I am trying to get my two WAN ethernet connections into one box to work.
Eth2 is cable, eth1 is T1 and eth0 is office LAN. Eth2 works just fine. connections on eth1 dont seem to go anywhere.
I thought it was the routing based on route -n info.
I am also using iptable to preroute and postroute.
What exactly does not work? Connecting to what destination IP? Your default route is pointing out eth2. So any traffic to a non-directly connected network will go out eth2. (without some additional static routes) What are you trying to accomplish?
