP address to other devices starting from the 2nd IP address (e.g. 192.168.1.2). The last
address in the subnet is for subnet broadcast (e.g. 192.168.1.255) so that the address
cannot be assigned to any host.
Maximum Number of DHCP Users. Enter the maximum number of PCs that you want
the DHCP server to assign IP addresses to. This number cannot be greater than the
available host addresses in the subnet (e.g. 253 for /24 subnet). In order to determine the
DHCP IP Address range, add the starting IP address (e.g., 100) to the number of DHCP
users.
Client Lease Time. This is the amount of time a DHCP client can keep the assigned IP
address before it sends a renewal request to the DHCP server. The default value is 0,
which actually means one day.
Static DNS 1-3. If applicable, enter the IP address(es) of your DNS server(s).
WINS The Windows Internet Naming Service (WINS) provides name resolution service
(similar to DNS) in Windows networks. If you use a WINS server, enter that server’s IP
Address here. Otherwise, leave this blank.
Static IP Mapping
Static IP Mapping is used to bind a specific IP address to a specific MAC address. This
helps external (WAN) users to access LAN servers that are advertised through NAPT port
forwarding. You can define up to 50 entries.
Static IP Address Enter the IP address to be mapped.
MAC Address Enter the MAC address to be mapped.
Host Name Enter the host name to be mapped.
Click Add to create the entry and add it to the list. To modify an existing entry, select it
from the list, edit the appropriate field(s), and then click Modify. To delete an entry,
select it and click Remove.

LAN must be assigned (fixed) Internet IP addresses. In Intranet Router mode, the NAT
mechanism is disabled.
Dynamic Routing
The Router's dynamic routing feature can be used to automatically establish a routing
table through a database exchange with peer routers (running the same routing protocol).
The Router supports RIP (Routing Information Protocol) versions 1 & 2.
RIP (Routing Information Protocol. The Router, using the RIP protocol, calculates the
most efficient route for the network’s data packets to travel between the source and the
destination based upon the shortest paths.
RIP Send Packet Version. Choose the version of RIP packets you want to send to peers:
RIPv1 or RIPv2. This should match the version supported by other Routers on your LAN.
RIP Recv Packet Version. Choose the version of RIP packets you want to receive from peers:
RIPv1 or RIPv2. This should match the version supported by other Routers on your LAN.
Static Routing
Sometimes you will prefer to use static routes to build your routing table instead of using
dynamic routing protocols. Static routes do not require CPU resources to exchange
routing information with a peer router. You can also use static routes to reach peer routers
that do not support dynamic routing protocols. Static routes can be used together with
dynamic routes. Be careful not to introduce routing loops in your network.
To set up static routing, you should add route entries in the routing table that tell the
Router where to forward packets to specific IP destinations.
Enter the following data to create a static route entry:
1.
2.
3.
4.
5.
Select Set Number. Select the set number (routing table entry number) that you wish to view or
configure. If necessary, click Delete This Entry to clear the entry.
Destination IP Address. Enter the network address of the remote LAN segment. For a standard Class
C IP domain, the network address is the first three fields of the Destination LAN IP; the last field
should be zero.
Subnet Mask. Enter the Subnet Mask used on the destination LAN IP domain. For Class C IP
domains, the Subnet Mask is 255.255.255.0.
Gateway. If this Router is used to connect your network to the Internet, then your gateway IP is the
Router’s IP Address. If you have another router handling your network’s Internet connection, enter the
IP Address of that router instead.
Hop Count. This value gives the number of nodes that a data packet passes through before reaching its
destination. A node is any device on the network, such as switches, PCs, etc. The maximum hop count
value is 16.
Show Routing Table button. Click this button to show the routing table established
either through dynamic or static routing methods.

