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. U

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 14

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” on page 16

•

“The Use of IP Addresses” on page 17

•

“The Intrusion Prevention System (IPS)” on page 19

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.




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.




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 the Basic Setup section in Chapter 5, “Setting Up and

Configuring the WRVS4400N Wireless-N Router.”

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.




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)

3

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

•

Why do I need a VPN?, page 21

•

What is a VPN?, page 23

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.



Why do I need a VPN?

3

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” on page 22

•

“Data Sniffing” on page 22

•

“Man in the Middle Attacks” on page 22

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.



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.

POWER LED —Lights up green to indicate the router is powered on. The LED flashes when the router is running a diagnostic test.

DIAG LED —If this light is off, the system is ready. The Diag LED blinks red during firmware upgrades.

IPS LED —The IPS LED lights up when the Intrusion Prevention System (IPS) function is enabled. If the LED is off, then IPS functions are disabled. The IPS

LED flashes green when an external attack is detected. It flashes red when an internal attack is detected.

Wireless LED —The WIRELESS LED lights up when the wireless module is enabled. The LED is off when the wireless module is disabled. The WIRELESS

LED flashes green when the data is transmitting or receiving on the wireless module.

Ethernet Port LEDs 1-4 —For each LAN port, there are three LEDs. If a port

LED is continuously lit green, the router is connected to a device at the speed indicated through the corresponding port (1, 2, 3, or 4). The LED flashes green when a router is actively sending or receiving data on that port.

INTERNET LED —The Internet LED lights up green to indicate the line speed of the device attached to the Internet port. If the router is connected to a cable or

DSL modem, typically the 100 LED will be the only LED lit up, indicating

100 Mbps. Flashing indicates activity.



Back Panel

The Ethernet ports, Internet port, Reset button, and Power port are on the back panel of the router.

RESET Button —The Reset button can be used in two ways:

• If the router is having problems connecting to the Internet, press the Reset button for just a second with a paper clip or a pencil tip.

This is similar to pressing the reset button on your personal computer to reboot it.

• If you are experiencing extreme problems with the router and have tried all other troubleshooting measures, press and hold in the Reset button for 10 seconds. This restores the factory defaults and clears all of the router settings, such as port forwarding or a new password.

Configuring the Router’s Advanced Settings

The Setup > Advanced Routing window allows you to configure the router’s

Operating Mode and settings for Dynamic Routing, Static Routing, and Inter-VLAN routing.

To configure your router’s advanced settings, follow these steps:

STEP 1 Click Setup > Advanced Routing

STEP 2 Fill in the settings for advanced routing configuration:




5

• To select the 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 addresses—in Intranet Router mode, the NAT mechanism is disabled.

STEP 3 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.




5 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.

STEP 4 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.




STEP 5 View the Routing Table if necessary to verify routing.

To view the routing table established either through dynamic or static routing methods, click the Show Routing Table button.

5

STEP 6 Enable Inter-VLAN Routing if needed.

Select Enable to allow packets to be routed between VLANs that are in different subnets. The default is Enable.





5

Changing the Router’s Time Settings

The Setup > Time window allows you to either define your router’s time manually or automatically through the Time Server. The default is Automatically.

To define your router’s time, follow these steps:

STEP 1 Click Setup > Time.

STEP 2 Specify how to set the local time: a. Manually

• Set the local time Manually—If you wish to enter the time and date manually, select the Date from the drop-down fields and enter the hour, minutes, and seconds in the Time field using 24 hour format (example

10:00pm would be entered 22:0:0).

b. Automatically




5

• Set the local time using Network Time Protocol (NTP) Automatically—If you wish to use a Network Time Protocol server to set the time and date, select this option, then complete the following fields.

Time Zone—Select the time zone for your location and your setting synchronizes over the Internet with public NTP (Network Time Protocol)

Servers.

Auto Daylight Saving—If your location observes daylight savings time, select the Enable option.

User Defined NTP Server—To use your own NTP server, select the

Enabled option. The default is Disabled.

NTP Server IP Address—Enter the IP address of your own NTP server.





