I have a linux box setup with an openvpn client and a secondary ip address associated with its NIC. I have it configured to route traffic from this ip to the vpn. This ip address is 192.168.1.7
I have my router setup with shibby's tomato. I have it setup with a second wireless interface (which is open). It uses a secondary LAN segment, 192.168.2.0/24.
Under Advanced/LAN Access, I have an entry allowing 192.168.2.0/24 to connect to 192.168.1.7. I may possibly add entries in the future allowing other access between the segments.
Now, I want to route all inet traffic from that LAN segment to 192.168.1.7. I know this is probably done with iptables command in the startup script, but I want to insure that none of this segment's traffic will go out directly through my ISP. Of secondary concern is redirecting this segment's DNS requests.