IP Mode
IPv4 Only. Select this option to use IPv4 on the Internet and local network.
Dual-Stack IP. Select this option to use IPv4 on the Internet and IPv4 and IPv6 on the
local network. Then select how the IPv6 hosts will connect to the Internet:
•
NAPT-PT This allows an IPv6-only host on your LAN to connect to IPv4-only hosts on the WAN
using address translation and protocol-translation (per RFC2766).
•
6to4 This allows your IPv6 network to connect to other IPv6 networks via tunnels through IPv4 (per
RFC3056). The remote router also needs to support 6to4 as well. Since the tunnel can be
automatically formed based on traffic, there is no limit on how many tunnels you can have.
6to4 Gateway Access Control By default, this route allows 6to4 connections to or from any other
6to4 gateway. By enabling this Access Control, you can have a better control which IPv6 clouds this
router is connecting to. A list of IP addresses can be entered in the Access List. Those should be the
IPv4 addresses of the remote 6to4 gateways.
•
Permit following sites: Allow only a limited set of 6to4 gateways to establish tunnel with our
router. Up to 20 sites can be configured and they can send traffic simultaneously.
•
Block following sites: Prevent a limited set of 6to4 gateways from establishing tunnels with our
router. Up to 20 sites can be configured.
Static 6to4 DNS entry: Allow users to configure static DNS entry to map hostname to IPv6 address.
This will provide a convenient way for users to access remote IPv6 hosts.

Advanced Wireless Settings
This screen allows you to configure the advanced settings for the Wireless Router. The
Wireless-N Router adopts several new parameters to adjust the channel bandwidth and
guard intervals to improve the data rate dynamically. Linksys recommends to let your
Wireless Router automatically adjust the parameters for maximum data throughput.
Advanced Settings
You can change the following advanced parameters (some only for Wireless-N) for this
Wireless Router.
Channel Bandwidth. You can select the channel bandwidth manually for Wireless-N
connections. When it is set to 20MHz, only the 20MHz channel is used. When it is set to
40MHz, Wireless-N connections will use 40MHz channel but Wireless-B and Wireless-G
will still use 20MHz channel. When it is set to Auto, it allows wireless clients to negotiate
the bandwidth to use. The default is 20MHz.
Guard Interval. You can select the guard interval manually for Wireless-N connections.
The two options are Short (400ns) and Long (800ns). The default is Auto.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode function boosts the
Wireless Router’s ability to catch all wireless transmissions, but will severely decrease
performance. Keep the default setting, Auto, so the Wireless Router can use this feature
as needed, when the Wireless-N/G products are not able to transmit to the Wireless
Router in an environment with heavy 802.11b traffic. Select Disabled if you want to
permanently disable this feature.
Beacon Interval. This value indicates the frequency interval of the beacon. A beacon is
a packet broadcast by the Wireless Router to keep the network synchronized. A beacon
includes the wireless networks service area, the Wireless Router address, the Broadcast
destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic
Indicator Message (TIM). The default is 100 ms.
DTIM Interval. This value indicates how often the Wireless Router sends out a Delivery
Traffic Indication Message (DTIM). Lower settings result in more efficient networking,
while preventing your PC from dropping into power-saving sleep mode. Higher settings
allow your PC to enter sleep mode, thus saving power, but interferes with wireless
transmissions. The default is 1 ms.
RTS Threshold. This setting determines how large a packet can be before the Wireless
Router coordinates transmission and reception to ensure efficient communication. This
value should remain at its default setting of 2346. If you encounter inconsistent data flow,
only minor modifications are recommended.
Change these settings as described here and click Save Settings to apply your changes, or
click Cancel Changes to cancel your changes. Help information is displayed on the
right-hand side of the screen, and click More for additional details.
VLAN & QoS
This screen allows you to configure the Qos and VLAN settings for the Access Point. The
QoS (Quality of Service) feature allows you specify priorities for different traffic. Lower
priority traffic will be slowed down to allow greater throughput or less delay for high
priority traffic. The 802.1Q VLAN feature is allowing traffic from different sources to be
segmented. Combined with the multiple SSID feature, this provides a powerful tool to
control access to your LAN
VLAN
Enabled/Disabled VLAN. You can enabled this feature only if the hubs/switches on your
LAN support the VLAN standard.
AP Management VLAN. Define the VLAN ID used for management.
VLAN ID. Enter the VLAN ID.
QoS
U-APSD(WMM Power Save). Select Enabled or Disabled as required.
WMM. Wi-Fi Multimedia is a QoS feature defined by WiFi Alliance before IEEE
802.11e was finalized. Now it is part of IEEE 802.11e. When it is enabled, it provides
four priority queues for different types of traffic. It automatically maps the incoming
packets to the appropriate queues based on QoS settings (in IP or layer 2 header). WMM
provides the capability to prioritize traffic in your environment. The default is Enabled.
Change these settings as described here and click Save Settings to apply your changes, or
click Cancel Changes to cancel your changes. Help information is displayed on the
right-hand side of the screen.

