I installed Abyss Web Server. I'm running Windows XP Home Edition and I have Wireless Mobile Broadband internet.

I used to be able to access (and other people on other networks) my site by entering my IP address in the browser, but after I formatted, and installed Abyss web server again, this does not work anymore. 

There are no errors. I CAN visit my own site by entering my IP address, BUT anybody else can't do the same - it just says "connecting" in the browser's status bar and it never changes.

I have consulted the docs and have found no help. Google hasn't helped with this problem either.
