FYI... I was having problems getting port forwarding to work with Microsoft Vista.
I was using the default port value of "88" in the port forwarding table in my router but I still could not access the services on my server from anywhere on the network.
Since I'm using the Vista O/S on the server and it has it's own native firewall software I found that it had an entry for the NCH "Broadwave Web Server" but for some reason it was opening up port "85" by default, not port "88"!! Most of the exceptions in the firewall list is associated with the software's executable file, but NOT with
