Friends can't connect to my server

[Mattastic]

I have already referred to this guide for setting up a server: http://virtualheroes.com/wp-content/uploads/2012/08/MBA-Dedicated-Servers2012.pdf

I can connect to my server, but my friends can't. I'm giving them my global ip, not my local. All 3 ports are forwarded on my router. I've tried disabling my security and nothing. Any ideas?

I get the same thing, I cant join his server, and he cant join mine, when I send an invite, it always says, Server not responding.

[hee ho]

is universal plug and play available as an option?
