[PLUG] Port redirection on a firewall ?

[Richard Langis]

For mail:

  $iptables -A FORWARD -i $if_ext -p tcp -d $host --dport 25 -j ACCEPT

http:

  $iptables -A FORWARD -i $if_ext -p tcp -d $host --dport 80 -j ACCEPT

Where $iptables is where `which iptables` shows up, $if_ext is your 
external (firewalled) interface, and $host is the machine you are 
routing to.
