Hi

If I have a web server in my DMZ, then I have a PREROUTING rule to
redirect incoming traffic to the server, like :
$IPTABLES -t nat -A PREROUTING -i $IFACE_INET -p tcp --dport 80 -d
$IP_INET_WEB1 -j DNAT --to $IP_INT_WEB1

I also have the FORWARDing rules ...

Do I need a POSTROUTING rule in the nat table for return/reply traffic,
or is that automagically handled by nat?

Obviously I have the FORWARD rule to forward the replies from
$IP_INT_WEB1 back to the source.

Ray
