think lan1 lan2 wan1 wan2 the firewall box, must have NO defaul route ip rule add from lan1 lookup table 5 ip rule add from lan2 lookup table 6 ip route add default via wan1 table 5 ip route add default via wan1 table 6 thats it. ----- Original Message ----- From: "Ryan Johnson" <rjohnson@xxxxxxxxxxxx> To: <netfilter@xxxxxxxxxxxxxxxxxxx> Sent: Monday, January 26, 2004 2:49 PM Subject: Firewall four nics, two separate routes Hi all, I have a firewall with four nics, two external nics with two public ips and two internal nics with private ips (two different networks). What I would like to do is force all traffic from each internal network to its corresponding external nic. I believe the only solution to this is to use iproute2, but I have had to luck. So traffic from internal net1 will be routed out external nic1, then the other side, internal net2 will be routed out the external nic2. Internal net1 traffic should never go out external nic2 and internal net2 traffic should never go out external nic1. Thank you in advance, Ryan Ryan Johnson Security Architect ESP Group
