Thanks. It still did not work. Should I only be doing a ip route add 192.168.50.1/32 via 192.168.40.1 statement or should I also be adding iptables commands? I am having trouble getting the ip route add 192.168.50.1/32 to use dev eth1 instead of eth0. When I do: ip route add dev eth5 192.168.50.1/32 via 192.168.40.1 I get an error: RTNETLINK answers: No such process Should I also be doing some kind of ip addr add dev eth5? And/or add src 192.168.50.1/32 to the ip route add command somehow? I have tried many combinations but still have not gotten it to work yet. Thanks!!
