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.
This user guide will give you all the information you need to connect, set up, and configure your
Router.

Networking and Security Basics
An Introduction to LANs
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 IP address among all the users.
The Router’s Network Address Port Translation (NAPT or NAT) technology protects your
network of PCs so users 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 Internet applications,
and, if allowed, it will forward the packet to the 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.

Networking and Security Basics
The Use of IP Addresses
Example network
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.
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.”
NOTE: 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.
There are two ways of assigning IP addresses to your network devices.
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.
WRVS4400N User Guide

Networking and Security Basics
The Use of IP Addresses
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.”

Networking and Security Basics
The Intrusion Prevention System (IPS)
The Intrusion Prevention System (IPS)
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 Scenarios
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 P2P (peer to peer) and IM (instant messaging) control allows the system administrator to
prevent network users from using those protocols to communicate with people over the
Internet. This helps the administrators to set up company policies on how to use their Internet
bandwidth wisely.
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 1.3.8 and with a total of 1101 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.

Why do I need a VPN?
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 data to a new destination. Even though the data is not
received by its intended recipient, it appears that way to the person sending the data.
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

Planning Your Virtual Private Network (VPN)
What is a VPN?
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 with the
Linksys VPN client software.)
NOTE: You must have at least one VPN Router on one end
of the VPN tunnel. At the other end of the VPN tunnel, you
must have a second VPN Router or a computer with the
Linksys VPN client
There are two basic ways to create a VPN connection:
•
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 to create a VPN
tunnel using IPsec (refer to “Appendix C: Configuring IPsec between a Windows 2000 or XP PC
and the Router”). Other versions of Microsoft operating systems require additional, third-party
VPN client software applications that support IPsec to be installed.

Planning Your Virtual Private Network (VPN)
What is a VPN?
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.”
VPN Router to VPN Router
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.

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
Router Operation Mode to disable NAT (Network Address Translation).
•

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.
How to Access the Web-based Utility
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

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—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) performs name resolution function
(similar to DNS) in the Windows network environment. It can help you to determine the IP
address of a remote Windows PC from its computer name. If you have a WINS server, enter that

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
Some ISPs require 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. 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.
2. 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.
3. 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.
4. 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.
5. Hop Count (max. 15)—Gives the number of routers that a data packet passes through
before reaching its destination. It is used to define the priority on which route to use if there
is a conflict between a static route and dynamic route.
Show Routing Table button—Click this button to show the routing table established either
through dynamic or static routing methods.

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:

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—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—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 and/or UDP.
IP Address—For each application, enter the IP address of the PC running the specific server
application.

Keying Mode—The router supports both IKE with Preshared Key (automatic) and Manual
key management. When choosing automatic key management, IKE (Internet Key Exchange)
protocols are used to negotiate key material for SA. If manual key management is selected, no
key negotiation is needed. Basically, manual key management is used in small static
environments or for troubleshooting purpose. Notice that both sides must use the same Key
Management method.
Encryption—The Encryption method determines the length of the key used to encrypt/
decrypt ESP packets. 3DES is supported. Notice that both sides of the VPN tunnel must use the
same Encryption method.
Authentication—Authentication determines a method to authenticate the ESP packets. Either
MD5 or SHA1 may be selected. Both sides of the VPN tunnel must use the same Authentication
method.
•
MD5—A one way hashing algorithm that produces a 128-bit digest.
•
SHA1—A one way hashing algorithm that produces a 160-bit digest.
Preshared Key— IKE uses the Pre-shared Key field to authenticate the remote IKE peer. Both
character and hexadecimal value are acceptable in this field. for example; "My_@123" or
"0x4d795f40313233". Both sides must use the same Pre-shared Key.
Key Lifetime—Specifies the lifetime of the IKE generated key. If the time expires, a new key will
be renegotiated automatically. The Key Lifetime may range from 1081 to 86400 seconds. The
default value for Phase 1 is 28800 seconds, and default value for Phase 2 is 3600 seconds
Group— For Diffie-Hellman key negotiation. There are 3 groups available for ISAKMP SA
establishment, 768-bit, 1024-bit, 1536-bit represent different bits used in Diffie-Hellman mode
operation. The default value is Group 768-bit.

