Message-ID: <016701c2e28a$239fbab0$1f0016ac@daviddesktop> (raw)

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?

Thanks,
David Ruggles
