I'm trying to learn netfilter so I've got a very simple setup. I've got a Linux box with three interfaces. (I'm not using eth0 currently) I've got two networks (eth2: 172.22.0.0 & eth1: 10.0.0.0) I entered the following on the Linux box: iptables -t nat -A POSTROUTING -o eth1 -j SNAT --to 10.9.0.254 (eth1's IP address) I've got a machine on each network: machine A is on 172.22.0.0 and machine B is on 10.0.0.0 I'm trying to ping from A to B. I can ping all the interfaces on the router but I can't ping B I would expect to see the POSTROUTING chain counter increment for each ping packet, but it doesn't. (It will increment if I ping from the Linux box to B) Any suggestions?