5

Selecting IPv4 Mode or Dual Stack IPv4 And IPv6 Mode

The Setup > IP Mode window allows you to choose IP Mode settings for the router.

To configure IP Mode settings for the router, follow these steps:

STEP 1 Click Setup > IP Mode.

STEP 2 Configure the IP Mode settings:

• IPv4 Only—Select this option to use IPv4 on the Internet and local network.

• Dual-Stack IP—Select this option to use IPv4 on the Internet and IPv4 and

IPv6 on the local network.




5

• 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.

Permit following sites—Allow only a limited set of 6to4 gateways to establish tunnel with the router. Up to 20 sites can be configured and they can send traffic simultaneously.




5

.

Block following sites—Prevent a limited set of 6to4 gateways from establishing tunnels with the router. Up to 20 sites can be configured.




5

• Static 6to4 DNS entry—Allow users to configure static DNS entry to map hostname to IPv6 address. This provides a convenient way for users to access remote IPv6 hosts.

Click this button and a window appears to let you select a MAC address from the table. The selected MAC address are entered into the Connection Control List.

MAC 01-20—The MAC addresses of the wireless client devices you want to control (i.e. the Connection Control List).


Configuring Advanced Wireless Settings

The Wireless > Advanced Settings window displays the advanced settings for the router. The router adopts several new parameters to adjust the channel bandwidth and guard intervals to improve the data rate dynamically.

It is recommended that you let your router automatically adjust the parameters for maximum data throughput.




5

To configure advanced wireless settings for the router, follow these steps:

STEP 1 Click Wireless > Advanced Settings.

STEP 2 Configure the advanced wireless settings as needed by changing the following advanced parameters (some only for Wireless-N) for this router.

Wireless-N data rates are classified into 16 MCS numbers (0-15). MCS stands for

Modulation and Coding Scheme. For the same MCS number, the data rate changes according to the Channel Bandwidth and Guard Interval settings.

• Channel Bandwidth—Select the channel bandwidth manually for Wireless-

N connections. When it is set to 20MHz, only the 20MHz channel is used.

When it is set to 40MHz, Wireless-N connections use 40MHz channel but

Wireless-B and Wireless-G connections still use 20MHz channel. The default is Auto.

• Guard Interval—Select the guard interval manually for Wireless-N connections. The two options are Short (400ns) and Long (800ns). The default is Auto.




5

• CTS Protection Mode—CTS (Clear-To-Send) Protection Mode function boosts the router’s ability to catch all wireless transmissions, but severely decrease performance. Keep the default setting, Auto, so the router can use this feature as needed, when the Wireless-N/G products are not able to transmit to the router in an environment with heavy 802.11b traffic. Select

Disabled if you want to permanently disable this feature.

• Beacon Interval— 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.

• RTS Threshold— Determines how large a packet can be before the router coordinates transmission and reception to ensure efficient communication.

This value should remain at its default setting of 2346. If you encounter inconsistent data flow, only minor modifications are recommended.





5

Configuring VLAN & QoS Settings

The Wireless > VLAN & QoS window displays the QoS and VLAN settings for the router’s Access Point. The QoS (Quality of Service) feature allows you specify priorities for different traffic. Lower priority traffic slows down to allow greater throughput or less delay for high priority traffic.

The 802.1Q VLAN feature allows traffic from different sources to be segmented.

Combined with the multiple SSID feature, this provides a powerful tool to control access to your LAN.

To configure the VLAN and QoS settings for the router, follow these steps:

STEP 1 Click Wireless > VLAN & QoS

STEP 2 Configure the VLAN and QoS settings for the router:

• VLAN

Enable/Disable VLAN—Enable this feature only if the hubs/switches on your LAN support the VLAN standard.

IP based Access List, restricting LAN users on Internet (WAN port) access, and

NAPT (Network Address Port Translation) to limited services to specific ports.

Settings only work when NAT is enabled.

NOTE For WAN traffic, NAPT settings are applied first, then the SPI Firewall settings, followed by IP based Access List (which requires more CPU power).




