People,

I am trying to get to grips with simple source routing in the advance routing how-to.

I have a Linux box with two network cards

Eth0 192.192.192.3

Eth1 10.10.10.1

With IP Forwarding switched on any machine on either network can ping any other machine.

I can disable a user by adding a new route.

What I want to do really is enable a machine to pass though the gateway. Do I need IP Forwarding on for this and if not what routes should I put in place.

I guess I have missed something really simple here but I cant see it.

Thanks

Paul