Firewall
The Firewall Tab allows you to configure software security features like SPI (Stateful
Packet Inspection) Firewall, IP based Access List, restriction LAN users on Internet
(WAN port) access, and NAPT (Network Address Port Translation) Settings (only works
when NAT is enabled) to limited services to specific ports.
Note that for WAN traffic, NAPT settings are applied first, then it will pass the SPI
Firewall settings, followed by IP based Access List (which requires more CPU power).
Basic Settings
Firewall: SPI (Stateful Packet Inspection) Firewall, when you enable this feature, the
Router will perform deep packet inspection on all the traffic going through the Router
and drop the packets that do not follow the pre-defined protocol behavior. The default is
Enable.
DoS Protection: When enabled, the Router will prevent DoS (Denial of Service) attacks
coming in from the Internet. DOS attacks are making your Router’s CPU busy such that
it cannot provide services to regular traffic. The default Is Enable.
Block WAN Request: When enabled, the Router will ignore PING Request from the
Internet so it seems to be hidden. The default is Enable.
Remote Management: When enabled, the Router will allow the Web-based Utility to be
accessed from the Internet. The default is Disable.
Multicast Pass-through: When enabled, the Router will allow IP Multicast traffic to
come in from the Internet. The default is Disable.
SIP Application Layer Gateway When this feature is enabled, the SIP Application
Layer Gateway (ALG) allows Session Initiation Protocol (SIP) packets (used for Voice
over IP) to traverse the NAT firewall. This feature can be disabled if the VoIP service
provider is using other NAT traversal solutions such as STUN, TURN, and ICE.
Block. Select the Web features that you wish to restrict. All those features could place
security concern to your PCs on the LAN side. You have to balance your needs on those
applications and security. The default is unselected.

IP Based ACL
This screen shows a summary of configured IP based Access List. The Access List is used
to restrict traffic going through the Router either from WAN or LAN port. There are two
ways to restrict data traffic. You can block specific types of traffic according to your ACL
definitions. Or you can allow only specific types of traffic according to your ACL
definition. The ACL rules will be read according to its priority. If there is a match for a
packet, the action will be taken and following lower priority rules will not be checked
against this packet.
Note that the higher the number of rules that need to be checked against packets, the
lower the throughput. Use ACL rules with caution.
There are two default rules in the table that cannot be deleted. The first rule will allow all
traffic coming in from LAN port to pass the Router. The second rule will allow all traffic
coming in from WAN port. These two rules have the lowest priority, so without adding
any user defined rules, all the packets can be passed through from both WAN and LAN
sides.
The rule will be enabled when the Enable button is checked, and when Date and Time are
matched. If any of conditions are not met, the rule will not be used to check against
packets.
The following are descriptions on each of the fields in the ACL Table:
Page Selections: You can select specific page of ACL list from the drop-down menu to
be displayed. Or you can navigate them page by page through Previous Page and Next
Page button.
Priority: This defines the order on which rule is checked against first. The smaller
number has higher priority. The default rules will always be checked last.
Enable: This tells the Router if the rule is active or not. You can have rules defined in the
ACL Table but in an inactive state. The administrator can decide on when to enable
specific ACL rules manually.
Action: This defines how the rule is to affect the traffic. It can be either Allow or Deny.
If the rule is matched and the action is Allow, the packet will be forwarded. If the rule is
matched and the action is Deny, the packet will be dropped.
Service: This is the service(s) to which the rule applies.
Source Interface: Select LAN, WAN, or ANY interface.
Source: This is the source IP address, which can be one specific IP address, ANY (all IP
addresses), a range of IP addresses, or a specific IP subnet.
Destination: This is the destination IP address, which can be one specific IP address,
ANY (all IP addresses), a range of IP addresses, or a specific IP subnet.
Time: Displays the time period this rule will be enabled (used together with Date). It can
be set to Any Time.

