How do I route inside my network?
I have a network and I divided in two by changing the subnet mask and using a linux box with 2 interface cards. One of these is connected to the hub where the gateway is connected. The other one is connected to my other computers, but I turned on the forwarding ( echo 1 > /proc/net/sys/ipv4/ip_forwarding ) and set up my interface cards, set the routing table correctly with ip, and in the side of my computers set the default gateway to the interface that is connected to the hub of my second network.
Forwarding does't happen. I'm doing this because I want to filter the traffic between the internet and my other computers, because they have real internet addresses. Please help!
