Filters
Filters block specific internal users from accessing the Internet. You can set up a filter through an IP address or a network Port number.
To Modify Filter Settings
Enter the IP addresses that you want to filter into the IP address fields. The users who have these IP addresses will not be able to access the Internet.
You can also filter users by entering their network port number. Enter the port numbers you want to filter into the port numbers fields. Users who are connected to the Router will no longer be able to access any port number listed there.
To block external parties from making data requests of your LAN, enable the "Block WAN Request" selection.

Forwarding
Port forwarding sets up public services on your network. When users from the Internet make certain requests of your network, the router will forward those requests to the appropriate computer. The router's DHCP function must be disabled to use Forwarding. Forwarding is generally used to set up a webserver, ftp server, or e-mail server on your network.
To add a server using Forwarding:
Enter the port number used by the server. On the same line, enter the IP Address of the server that you want the Internet users to be able to access.
Configure as many entries as you would like until all of the link entries are filled.

Dynamic Routing
With Dynamic Routing you can automatically adjust to physical changes in the network's layout. The router, using the RIP protocol, determines the network packets� route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network.
To set up Dynamic Routing:
Choose the correct working mode. Gateway Mode should be used if your Linksys router is hosting your network's connection to the Internet. Router Mode should be selected if the router exists on a network with other routers.
Choose the protocol by which you transmit data on the network.
Choose the protocol by which the Router receives network data.

Static Routing
If there are multiple routers on your network, it is necessary to configure the unit's static routing functions. The static routing function determines your network�s data paths. Use static routing to allow different IP domain users to access the Internet through your Cable/DSL Router. Click on the Show Routing Table button to view the current routing table.
To create a static route entry:
Select a Static Route Entry from the drop down list. The device supports up to 20 static route entries.
Enter the following data for the static route:
Destination LAN IP : Enter the network address of the remote LAN segment. For a standard Class C IP domain, the network address is the first 3 fields of the Destination LAN IP, while the last field should be 0.
Network Mask : Enter the Subnet Mask used on the destination LAN IP domain. For Class C IP domain, the Subnet Mask is 255.255.255.0.
Gateway IP : If the Linksys router is the main IP router to connect your network to the Internet, then your Gateway IP is the same IP Address as the Linksys router. If you have another router handling your network's Internet connection, enter the IP Address of your main Internet router here instead.

DMZ Host
The DMZ Host setting allows one local user to be exposed to the Internet to use a special-purpose service such as Internet gaming or Video-conferencing. To expose one computer, enter the computer�s IP address and click the Apply button. Inactivate DMZ by entering a zero (0).
For more details please refer to the documentation that came with your router and check the Linksys website and other resources for additional information.