5

Configuring Basic Settings

The Firewall > Basic Settings window displays the firewall-specific settings of the router.

To configure basic firewall settings for the router, follow these steps:

STEP 1 Click Firewall > Basic Settings.

STEP 2 Configure the basic firewall settings:

• Firewall—Enable this feature to perform deep packet inspection on all the traffic going through the router and drop the packets that do not follow the pre-defined protocol behavior. The default is Enable.

• DoS Protection—When enabled, the router prevents DoS (Denial of

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.




5

• 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.





5

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.




5

To configure the IP Based ACL for the router, follow these steps:

STEP 1 Click Firewall > IP Based ACL.

STEP 2 Configure the IP based ACL settings for the router:

• Priority—Defines the order on which rule is checked against first. The smaller number has higher priority. The default rules is always be checked last.

• Enable—Tells the router if the rule is active or not. You can have rules defined in the ACL Table but in an inactive state. The administrator can decide on when to enable specific ACL rules manually.

• Action—Defines how the rule is to affect the traffic. It can be either Allow or

Deny. If the rule is matched and the action is Allow, the packet is forwarded.

If the rule is matched and the action is Deny, the packet is dropped.

• Service—Select one of the pre-defined services in the drop-down menu or you can define new services by clicking Service Management. When you define your own service, it is listed on the top of the drop-down menu. You can also select ALL to allow or block all types of IP traffic.

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 Click Firewall > Single Port Forwarding.

STEP 2 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.




5

• 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.


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 configure port range forwarding for the router, follow these steps:

STEP 1 Click Firewall > Port Range Forwarding.

STEP 2 Configure port range forwarding settings for the router:

5


• Start—Enter the beginning of the port number range (external ports) used by the server or Internet application. For more information, check the software documentation of the Internet application.

• End—The end of the port range. Enter the end of the range of port numbers

(external ports) used by the server or Internet application. For more information, check the software documentation of the Internet application.

• 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 application.

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





5

Configuring Port Range Triggering

The Firewall > Port Range Triggering window displays the configurations of triggered range and forwarded range of ports that are used by applications that request ports to be opened on demand. Port Range Triggering is an NAPT

(Network Address Port Translation) feature.

Port Range Triggering is used for special applications that can request a port to be opened on demand. For this feature, the router watches outgoing packets for specific port numbers. This triggers the router to allow the incoming packets within the specified forwarding range and forward those packets to the triggering personal computer. One of the example applications is QuickTime. It would use port 1000 for outgoing packets and 2000 for incoming packets.

To configure port range triggering for the router, follow these steps:

STEP 1 Click Firewall > Port Range Triggering.

STEP 2 Configure port range triggering settings for the router:




5

STEP 1 Click VPN > IPSec Setup.

STEP 2 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.




5

• 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. Notice that both sides

(VPN endpoints) 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.

• 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

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.




5

To configure Virtual LANS for the router, follow these steps:

STEP 1 Click L2 Switch > Create VLAN.

General—All frames can be tagged or untagged coming in to the switch.

If untagged, the default PVID applies to the packet. Only the General mode users can choose the Acceptable Ingress Frame Type and PVID options.

NOTE The Acceptable Ingress Frame Type and PVID options cannot be supported on the Vitesse 7385 switch chipset

• Acceptable Ingress Frame Type

All Frames—All the incoming frames are acceptable.

Tagged Only—Only tagged incoming frames are acceptable.

• Ingress Filtering—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.

STEP 3 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 am not getting an IP address on the Internet with my Internet connection.

STEP 1 Refer to

“I want to test my Internet connection.” on page 188

above to verify that you have connectivity.

STEP 2 If you need to clone the MAC address of your Ethernet adapter onto the router, see the MAC Address Clone section of Chapter 5, “Setting Up and Configuring the

Router” for details.

STEP 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 5, “Setting

Up and Configuring the Router” for details on Internet Connection Type settings.

STEP 4 Make sure you use the right cable. Check to see if the Internet LED is solidly lit.



STEP 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.

STEP 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 System > Summary from the router’s web-based utility to see if you get an IP address.

