After a few hours of aimless playing, I was able to figure it out. It involves two steps: 1) Make sure there are rules to allow UDP on port 6112 in your firewall rules file. ***Begin snippet*** # Allow me to play Starcraft $fwcmd add allow udp from any to any 6112 out xmit tun0 $fwcmd add allow tcp from any to any 6112 out xmit tun0 $fwcmd add allow udp from any 6112 to any in recv tun0 $fwcmd add allow tcp from any 6112 to any in recv tun0 # Divert all packets through the tunnel interface. $fwcmd add divert natd all from any to any via tun0 ***End snippet*** 2) Use ipnat to direct these UDP ports from your external interface too the internal computer. Yes, this means that only one box behind the NAT can play at a time, and you have to change the port redirections to do that. Here's the line I use: rdr tun0 209.222.79.0/24 port 6112 -> 10.0.0.2 port 6112 udp I use 209.222.79.0/24 because I get allocated an IP somewhere in the that subnet, but I'm not going to get any traffic for any other IPs. SO this is "safe" for me. And "safe" for other dialup IP users. Your mileage may vary. -- Kyle R. Green greek@lagparty.org On Sat, 10 Jun 2000, Kyle R.
