Dedicated Win2003 COD4 Machine behind ISA 2006 Firewall

[tangmonkey]

I have a pretty fast Win2k3 server behind a Microsoft ISA 2006 firewall, and I can't for the life of me get it working properly. I've forwarded all the ports recommended, but it still wont work. The server works just fine if I expose it directly to the internet, but for security reasons, I really don't want to do that, and I have to have it behind the firewall.

Any insight would be helpful.

Do I have the ports right? Is there some special setting in ISA?

These are the 3 ports needed I believe.

UDP 20800, 20810 and 28960

yea i figured it out...ISA deals with UDP ports differently than most other routers/firewalls. When opening the port you a presented with several different options and I had to create two different rules for ISA.

Publish rule:
Port 28960 UDP Receive Send

Access rule (Server to External):
Port 20800 & 20810 UDP Send Receive

Hi,

Anyway you could explain how? I've tried, but no luck.