I am not able to access the router’s web-based utility Setup window.

STEP 1

Refer to “I want to test my Internet connection.,” on page 188 to verify that your

computer is properly connected to the router.

STEP 2 Verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS.

STEP 3

Set a static IP address on your system; refer to “I need to set a static IP address on a PC.” on page 186

above.

STEP 4 Refer to

“I am a PPPoE user and I need to remove the proxy settings or the dial-up pop-up window.,” on page 194

.

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 router’s IP address through the Setup menu 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. Check the Cisco website at www.cisco.com


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.

STEP 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 Firewall > Single Port Forwarding.

STEP 2 Select the Service from the Application column.

STEP 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. Then check the Enable checkbox for the entry. Consider the examples below:

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:

STEP 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.

STEP 2 Disable the entries you have entered for forwarding.

STEP 3 Go to Setup > DMZ.

STEP 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.

STEP 5 Select Enable to enable DMZ Hosting.


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:

STEP 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 Firewall > Single Port Forwarding.

STEP 2 Select the Service from the Application column.



STEP 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. Then check the Enable checkbox for the entry. Consider the examples below:

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:

STEP 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 Administration >

Management.

STEP 2 Enter the old password in the Old Password field.

STEP 3 Enter a different password in the New Password field, and enter the new password in the Confirm New Password field to confirm the password.




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:

STEP 1 Click Start, Settings, and Control Panel. Double-click Internet Options.

STEP 2 Click the Connections tab.

STEP 3 Click LAN settings and remove anything that is checked.

STEP 4 Click OK to go back to the previous window.

STEP 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:

STEP 1 Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies.

STEP 2 Make sure you have Direct connection to the Internet selected on this window.

STEP 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.



I need to upgrade the firmware.

In order to upgrade the firmware with the latest features, you need to go to the

Cisco website and download the latest firmware. For the firmware download link, see Appendix G, “Where to Go From Here.” Follow these steps:

STEP 1 Go to the Cisco website and download the latest firmware. For the firmware download link, see Appendix G, “Where to Go From Here.” From the firmware download link, click Download Software. Select the router from the menu and choose the firmware from the options.

STEP 2 Extract the firmware file on your computer.

STEP 3 To upgrade the firmware, follow the steps in the Upgrade section found in

Chapter 5, “Setting Up and Configuring the Router.”

The firmware upgrade failed.

The upgrade could have failed for a number of reasons. Use the WRVS4400N

Firmware Upgrade Utility to upgrade the firmware. Follow these steps to upgrade the firmware:

STEP 1 Go to the Cisco website at www.cisco.com

and download WRVS4400N Firmware

Upgrade Utility v1.3, which will be listed with the firmware. Save the zip file to your computer.

STEP 2 Extract the file setup.exe from the zip file, then run setup.exe to install the utility on your computer.

STEP 3 Disconnect the network cables from all of the router’s LAN and WAN ports, except the network cable to the computer that has the firmware upgrade utility.

STEP 4 Run the utility by clicking Start, All Programs, Cisco Small Business, RVS4400N

Upgrade Utility, RVS4400N Upgrade Utility, or by double-clicking the icon on your desktop.

STEP 5 Follow the on-screen instructions to perform the upgrade.



My DSL service’s PPPoE is always disconnecting.

PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a period of inactivity, just like a normal phone dial-up connection to the Internet. There is a setup option to “keep alive” the connection.

This may not always work, so you may need to re-establish connection periodically.

STEP 1 To connect to the router, go to the web browser, and enter http://192.168.1.1 or the IP address of the router.

STEP 2 Enter the password, if asked (default password is admin).

STEP 3 On the Setup > WAN menu, select the option Keep Alive, and set the Redial

Period option at 20 (seconds).


If the connection is lost again, follow steps 1 and 2 to re-establish connection.

I can’t access my e-mail, web, or VPN, or I am getting corrupted data from the Internet.

The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500. For most DSL users, it is strongly recommended to use MTU 1492. If you are having difficulties, perform the following steps:


STEP 2 Enter the password, if asked (the default password is admin).

