I'll look at this, I made the existing nat code in 1.2 iirc.

I just tested this with multi wan on 2.0 from a 18-11-2009 snapshot.

I have rules for both WAN connections and all known internal subnets. Both the static routes, and the directly connected networks.

tonatsubnets = "{ 192.168.10.0/24 192.168.11.0/24 192.168.2.0/24 }"
no nat on $WAN to port tftp
nat on $WAN from $tonatsubnets port 500 to any port 500 -> 213.73.159.94/32 port 500
nat on $WAN from $tonatsubnets port 5060 to any port 5060 -> 213.73.159.94/32 port 5060
nat on $WAN from $tonatsubnets to any -> 213.73.159.94/32 port 1024:65535
no nat on $WLANC to port tftp
nat on $WLANC from $tonatsubnets port 500 to any port 500 -> 192.168.1.117/32 port 500
nat on $WLANC from $tonatsubnets port 5060 to any port 5060 -> 192.168.1.117/32 port 5060
nat on $WLANC from $tonatsubnets to any -> 192.168.1.117/32 port 1024:65535

Patches commited.