The Layer 2 Switch Tab provides configurations to the layer 2 switching features on the four
Ethernet LAN ports of the Wireless Router. They include VLAN, port configuration, cable
diagnostics, and RADIUS authentication.
VLAN
VLAN Configuration
VLANs are logical subgroups of a Local Area Network (LAN) created via software rather than
defining a hardware solution. VLANs combine user stations and network devices into a single
domain regardless of the physical LAN segment to which they are attached. VLANs allow
WRVS4400N User Guide
94
Setting Up and Configuring the Router
L2 Switch Tab
network traffic to flow more efficiently within subgroups. VLANs managed through software
reduce the amount of time in which network changes are implemented.
VLANs have no minimum number of ports, and can be created per unit, per device, per stack, or
any other logical connection combination, as VLANs are software based and not defined by
physical attributes.
VLANs function at layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 router is needed
to allow traffic flow between VLANs. Layer 3 routers identify segments and coordinate with
VLANs.
VLANs are broadcast and multicast domains. Broadcast and multicast traffic is transmitted only
in the VLAN in which the traffic is generated.
This device supports up to 4 VLANs, including the default VLAN.
VLAN ID—The VLAN ID number. This can be any number from 2 to 3290, or from 3293 to 4094.
(VLAN ID 1 is reserved for the default VLAN, which is used for untagged frames received on the
interface. VLAN IDs 3291-3292 are reserved and cannot be used.) To create a VLAN, enter the ID
number and click Add VLAN.
VLAN ID Range—To create multiple VLANs with a range of ID numbers, enter the starting and
ending ID numbers and click Add Range.
Delete Selected VLAN—To delete a VLAN, select it form the VLAN list and click Delete Selected
VLAN.

individual VLANs). It requires users to specify the port mode for each port. The "acceptable
frame type" and "PVID" options are for "General" port mode only
Port Mode—select one of the three modes:
•
Access—All frames are untagged coming in or going out of the switch port. Wireless
port can be set to this mode only.
•
Trunk—All frames are tagged coming in or going out of the switch except for VLAN ID 1
(called native VLAN or default VLAN in Cisco)

–
Acceptable Ingress Frame Type—All Frames: all the incoming frames are
acceptable.
Tagged Only: only tagged incoming frames are acceptable
–
Ingress Filtering—Check the VLAN ID on the incoming packet. If the port is a
member of this VLAN, accept the frame. Otherwise, drop it. If not enabled, all frames
are accepted.
PVID—The VLAN ID of the default (untagged) VLAN
The second section is per VLAN settings to be used with each port. It requires users to specify
each VLAN to be tagged, untagged, or excluded on the specific port.
•
VLAN— Select a VLAN ID to be configured
•
VLAN NAME— VLAN description (read-only) to help user identify this VLAN
•
Tagged— Egress frames from this port is tagged for this VLAN
•
Untagged—Egress frames from this port is untagged for this VLAN
•
Excluded—The port does not participate in this VLAN at all
For Access port, the available options are either untagged or excluded. Therefore, wireless port
can set to one of these two modes for each VLAN. Only one of the VLAN ID can be selected
(untagged).
For Trunk port, the options are tagged or excluded for all VLAN IDs except VLAN 1. VLAN 1 must
be untagged.
For General port, the options are tagged or untagged for PVID; tagged or excluded for all other
VLAN IDs.
The third section is a summary of VLAN subscriptions on each port. "U" means untagged while
"T" means tagged.