STEP 3 Go to the Setup > WAN menu.

STEP 4 Look for the MTU option, and select Manual. In the Size field, enter 1492.

STEP 5 Click Save Settings to continue.

If your difficulties continue, change the Size to different values. Try this list of values, one value at a time, in this order, until your problem is solved: 1462, 1400,

1362, and 1300.



I need to use port triggering.

Port triggering looks at the outgoing port services used and will trigger the router to open a specific port, depending on which port an Internet application uses.

Follow these steps:


STEP 2 Enter the password, if asked (the default password is admin).

STEP 3 Click Firewall > Port Range Triggering.

STEP 4 Enter any name you want to use for the Application Name.

STEP 5 Enter the Start and End Ports of the Triggered Range. Check with your Internet application provider for more information on which outgoing port services it is using.

STEP 6 Enter the Start and End Ports of the Forwarded Range. Check with your Internet application provider for more information on which incoming port services are required by the Internet application.

STEP 7 Check the Enabled checkbox for the entry.




When I enter a URL or IP address, I get a time-out error or am prompted to retry.

• Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address, Subnet Mask, Default Gateway, and DNS).

Restart the computer that is having a problem.

• If the PCs are configured correctly, but still not working, check the router.

Ensure that it is connected and powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.)

• If the router is configured correctly, check your Internet connection (DSL/ cable modem, etc.) to see if it is working correctly. You can remove the router to verify a direct connection.

• Manually configure the TCP/IP with a DNS address provided by your ISP.

• Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the

Connection tab. Make sure that Internet Explorer is set to Never dial a

connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct connection

to the Internet.

I’m trying to access the router’s web-based utility but I do not see the login window. Instead, I see a window saying, “404 Forbidden.”

If you are using Windows Explorer, perform the following steps until you see the web-based utility’s login window (Netscape Navigator will require similar steps):

STEP 1 Click File. Make sure Work Offline is NOT checked.

STEP 2 Press CTRL + F5. This is a hard refresh, which will force Windows Explorer to load new web pages, not cached ones.

STEP 3 Click Tools. Click Internet Options. Click the Security tab. Click the Default level button. Make sure the security level is Medium or lower. Then click the OK button.

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.


Troubleshooting


A

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



Troubleshooting


A

Q. If all else fails in the installation, what can I do?

Reset the router by holding down the Reset button for ten seconds. Reset your cable or DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is readily available on the Cisco website at www.cisco.com

.

Q. How can I be notified of new router firmware upgrades?

All Cisco firmware upgrades are posted on the Cisco website at www.cisco.com

, where they can be downloaded for free. The router’s firmware can be upgraded using the web-based utility. If the router’s Internet connection is working well, there is no need to download a newer firmware version, unless that version contains new features that you would like to use. Downloading a more current version of router firmware will not enhance the quality or speed of your Internet connection, and may disrupt your current connection stability.

Q. Will the router function in a Macintosh environment?

Yes, but the router’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or higher for Macintosh.

Q. I am not able to get the web configuration window for the router. What can I do?

You may have to remove the proxy settings on your Internet browser, e.g.,

Netscape Navigator or Internet Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation, and make sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is set to connect directly and that any dial-up is disabled. For

Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape

Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape

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. If DMZ Hosting is used, does the exposed user share the public IP with the router?

No.


Troubleshooting


A

Q. Does the router pass PPTP packets or actively route PPTP sessions?

The router allows PPTP packets to pass through.

Q. Is the router cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the router.

Q. How many ports can be simultaneously forwarded?

Theoretically, the router can establish 2,048 sessions at the same time, but you can only forward 30 ranges of ports.

Q. 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.

Q. Which modems are compatible with the router?

The router is compatible with virtually any cable or DSL modem that supports

Ethernet.

Q. How can I check whether I have static or DHCP IP addresses?

Ask your ISP to find out.

Q. How do I get mIRC to work with the router?

From the Firewall > SIngle Port Forwarding menu, set port forwarding to 113 for the PC on which you are using mIRC.
