[wplug] Newbie Iptables question.

[Kubbie]

I am trying to Host a game from a XP machine behind a Slackware
firewall/DHCP box.  However, my game is not being seen by those trying to
connect.  The game requires ports 2302-2304 UDP  to Host a game and ports
2300-2400 UDP to be open for normal game play.  I may not have type the
iptables in correctly.
What would be the correct command string to enter to let this machine
(10.x.x.x) host through the firewall?

Thanks in advance.
