Bill
I have ipfw with 'allow log from any to any'  so I can see all the traffic.
I have no proxy server. The game I am playing is Delta Force from Novalogic.
When the game goes into internet player mode the fileewall log shows my lan
win98 pc issueing request on port 80 to the delta force game server and the
game server responding with port 80. The win98 pc keeps sending the same
packet
and receving the same packet over again and again, but nothing happens.

Which game? Different games function in different ways, and the answer
may be different or there may be no solution, depending on the game.
We've played UT-tournament, freeciv, and Everquest through a natd firewall
with no problems, so in many cases, it is possible.

Could be.  Try using Ethereal or another packet sniffer to determine what
exactly is going on with the proxy.
If you have a firewall running, examine the logs to see what's being
blocked.

You can't.
