[arch-general] iptables not working well?

[Damjan Georgievski]

Your config looks ok, but to double check, paste the output of:
iptables -L -nv
iptables -t nat -L -nv
to see the exact situation.

What's the error you are getting. Are you ping-ing by name or by an IP address.
Have you tried ping-ing with different packet sizes?

on your gateway machine run tcpdump on both the LAN and ppp0 interface
and see if the packets go through.
