I have 3 network cards on my system and I want to be able to forward

eth1 to LAN2 eth2. I added a rule in iptables to stop forwarding from
the IP address on eth1 to eth2.
But I started looking at ethereal packets to determine how I was
getting from LAN1 to LAN2 and the ethereal output indicated that I was
going through eth0.
I'm sure that I can probably fiddle around with iptables until I can
stop this, but is there a way configure routes more explicitly to
prevent this action.
Are you running NAT on this setup? Do you have the default policy set
to Drop? Are you specifiying both interfaces when you are forwarding?
Please post the result from: iptables -v -L FORWARD
.
