I have scoured the net, gotten a few pointers from several people and looked at several books and still have not come up with a satisfactory solution. I know someone has done it! Can some one point me to a reference for how to route two wan nics and two internal nics on the same box. I have tried using ip add to setup two separate lookup tables and route tables but to know avail. Any help greatly appreciated! This is what I have 66.92.114.46 209.141.2.194 | | xxxxxxxxxxxxxxxx Nated RedHat 7.3 will run ShoreWall xxxxxxxxxxxxxxxx 192.168.119.101 192.168.120.101 | | each network will have servers running here 192.168.119.100 192.168.120.100 xxxxxxxxxxxxxxxxx Nated failover box xxxxxxxxxxxxxxxxx 192.168.121.101 internal mail server ip ru 0: from all lookup local 32766: from all lookup main 32767: from all lookup 253 ip ro 66.92.114.32/28 dev eth0 scope link 209.141.2.192/27 dev eth1 scope link 192.168.119.0/24 dev eth2 scope link 192.168.120.0/24 dev eth3 scope link 127.0.0.0/8 dev lo scope link default via 66.92.114.33 dev eth0
