I've got a Linux machine as my Internet Gateway, Firewall, WebServer, etc. And also have Win2003 on the internal network, aswell as an XP box. I have a static external IP, and have setup port forwarding to my Win2003 machine running IIS. From my internal network, I can access the Win2003 webserver no probs, but when trying from the Internet, i get connection refused. I have ZoneAlarm installed on the Win2003 server, and see the connections coming in, so it's not my port-forwarding rules on the Linux machine. But even if i disable the ZoneAlarm firewall, i still get the connection refused. as an example, from my XP machine (192.168.1.3), if i use a web browser to view 192.168.1.2 (Win2003) it works fine, but 192.168.1.1:8280 does not. My linux server is 192.168.1.1, and port 8280 has been forwarded to port 80 on 192.168.1.2. Like I say, i see the connections come into Win2003 when trying 192.168.1.1:8280, so i'm sure that's not the cause. Any idea's?

Why did you install zoneAlarm on the server for?

To check if the connection was actually getting through to the Windows server, not had much experience with Windows servers, but I know ZoneAlarm well from using it on my XP box, so i knew i'd be able to see if anything was coming through.