Common Problems and Solutions
Troubleshooting
This appendix provides solutions to problems that may occur during the installation and
operation of the Router. Read the descriptions below to help solve your problems. If you can't
find an answer here, check the Linksys website at www.linksys.com.
Common Problems and Solutions
I need to set a static IP address on a PC.
The Router, by default, assigns an IP address range of 192.168.1.100 to 192.168.1.149 using the
DHCP server on the Router. To set a static IP address, you can only use the ranges 192.168.1.2 to
192.168.1.99 and 192.168.1.150 to 192.168.1.254. Each PC or network device that uses TCP/IP
must have a unique address to identify itself in a network. If the IP address is not unique to a
network, Windows will generate an IP conflict error message. You can assign a static IP address
to a PC by performing the following steps:
For Windows 98 and Millennium:
1. Click Start, Setting, and Control Panel. Double-click Network.
2. In The following network components are installed box, select the TCP/IP-> associated with
your Ethernet adapter. If you only have one Ethernet adapter installed, you will only see one
TCP/IP line with no association to an Ethernet adapter. Highlight it and click the Properties
button.
3. In the TCP/IP properties window, select the IP address tab, and select Specify an IP
address. Enter a unique IP address that is not used by any other computer on the network
connected to the Router. You can only use an IP address in the ranges 192.168.1.2 to
192.168.1.99 and 192.168.1.151 to 192.168.1.254. Make sure that each IP address is unique
for each PC or network device.
4. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1, which is the
default IP address of the Router. Click the Add button to accept the entry.
5. Click the DNS tab, and make sure the DNS Enabled option is selected. Enter the Host and
Domain names (e.g., John for Host and home for Domain). Enter the DNS entry provided by
your ISP. If your ISP has not provided the DNS IP address, contact your ISP to get that
information or go to its website for the information.
6. Click the OK button in the TCP/IP properties window, and click Close or the OK button for
the Network window.
7. Restart the computer when asked.
For Windows 2000:
1. Click Start, Settings, and Control Panel. Double-click Network and Dial-Up Connections.
2. Right-click the Local Area Connection that is associated with the Ethernet adapter you are
using, and select the Properties option.

I am not getting an IP address on the Internet with my Internet connection.
1. Refer to “I want to test my Internet connection” to verify that you have connectivity.
2. If you need to register the MAC address of your Ethernet adapter with your ISP, please see
“Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter.” If you
need to clone the MAC address of your Ethernet adapter onto the Router, see the MAC
Address Clone section of “Chapter 6: Setting Up and Configuring the Router” for details.
3. Make sure you are using the right Internet settings. Contact your ISP to see if your Internet
connection type is DHCP, Static IP Address, or PPPoE (commonly used by DSL consumers).
Please refer to the Basic Setup section of “Chapter 6: Setting Up and Configuring the
Router” for details on Internet Connection Type settings.
4. Make sure you use the right cable. Check to see if the Internet LED is solidly lit.
5. Make sure the cable connecting from your cable or DSL modem is connected to the
Router’s Internet port. Verify that the Status page of the Router’s Web-based Utility shows a
valid IP address from your ISP.
6. Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds, and then turn on
the Router, cable/DSL modem, and computer. Check the System Summary tab of the

Common Problems and Solutions
1. Refer to “Problem #2, I want to test my Internet connection” to verify that your computer is
properly connected to the Router.
2. Refer to “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” to
verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS.
3. Set a static IP address on your system; refer to “Problem #1: I need to set a static IP address.”
4. Refer to “Problem #10: I need to remove the proxy settings or the dial-up pop-up window
(for PPPoE users).”
I can’t get my Virtual Private Network (VPN) to work through the Router.
Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the
Router, and go to the VPN => VPN Pass Through tab. Make sure you have IPsec passthrough
and/or PPTP passthrough enabled.
VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50)
authentication will work fine. At least one IPSec session will work through the Router; however,
simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs.
VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible
with the Router. AH has limitations due to occasional incompatibility with the NAT standard.
Change the IP address for the Router to another subnet to avoid a conflict between the VPN IP
address and your local IP address. For example, if your VPN server assigns an IP address
192.168.1.X (X is a number from 1 to 254) and your local LAN IP address is 192.168.1.X (X is the
same number used in the VPN IP address), the Router will have difficulties routing information
to the right location. If you change the Router’s IP address to 192.168.2.1, that should solve the
problem. Change the Router’s IP address through the Basic Setup tab of the Web-based Utility.
If you assigned a static IP address to any computer or network device on the network, you need
to change its IP address accordingly to 192.168.2.Y (Y being any number from 1 to 254). Note
that each IP address must be unique within the network.
Your VPN may require port 500/UDP packets to be passed to the computer that is connecting
to the IPSec server. Refer to “Problem #7, I need to set up online game hosting or use other
Internet applications” for details.
Check the Linksys website at www.linksys.com for more information.
I need to set up a server behind my Router.
To use a server like a web, ftp, or mail server, you need to know the respective port numbers
they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and
port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can
get more information by viewing the documentation provided with the server you installed.
Follow these steps to set up port forwarding through the Router’s Web-based Utility. We will be
setting up web, ftp, and mail servers.

