Wireless-N Router

The Wireless-N router works right out of the box with the default settings.

However, to change these settings, you can use the router’s web-based configuration utility.

You can access the web-based configuration utility via a web browser (such as

Microsoft Internet Explorer or Mozilla Firefox) from a computer connected to the same network the router is connected to.

Setting Up and Configuring the WRVS4400N Wireless-N Router

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.

NOTE Wirelessly connecting your personal computer to the router for initial configuration is not recommended because you might lose the connection while making wireless configuration changes.

To access the router’s web-based utility, follow these steps:

STEP 1 Launch a web browser, such as Internet Explorer or Mozilla Firefox, and enter the router’s default IP address, 192.168.1.1, in the Address field. Then, press Enter.

The Authentication Required dialog box appears.

STEP 2 Enter admin in the User Name field, and enter your password (default password is

admin) in the Password field. Then, click OK.

The Summary window appears.

• 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.

Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN Administration Guide 67

Setting Up and Configuring the WRVS4400N Wireless-N Router

Setting Up Your Wireless-N Router

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.

• 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.

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 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.

Setting Up and Configuring the WRVS4400N Wireless-N Router

Configuring Firewall Settings

• 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.

STEP 3 Click Save.

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 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.

(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.
