When I typed the email below, I mistyped the rt200ne settings. The following are the settings for rt200ne: rt200ne=192.168.40.1 rt200ne=192.168.40.3 -----Original Message----- From: netfilter-owner@xxxxxxxxxxxxxxx [mailto:netfilter-owner@xxxxxxxxxxxxxxx] On Behalf Of jwexler@xxxxxxxxxxxx Sent: Wednesday, July 28, 2010 7:47 PM To: 'Jan Engelhardt'; netfilter@xxxxxxxxxxxxxxx Subject: RE: Bidirectionally Route all traffic to an ip to another ip I nearly got it working but still no dice. iptables -t nat -A OUTPUT -p all -d 192.168.40.3 -j DNAT --to-destination 192.168.40.1 (Note: -A PREROUTING did not work at all but -A OUTPUT got me closer) iptables -t nat -A POSTROUTING -p all -j MASQUERADE iptables -t nat -n -L Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- 0.0.0.0/0 0.0.0.0/0 Chain OUTPUT (policy ACCEPT) target prot opt source destination DNAT all -- 0.0.0.0/0 192.168.40.3 to:192.168.40.1 "ping 192.168.40.3 -I eth1" and "ping 192.168.40.3" both work fine.

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!!
