Most servers, personal web servers or businesses can use a variety of ports, 80, 8000, 8080, 8001 or just about anything you choose to use or setup your personal or business server. AHP is not a "stand alone" server as is, however when used with the My House plug-in for AHP you can set it up to connect to it remotely and operate your cameras and other devices remotely. My House connects to a server at X10, which provides you with an access code for remote logon to your AHP at home or work or where ever you have it setup at. You then go to a specific website,
http://myhouse.x10.com?########## and enter your username / access code to connect to your AHP setup and your all set. You're actually using X10's web service / server as a portal to connect to your computer running AHP.