Single Port Forwarding
This is one of the NAPT (Network Address Port Translation) feature. Use the Single Port
Forwarding screen when you want to open specific services (that use single port). This
allows users on the Internet to access this server by using the WAN port address and the
matched external port number. When users send these types of request to your WAN port
IP address via the Internet, the NAT Router will forward those requests to the appropriate
servers on your LAN.
Application. Enter the name of the application you wish to configure.
External Port. This is the port number used by the service or Internet application.
Internet users must connect using this port number. Check with the software
documentation of the Internet application for more information.
Internal Port. This is the port number used by the Router when forwarding Internet
traffic to the PC or server on your LAN and is usually the same as the External Port
number. If it is different, the Router performs a Port Translation, so that the port number
used by Internet users is different from the port number used by the server or Internet
application.
For example, you could configure your Web Server to accept connections on both port 80
(standard) and port 8080. Then, enable Port Forwarding, set the External Port to 80 and
the Internal Port to 8080. Now, any traffic from the Internet to your Web server will be
using port 8080, even though the Internet users used the standard port, 80. (Users on the
local LAN can and should connect to your Web Server using the standard port 80.)
Protocol. Select the protocol used for this application, TCP or UDP.
IP Address. For each application, enter the IP address of the PC running the specific

Port Range Forwarding
This is one of the NAPT (Network Address Port Translation) features. The Port Range
Forwarding screen allows you to set up public services on your network, such as web
servers, ftp servers, e-mail servers, or other specialized Internet applications that use one
or multiple port numbers (e.g. video conference). The port numbers being used will not
change while forwarding to the local network. This allows users on the Internet to access
this server by using the WAN port IP address and the pre-defined port numbers. When
users send these types of requests to your WAN port IP address via the Internet, the NAT
Router will forward those requests to the appropriate servers on your LAN.
Application. Enter the name of the application you wish to configure.
Start. This is the beginning of the port range. Enter the beginning of the range of port
numbers (external ports)
used by the server or Internet application. Check with the software documentation of the
Internet application for more information if necessary.
End. This is the end of the port range. Enter the end of the range of port numbers
(external ports) used by the server or Internet application. Check with the software
documentation of the Internet application for more information if necessary.
Protocol. Select the protocol(s) used for this application, TCP and/or UDP.
IP Address. For each application, enter the IP address of the PC running the specific
application.
Enabled. Select Enabled to enable port range forwarding for the relevant application.

Port Range Triggering
This is one of the NAPT (Network Address Port Translation) feature. Port Range
Triggering is used for special applications that can request a port to be opened on demand.
For this feature, the Wireless Router will watch outgoing packets for specific port
numbers. This will trigger the Wireless Router to allow the incoming packets within the
specified forwarding range and forward those packets to the triggering PC. One of the
example applications is QuickTime. It would use port 1000 for outgoing packets and
2000 for incoming packets.
Application. Enter the name of the application you wish to configure.
Triggered Range. For each application, list the triggered port number range. These are
the ports used by outgoing traffic. Check with the Internet application documentation for
the port number(s) needed. In the first field, enter the starting port number of the
Triggered Range. In the second field, enter the ending port number of the Triggered
Range.
Forwarded Range. For each application, list the forwarded port number range. These are
the ports used by incoming traffic. Check with the Internet application documentation for
the port number(s) needed. In the first field, enter the starting port number of the
Forwarded Range. In the second field, enter the ending port number of the Forwarded
Range.
Enabled. Select Enabled to enable port range triggering for the relevant application.
