Hi i recently setup a small webserver at my home for my small website for my cousin and my brother and I because i can't afford a host that has ASP, ASP.net and other features. Anyways that doesn't really have anything to do with my question, my problem is i had to use 8080 to get it working right. Unfortunately that was the port my linksys router used. So i think i changed it (I think i don't remember) unfortunately i don't remember what it is now. So is there some kind of port scanner that I can download to scan my network and find out which port to use?

Nmap. Or you could reset the router. Since you're using an arbitrary port for your webserver, it might be easier if you used a different port for that and just let the router's admin interface remain on its default port.
