Alright, I'm asking two things here.

First of all, if i purchase a domain let's say myhomeserver.com, am I able to make the default port go through a different port instead of the default port 80? (that is without having to do myhomeserver.com:5000 for example). Also this should be without blocking other ports (so no stealth forwarding to myhomeserver.com:5000 i think)

Secondly, How could I go about hooking a domain to a windows 2008 server? I've seen it on linux but no clue how to do it on windows if it's even possible.

I know I'm asking a lot here, just some tips are appereciated. Also, yes I know, using a home server is horrible for security and preformance and whatnot, I understand this already, thanks ^^
