Hi,
I have a question related to a NAT connection behavior:

|CLIENT|<----->[ROUTER/IPTABLES/NAT]<---->|SERVER|

Why is it that if I ping SERVER from CLIENT, I see answers comming
from SERVER internal IP instead of ROUTER external IP.

NAT rule on ROUTER is:

iptables -t nat -A POSTROUTING -s <IP SERVER> -o <external eth of
ROUTER> -j SNAT --to-source <external IP of ROUTER>

I know that it is awful too basic question for you guys, but if
someone could explain that I'll be much appreciative.
