Introduction

Thank you for choosing the Cisco WRVS4400N 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. WRVS4400N lets multiple computers in your office share an Internet connection through both wired and wireless connections.

The WRVS4400N wireless router features a built-in 4-Port full-duplex 10/100/

1000 Ethernet switch, which allows you to connect four personal computers directly, or you can connect more hubs and switches to create as big a network as you need.

You can use the WRVS4400N wireless router as an intranet router to aggregate traffic to a company backbone network.

The WRVS4400N wireless router has a built-in access point that supports the latest 802.11n draft specification by IEEE. The WRVS4400N wireless router also supports 802.11g and 802.11b clients in a mixed environment.

The built-in access point can support an 11n data rate of up to 300 Mbps. In addition to 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.

The Cisco WRVS4400N 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. They identify, classify, and stop malicious attack traffic in real time while passing through the WRVS4400N wireless router.

The SPI Firewall provides deep packet inspection to analyze packets in network layer (IP) and transport layer (TCP, UDP) to block illegal packet transactions. You can also use IP based ACL to limit traffic to a specific source, destination and protocol.

Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN Administration Guide 6

Introduction

1

NAPT allows you 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 of the Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN provide consistent voice and video quality throughout your business.

This administration guide gives you all the information you need to connect, set up, and configure your router.

Networking and Security Basics

This chapter describes networking and security basics. It includes the following sections:

An Introduction to LANs, page 8

The Use of IP Addresses, page 9

The Intrusion Prevention System (IPS), page 11

An Introduction to LANs

A router is a network device that connects two networks together.

The router connects your local area network (LAN), or the group of personal computers in your home or office, to the Internet. The router processes and regulates the data that travels between these two networks.

The router’s Network Address Translation (NAT) technology protects your network of personal computers so users on the Internet cannot “see” your personal computers. 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 personal computer on the LAN side.

You can use multiple Cisco WRVS4400N Wireless-N Gigabit Security Routers 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 WRVS4400N wireless router for each subnetwork and you can connect all the WAN ports to a second level router or switch to the Internet.

Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN Administration Guide 8

Networking and Security Basics

The Use of IP Addresses

2

The second level router only forwards data packets through a wired network so you don’t have to use the Cisco WRVS4400N Wireless-N Gigabit Security Router.

You can use any wired router in the Cisco family such as RVS4000 that has 4 LAN ports and 1 WAN port.

The Use of IP Addresses

IP stands for Internet Protocol. Every device in an IP-based network, including personal computers, 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.

A static IP address is a fixed IP address that you assign manually to a personal computer 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 network devices such as server personal computers or print servers.

Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN Administration Guide 9

Networking and Security Basics

The Use of IP Addresses

2

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. These

IP addresses are called dynamic because they are only temporarily assigned to the personal computer or other device. After a certain time period, they expire and may change. If a personal computer 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.

A DHCP server can either be a designated personal computer on the network or another network device, such as the router. By default, the router’s Internet

Connection Type is Obtain an IP automatically (DHCP).

The personal computer 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 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, but PPPoE does not dial a phone number when establishing a connection. It also will provide the router with a dynamic IP address to establish a connection to the Internet.

By default, a DHCP server (on the LAN side) 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, see

Configuring Local Area Network (LAN) Settings, page 52

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 Administration

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 blocked so the router and network seem invisible to the Internet.

Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN Administration Guide 10

Networking and Security Basics

The Intrusion Prevention System (IPS)

2

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 Control List (ACL),

Network Address Port Translation (NAPT), and Virtual Private Network (VPN) to achieve the highest level of security. IPS works by providing real-time detection and prevention as an in-line module in a router.

The WRVS4400N wireless router has hardware-based acceleration for real-time pattern matching for detecting malicious attacks. It actively filters and drops malicious TCP/UDP/ICMP/IGMP packets and can reset TCP connections. This protects your client personal computers and servers running various operating systems including Windows, Linux, and Solaris from network worm attacks.

However, this system does not prevent viruses contained in e-mail attachments.