Common Problems and Solutions
1. Access the Router’s Web-based Utility by going to http://192.168.1.1 or the IP address of
the Router. Go to the Firewall => Single Port Forwarding tab.
2. Enable one of the pre-defined applications in the Table or you can add or modify existing
entries for your application.
3. Enter the IP Address of the server that you want the Internet users to access. For example, if
the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the
field provided. Check “Appendix E: Finding the MAC Address and IP Address for Your

I need to set up online game hosting or use other Internet applications.
If you want to play online games or use Internet applications, most will work without doing any
port forwarding or DMZ hosting. There may be cases when you want to host an online game or
Internet application. This would require you to set up the Router to deliver incoming packets or
data to a specific computer. This also applies to the Internet applications you are using. The
best way to get the information on what port services to use is to go to the website of the
online game or application you want to use. Follow these steps to set up online game hosting
or use a certain Internet application:
1. Access the Router’s Web-based Utility by going to http://192.168.1.1 or the IP address of
the Router. Go to the Firewall => Port Range Forwarding tab.
2. Enter the Service Application Name, Range of Port used by this Application, and Layer 4
Protocol used by this Application to the Table.
3. Enter the IP Address of the server that you want the Internet users to access. For example, if
the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the

I can’t get the Internet game, server, or application to work.
If you are having difficulties getting any Internet game, server, or application to function
properly, consider exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting.
This option is available when an application requires too many ports or when you are not sure
which port services to use. Make sure you disable all the forwarding entries if you want to
successfully use DMZ hosting, since forwarding has priority over DMZ hosting. (In other words,
data that enters the Router will be checked first by the forwarding settings. If the port number
that the data enters from does not have port forwarding, then the Router will send the data to
whichever PC or network device you set for DMZ hosting.) Follow these steps to set DMZ
hosting:
1. Access the Router’s Web-based Utility by going to http://192.168.1.1 or the IP address of
the Router. Go to the Firewall => Single Port Forwarding tab.
2. Disable or remove the entries you have entered for forwarding. Keep this information in
case you want to use it at a later time.
3. Go to the Setup => DMZ tab.
4. Enter the Ethernet adapter’s IP address of the computer you want exposed to the Internet.
This will bypass the NAT security for that computer. Please refer to “Appendix E: Finding the
MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.
5. Once completed with the configuration, click the Save Settings button.
I forgot my password, or the password prompt always appears when saving settings to the
Router.
Reset the Router to factory defaults by pressing the Reset button for ten seconds and then
releasing it. If you are still getting prompted for a password when saving settings, then perform
the following steps:
1. Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the
Router. Enter the default password admin, and click the Administration => Management
tab.
2. Enter the old password in the Old Password field.
3. Enter a different password in the New Password field, and enter the new password in the

I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.
If you have proxy settings, you need to disable these on your computer. Because the Router is
the gateway for the Internet connection, the computer does not need any proxy settings to
gain access. Please follow these directions to verify that you do not have any proxy settings and
that the browser you use is set to connect directly to the LAN.
For Microsoft Internet Explorer 5.0 or higher:
1. Click Start, Settings, and Control Panel. Double-click Internet Options.
2. Click the Connections tab.
3. Click the LAN settings button and remove anything that is checked.
4. Click the OK button to go back to the previous screen.
5. Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE
users.
For Netscape 4.7 or higher:
1. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies.
2. Make sure you have Direct connection to the Internet selected on this screen.
3. Close all the windows to finish.
To start over, I need to set the Router to factory default.
Hold the Reset button for up to 30 seconds and then release it. This will return the password,
forwarding, and other settings on the Router to the factory default settings. In other words, the
Router will revert to its original factory configuration.

