Maybe a complicated question

Ill try to explain this the best I can 

Currently I'm running 2 instances of HFS. Port 80 and 443 (HTTPS)
I have these set up with NO-IP.com to give it a real name.

I recently bought a domain name (2 actually) with GoDaddy.com.  With this domain I set up google apps email (mail.mydomain.net). I want to create a front page for mydomain.net and host it on another web server on my own machine.

Problem I'm running into is that with godaddy I can add a HostA record to my IP (not sure how to keep it updated automatically when my personal IP changes) but its on port 80. I want to forward it to 8080 so it doesn't conflict with HFS. Is there a way to do this?
How about if in NO-IP.com I do a port 80 redirect for HFS to 8080 and let my godaddy domain go to port 80?

Hope this makes sense, I've confused myself on how to go about this.

A records have no ports, just the IP.
the browser goes to port 80 automatically because it's the default one.
the port redirection is not part of DNS itself, it's actually provided through http.
the DNS points to their machine (not yours), where an http server replies with a redirection to your machine on the desired port.

hope this helps you a bit.

Thanks.
I'm trying to figure out a way to get around this right now so I can host HFS and another Webserver on the same IP. Redirecting HFS to 8080 gives a banner on the bottom of the page from no-ip.com and then HFS 443 doesn't work at all.
