Routing Table
The routing table lets the ProxyServer know about other networks that are part of your
LAN. If there are no routers on your network you can skip this section.
For each router on your network:
1) Enter the IP address and Subnet Mask of the Network you wish to route to. In our
example below, our second network has IP addresses of “192.168.2.x” . We have
thus entered the IP address “192.168.2.0” and a netmask of 255.255.255.0
The last digit “ 0 ” on the subnet mask defines the subnet of your network.
2) Enter the Gateway (IP address) of your network’s router. Usually a router has two IP
addresses; one for each side of the two networks that it routes between. You should
enter the router’s IP address that is on the same side as your ProxyServer. In our
example the IP address of our router is “213.0.0.10”
3) Set the Interface to Local Network
4) Click Insert.
5) Click OK.
What is the purpose of the routing table?
The routing table is important if you have routers on your LAN. The Internet is basically
one giant network that uses IP addresses to locate it’s different sites and works the same
way as IP addressing on your LAN. Say your LAN has two networks and someone on
Network 1 wants to send an E-mail locally to Network 2. How does that E-mail know to
stay in the LAN and not go out through your gateway (i.e., your ProxyServer)? The
reason is because your router sees the E-mail that has an IP address corresponding to
your other network and shouldn’t go out through the ProxyServer.
