Thanks for the very helpful responses such as this.

I am trying to secure my machine by using a firewall, and I want to use
something reliable like the built-in Microsoft Internet Connection Firewall
in XP. I tried to enable it and then unblock the various ports that I am
using, but I couldnt get it to work. Even though I would unblock port 80,
for instance, the web server was not accessible anymore.

Any idea why this is happening?
