The last time I did that I did it on Centos 5. Here are my notes from back then. First, add two lines to /etc/iproute2/rt_tables, so it looks like this: # # reserved values # 255 local 254 main 253 default 0 unspec # # local # #1 inr.ruhep 50 access1 60 access2 Then add the following routes: ip route add 1.2.3.0/24 dev eth1 table access1 ip route add default via 1.2.3.1 dev eth1 table access1 ip rule add from 1.2.3.178/32 lookup access1 ip route add 1.2.3.0/24 dev eth2 table access2 ip route add default via 1.2.3.1 dev eth2 table access2 ip rule add from 1.2.3.180/32 lookup access2 Of course, in this example 1.2.3.178 is the IP address of the first nic and 1.2.3.180 is the address of the second nic. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
