Postrouting is the correct one. After everything is routed it is MASQ before leaving the interface.
That makes sense, but I am stuck at making the transition, should I simply pull the port specifications from my third line in the FORWARD chain to the first line in the POSTROUTING chain?
iptables -A POSTROUTING -t nat -o $WAN -p tcp -m multiport --dports 80,443 -j MASQUERADE iptables -A FORWARD -i $WAN -o $LAN -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i $LAN -o $WAN -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
Does that look groovy?