Frequently Asked Questions
What is the maximum number of IP addresses that the Router will support?
The Router will support up to 253 IP addresses if the subnetmask is set to 255.255.255.0.
Is IPSec Passthrough supported by the Router?
Yes, enable or disable IPSec Passthrough on the VPN => VPN Pass Through tab.
Where is the Router installed on the network?
In a typical environment, the Router is installed between the cable/DSL modem and the LAN.
Plug the Router into the cable/DSL modem’s Ethernet port.
Does the Router support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the global standard
for communications. IPX, a NetWare communications protocol used only to route messages
from one node to another, and AppleTalk, a communications protocol used on Apple and
Macintosh networks, can be used for LAN to LAN connections, but those protocols cannot
connect from the Internet to the LAN.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one
public address that is sent out to the Internet. This adds a level of security since the address of a
PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows
the Router to be used with low cost Internet accounts, such as DSL or cable modems, when
only one TCP/IP address is provided by the ISP. The user may have many private addresses
behind this single address provided by the ISP.
Does the Router support any operating system other than Windows 98, Millennium, 2000, or
XP?
WRVS4400N User Guide

Frequently Asked Questions
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or
troubleshooting of any non-Windows operating systems.
I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to
do?
If you have a dedicated Unreal Tournament server running, you need to create a static IP for
each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP
address of the server. You can also use a port forwarding range of 7777 to 27900. If you want to
use the UT Server Admin, forward another port (8080 usually works well but is used for remote
admin. You may have to disable this.), and then in the [UWeb.WebServer] section of the
server.ini file, set the ListenPort to 8080 (to match the mapped port above) and ServerName to
the IP assigned to the Router from your ISP.
Can multiple gamers on the LAN get on one game server and play simultaneously with just
one public IP address?
It depends on which network game or what kind of game server you are using. For example,
Unreal Tournament supports multi-login with one public IP.
How do I get Half-Life: Team Fortress to work with the Router?
The default client port for Half-Life is 27005. The computers on your LAN need to have
“+clientport 2700x” added to the HL shortcut command line; the x would be 6, 7, 8, and on up.
This lets multiple computers connect to the same server. One problem: Version 1.0.1.6 won’t let
multiple computers with the same CD key connect at the same time, even if on the same LAN
(not a problem with 1.0.1.3). As far as hosting games, the HL server does not need to be in the
DMZ. Just forward port 27015 to the local IP address of the server computer.
How can I block corrupted FTP downloads?
If you are experiencing corrupted files when you download a file with your FTP client, try using
another FTP program.
The web page hangs; downloads are corrupt, or nothing but junk characters are being
displayed on the screen. What do I need to do?
Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate”
feature of your Ethernet adapter as a temporary measure. (Please look at the Network Control

The Router allows PPTP packets to pass through.
Is the Router cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with the Router.
How many ports can be simultaneously forwarded?
Theoretically, the Router can establish 4,000 sessions at the same time, but you can only
forward 30 ranges of ports.
Does the Router replace a modem? Is there a cable or DSL modem in the Router?
No, this version of the Router must work in conjunction with a cable or DSL modem.
Which modems are compatible with the Router?
The Router is compatible with virtually any cable or DSL modem that supports Ethernet.
What is the maximum number of VPN sessions allowed by the Router?
WRVS4400N User Guide
133
Frequently Asked Questions
The maximum number depends on many factors. At least one IPSec session will work through
the Router; however, simultaneous IPSec sessions may be possible, depending on the specifics
of your VPNs.
How can I check whether I have static or DHCP IP addresses?
Ask your ISP to find out.
How do I get mIRC to work with the Router?
Under the Firewall => Single Port Forwarding tab, set port forwarding to 113 for the PC on
which you are using mIRC.