The P2P (peer to peer) and IM (instant messaging) control allows you 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 personal computer’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.

It is recommended that you update your IPS signature file regularly to thwart new attack types.

The following diagram illustrates a number of IPS scenarios.

Planning Your Virtual Private Network (VPN)

This chapter provides information for planning your VPN and includes the following sections:

Why do I need a VPN?, page 13

What is a VPN?, page 15

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.

Planning Your Virtual Private Network (VPN)

Why do I need a VPN?

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:

MAC Address Spoofing, page 14

Data Sniffing, page 14

Man in the Middle Attacks, page 14

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.

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.

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 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.

Planning Your Virtual Private Network (VPN)

What is a VPN?

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.

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—VPN creates a secure connection that, in effect, operates as if you were directly connected to your local network. VPN 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 Cisco QuickVPN Client software.)

There are two basic ways to create a VPN connection:

• VPN router to VPN router

• Computer (using the Cisco QuickVPN 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 Cisco QuickVPN

Client software can be one of the two endpoints (refer to

Appendix B, “Using

Cisco QuickVPN for Windows 2000, XP, or Vista”

). 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 a Gateway-to-Gateway IPSec Tunnel.”

).

Other versions of Microsoft operating systems require additional, third-party VPN client software applications that support IPSec to be installed.

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 Gatewayto-Gateway IPSec Tunnel.”

Computer to VPN Router

The following is an example of a computer-to-VPN router VPN. In her hotel room, a traveling businesswoman connects to her ISP. Her notebook computer has the

Cisco QuickVPN Client software, which is configured with her office’s IP address.

She accesses the Cisco QuickVPN 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, she now has a secure connection to the central office’s network, as if she were physically connected.

Accessing the Web-Based Utility

There are two ways to connect to your wireless router for the first time:

• Physically connect your personal computer to one of the four LAN ports on the router. Then, configure your personal computer to obtain its IP address automatically from a DHCP server.

• Wirelessly connect your personal computer to the router (not recommended), by configuring the wireless interface of your personal computer to obtain its IP address automatically from a DHCP server.

Server Settings (DHCP)

—Unless you already have a DHCP server, it is highly recommended that you leave the router enabled as a DHCP server.

To use the router as your network’s DHCP (Dynamic Host Configuration

Protocol) server, so that it automatically assigns an IP address to each personal computer on your network, Enable 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 DHCP features will be available).

If you already have a DHCP server on your network, but 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 automatically follows your local IP address settings.

Normally, you would assign the first IP address for the router (for example,

192.168.1.1) so that you can assign an IP address to other devices starting from the 2nd IP address (for example, 192.168.1.2).

The last address in the subnet is for subnet broadcast (for example,

192.168.1.255) so that the address cannot be assigned to any host.

-

Maximum Number of DHCP Users

—Enter the maximum number of personal computers to which you want the DHCP server to assign IP addresses.

This number cannot be greater than the available host addresses in the subnet (for example, 253 for /24 subnet).

In order to determine the DHCP IP address range, add the starting IP address (for example, 100) to the number of DHCP users.

-

Client Lease Time

—Enter the amount of time you want a DHCP client to 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

STEP 3

• To s elect t he operating mode in which the router functions:

Select Gateway to allow all devices on your LAN to share the same WAN

(Internet) IP address, the normal mode of operation—in Gateway mode, the NAT (Network Address Translation) mechanism is enabled.

Select Router to use another router as the Internet Gateway, or to have all personal computers on your LAN assigned (fixed) Internet IP addressesin Intranet Router mode, the NAT mechanism is disabled.

Configure Dynamic Routing if appropriate.

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.

To configure Dynamic Routing, follow these steps: a. Enable RIP (Routing Information Protocol) for the router to use the RIP protocol and calculate the most efficient route for the network’s data packets to travel between the source and the destination, based upon the shortest paths.

b. For RIP Send Packet Version, choose the version of RIP packets you want to send to peers (RIPv1 or RIPv2) to match the version supported by other routers on your LAN.

