This is the script I use now:

#config IPMASQ
echo "1" > /proc/sys/net/ipv4/ip_forward
/sbin/ifconfig eth1 down
/sbin/ifconfig eth1 192.168.1.1 broadcast 0.0.0.255 netmask 255.255.255.0
/sbin/ipfwadm-wrapper -F -p deny
/sbin/ipfwadm-wrapper -F -a m -b -S 192.168.1.0/24 -D 0.0.0.0/0


I think it is time to move onto ipchains or the newer stuff... the only problem I have now is if I want to host a game (on 1 of my windows clients in the network), I cannot.

Can anyone write a replacement script that will work like the above and allow me to have a specific port cleared up? The specific is 2234, for Operation: Flashpoint (great game, but make sure you have at least a fully loaded PIII 850 for it).

Thanks ahead, sorry I am such a newb, even though I have been running a masq for years it still confuses me and as much as I read I am stuck.

Output of my ifconfig, just so you see eth0 is the 'real' setup and eth1 is for the internal. (my.ip.is.here is an edit of course, to reduce hacks by people that know even less than me about linux).
