how to route thru virtual interfaces?


I have three linux boxes and a few Windows boxes.When i enable ip forwarding on the linux box (ip address 192.168.13.12), other machines can connect thru it and it forwards their requests to the router.They can then access internet. However, when i setup a virtual ip address on the same Network card of the linux machine(ifconfig eth0:0 192.168.0.1 netmask 255.255.255.0) and i change the gateway of the other clients to that of the virtual ip address(192.168.0.1), these clients cannot access internet. Is there a way i can forward requests from the virtual address(192.168.0.1) to the real address(192.168.13.12) such that the clients can access internet thru the virtual address(192.168.0.1)? please help.

From what i can see you other machines are on the wrong subnet.

You'll need to give all the other machines a 192.168.0 address as well for them to be able to see the 192.168.0.1 computer.

For what reason are you adding this virtual address?

Done that already.

I did that to the clients..ie gave them configurations of 192.168.0. network and they can even ping the virtual address of 192.168.0.1 but they cannot access internet if i configure them to use the virtual address as the gateway. Why can't they connect?

Then you'll need to setup some static routes for ip forwarding on the server to route incoming internet requests to the internet gateway.