STEP 4

c. For RIP Recv Packet Version, choose the version of RIP packets you want to receive from peers (RIPv1 or RIPv2) to match the version supported by other routers on your LAN.

Configure Static Routing if necessary:

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. a. To set up static routing, add route entries in the routing table that tell the router where to forward packets to specific IP destinations.

To create a static route entry, provide the following information:

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 (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.

6to4 Tunnel—

Allows your IPv6 network to connect to other IPv6 networks via tunnels through IPv4 (per RFC3056). The remote router also needs to support 6to4. Because the tunnel can be automatically formed based on traffic, there is no limit as to how many tunnels you can have.

6 to 4 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.

Indicates the frequency interval of the beacon. A beacon is a packet broadcast by the router to keep the network synchronized. A beacon includes the wireless networks service area, the 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

—Indicates how often the router sends out a Delivery Traffic

Indication Message (DTIM). Lower settings result in more efficient networking, while preventing your personal computer from dropping into power-saving sleep mode. Higher settings allow your personal computer to enter sleep mode, thus saving power, but interferes with wireless transmissions. The default is 1 ms.

Service) attacks coming in from the Internet. DoS attacks consume most of the router’s resources and as a result they can prevent legitimate traffic from passing through the router. The default Is Enable.

Block WAN Request

—When enabled, the router ignores PING Request from the Internet so it seems to be hidden. The default is Enable.

Remote Management

—When enabled, the router allows the web-based utility to be accessed from the Internet. The default is Disable.

Multicast Pass-through

—When enabled, the router allows IP Multicast traffic to come in from the Internet. The default is Disable.

SIP Application Layer Gateway—

When 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 personal computers on the LAN side.

You have to balance your needs on those applications and security. The default is unselected.

-

Java

—Java is a programming language for websites. If you deny Java, you run the risk of not having access to Internet sites created using this programming language.

-

Cookies

—A cookie is data stored on your personal computer and used by Internet sites when you interact with them, so you may not want to deny cookies.

-

ActiveX

—ActiveX is a Microsoft (Internet Explorer) programming language for websites. If you deny ActiveX, you run the risk of not having access to Internet sites using this programming language. Also, Windows

Update uses ActiveX, so if this is blocked, Windows Update does not work.

-

Access to Proxy HTTP Server

—If local users have access to WAN proxy servers, they may be able to circumvent the router's content filters and access Internet sites blocked by the router. Denying Proxy blocks access to any WAN proxy servers.

Configuring IP Based ACL

The Firewall > IP Based ACL window displays a summary of the configured

IP-based access control list. The access list restricts 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 are read according to their priority.

If there is a match for a packet, the action is taken and the following lower priority rules are not checked against this packet.

NOTE

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 allows all traffic coming in from LAN port to pass the router. The second rule allows 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 is enabled if the Enable button is checked and if the date and time are matched. If any of the conditions are not met, the rule is not used to check against packets.

Configuring Single Port Forwarding

The Firewall > Single Port Forwarding window displays the specific port and other settings associated with each public service that uses just a single port.

Single Port Forwarding is one of the NAPT features and allows users of 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 forwards those requests to the appropriate servers on your LAN.

To configure single port forwarding for the router, follow these steps:

STEP 1

STEP 2

Click Firewall > Single Port Forwarding.

Configure single port forwarding settings for the router:

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.

STEP 3

Internal Port

—Port number used by the router when forwarding Internet traffic to the personal computer 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 uses 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 personal computer running the specific server application.

Enabled

—Select Enabled to enable port forwarding for the relevant server application.

Click Save.

Configuring Port Range Forwarding

The Firewall > Port Range Forwarding window displays the settings associated with public services accessed on your network that use single or multiple port numbers, such as web servers, FTP servers, e-mail servers, or other specialized

Internet applications that use one or multiple port numbers (for example, video conferencing). Port Range Forwarding is one of the NAPT (Network Address Port

Translation) features.

The Port Range Forwarding window allows you to configure access to these public services on your network. The port numbers being used does 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 forwards those requests to the appropriate servers on your LAN.

