Did you actually do what I suggested; Google search for 'linux router'?

There are literally hundreds of great pages with the answer to your question. Here are four:

not with other OS

any idea??

good thx every body....

Hmm..What exactly did you mean?
did you mean:
If so just write a minor script which checks ifconfig's output with some minute cooldown and sets the gateway according to the info it got

not exactly..!

1- i want to if any Pc from Net1 connected to linux router through iface1 uses Gateway associated with iface1.

2- if any Pc from Net2 connected to linux router through iface2 uses Gateway associated with iface2.

there is no answer ....

Your picture makes no sense to me. Where are packets routed through your linux router expected to go? All I see is a computer with two NICs, each connected to a port on the same switch. The switch effectively short-circuits traffic through the system of gateways and router. And what are the "GATEWAY"s, anyway? Having said all of this, there is nothing about the linux router that makes it fundamentally different from a standard iptables based router/firewall. Fedora comes with all the necessary components to make it into a router. You need to configure it according to your own requirements. From the look of your drawing, that should be extraordinarily simple. Pass everything from eth0 on to eth1, and vice versa. If you are looking for a detailed description of every step you need to take to get there, then it is too general to answer in that level of detail. As I said before, this stuff is well documented out there already. Give it a try, and come back here when you run into more specific problems.
