Can't access server from internet.

[Jk]

What I can do:
-access server from other computers in my network at http://server/
-use phproxy on my server at http://server/blah
-use torrentflux-b4rt at http://server/torrent

What I can't do:
-Any of these things from the internet.

I used this tutorial to make a server with kubuntu, apache2, mysql,
Tutorial

I used a free no-ip.com host name named "jkay.servebeer.com" and installed the dynamic ip software on my computer. From what the tutorial says I can just enter in jkay.servebeer.com and it should take me to my server. Instead I get an error "could not connect to remote server"

I googled and most problems were solved by forwarding port 80, but my port 80 is already forwarded on my router. Google also said to try a nslookup, when I try it I get my ip adress so I guess no-ip.com is working on their side.

Any Ideas or is there anything else I can provide to help diagnose the problem?
I'll upload some pictures of what I see in a little bit.

Thanks in advance!

Edit: Nevermind I think I found out why it doesn't work. I can't access the website from inside the network. I tried outside of my network and it worked. If anything comes up I'll post back.