To set up IPSec for the router, follow these steps:

STEP 1

STEP 2

Click VPN > IPSec Setup.

Configure the security parameters for VPN IPSec:

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 is 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 768bit.

MD5— A one way hashing algorithm that produces a 128-bit digest.

SHA1— A one way hashing algorithm that produces a 160-bit digest.

Perfect Forward Secrecy

— If PFS is enabled, IKE Phase 2 negotiation generates a new key material for IP traffic encryption and authentication.

Note: that both sides must have this selected.

Preshared Key

— This field specifies a key used to authenticate IP traffic.

Both character and hexadecimal value are acceptable in this field. Note: that both sides must use the same Authentication Key.

Inbound SPI/Outbound SPI

—The SPI (Security Parameter Index) is carried in the ESP header. This enables the receiver to select the SA, under which a packet should be processed. The SPI is a 32-bit value. Both decimal and hexadecimal values are acceptable. for example, “987654321” or

“0x3ade68b1”. Each tunnel must have unique an Inbound SPI and Outbound

SPI. No two tunnels share the same SPI. Notice that Inbound SPI must match the other router's Outbound SPI, and vice versa

STEP 3

Viewing Connection Status

The Status section of the VPN > IPSec VPN window shows the connection status for the selected tunnel. The state is either connected or disconnected.

Configuring Virtual LANs (VLANs)

The L2 Switch > VLAN window displays the settings for creating and adding a

VLAN to the router.

VLANs are logical subgroups of a 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 network traffic to flow more efficiently within subgroups.

VLANs managed through software reduce the amount of time in which network changes are implemented.

VLANs are software based and not defined by physical attributes. They have no minimum number of ports and can be created per unit, per device, per stack, or any other logical connection combination.

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.

The WRVS4400N router supports up to 4 VLANs, including the default VLAN.

—If enabled, checks the VLAN ID on the incoming packet.

If the port is a member of this VLAN, accepts the frame. Otherwise, drops it.

If not enabled, all frames are accepted.

PVID

—The VLAN ID of the default (untagged) VLAN.

Configure VLAN settings for the router.

VLAN

— Select a VLAN ID to be configured.

VLAN Description

Display only. VLAN description to help you identify this VLAN

Tagged

— Egress frames from this port are tagged for this VLAN.

Untagged

—Egress frames from this port are untagged for this VLAN.

Excluded

—The port does not participate in this VLAN at all.

For the Access port mode, the available options are either untagged or excluded.

You can set a wireless port to one of these two modes for each VLAN. Only one of the VLAN IDs can be selected (untagged).

For the Trunk port mode, the options are tagged or excluded for all VLAN IDs except VLAN 1. VLAN 1 must be untagged.

For the General port mode, the options are tagged or untagged for PVID; tagged or excluded for all other VLAN IDs.

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:

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 VPN > VPN Pass Through. 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

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. Check the Cisco website at www.cisco.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.

I can’t get an 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:

When you have completed the configuration, click Save Settings.

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:

Frequently Asked Questions

A

Frequently Asked Questions

Q.

What is the maximum number of IP addresses that the router will support?

The router will support up to 253 IP addresses.

Q.

Is IPSec Passthrough supported by the router?

Yes, enable or disable IPSec Passthrough on the VPN > VPN Pass Through window.

Q.

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.

Q.

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.

Q.

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.

Q.

Does the router support any operating system other than Windows 98,

Millennium, 2000, or XP?

Yes, but Cisco does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems.

Q.

Does the router support ICQ send file?

Yes, with the following fix: click ICQ menu => preference => connections tab=>, and check I am behind a firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file to a user behind the router.

Q.

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.

Q.

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.

Q.

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.

Q.

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 window. What do I need to do?

Force your Ethernet adapter to 10 Mbps 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 Panel in your Ethernet adapter’s Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at www.cisco.com

Navigator is set to Direct connection to the Internet.

Q.

What is DMZ Hosting?

Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the

Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you want to use DMZ

Hosting.

Q.
