2.4 doesn't support this, unfortunately. Or, at least, in the hours I've
spent searching for info, I found absolutely nothing about it (besides
confirmation that it's not supported). You'll need to enable port
forwarding manually.
This is how I do it for Starcraft (and other battle.net games). The router
is 192.168.1.1. I use 192.168.1.2 as my Windows box which hosts games. The
for loop adds forwarding for 192.168.3-8. eth0 is the external interface
(connected to the internet).
FWN="/sbin/iptables -t nat"
IFACE="eth0"
EXTIP=$(ifconfig $IFACE | awk '{print $2}' | grep addr | cut -b 6-)
for i in 3 4 5 6 7 8
do
$FWN -A PREROUTING -p udp -d $EXTIP --dport 6300$i \
-j DNAT --to-destination 192.168.1.$i:6112
$FWN -A POSTROUTING -p udp -s 192.168.1.$i \
--sport 6112 -j SNAT --to-source $EXTIP:6300$i
done
$FWN -A PREROUTING -p udp -d $EXTIP --dport 6112 \
-j DNAT --to 192.168.1.2:6112
$FWN -A POSTROUTING -p udp -d 192.168.1.2 --dport 6112 \
-s 192.168.1.0/24 -j SNAT --to 192.168.1.1
