I am running a Ubuntu Server 13.04. I use it as both a Webserver and a Minecraft Server. My cable company does not allow port 80, so I got a free re-direct from no-ip.com. It redirects to 24.255.213.250:50005 which is what apache2 is listening to. I have set the redirect name to dlzpserver.no-ip.info. If you click on that you will see what I mean, it changes the URL to 24.255.213.250:50005 instead of keeping it at dlzpserver.no-ip.info. Anybody have any ideas how to keep it on dlzpserver.no-ip.info as you are exploring the website?

You can't do that. the nice (ish!) name points to the noip servers, not to yours. they are not proxying all your traffic for you, just giving back an alternative URI. and you can NEVER get rid of the port number unless you have a reverse proxy goign on somwhere, which is a significantly bigger issue than a simple redirect service. All you can do is make the redirect service redirect to a nice name for the server itself, so dlzpserver.no-ip.info could send you to dlzpserver-origin.no-ip.info:50005 or something, but that's as good as it will get.

:/ Ok thanks I guess. So there is no setting on the server that I can change for that?

No, that just doesn't make sense. I'd suggest some background reading on what you've actually got, and not got, to see why it's illogical.

Ok thanks.
