If the internal machine that runs Quake is named "brentpc", then
you could use an ipfw rule like this:
# Allow connections to port 27960 for Q3 access to brentpc
$fwcmd add pass tcp from any to ${oip} 27960 setup
$fwcmd add pass tcp from any to ${brentpc} 27960 setup
$fwcmd add pass udp from any to ${oip} 27960
$fwcmd add pass udp from any to ${brentpc} 27960
Or possibly pass tcp from any to ${inet} 27960, etc.
You will also need NAT rules to translate your internal IPs. In
your /etc/rc.conf, include something like:
natd_enable="YES"
natd_flags="-log_denied -f /etc/natd.conf"
Then make a file called /etc/natd.conf, in which you could add:
# for Q3 access to brentpc
redirect_port tcp brentpc:27960 27960
redirect_port udp brentpc:27960 27960
Cheers,
