There is a good guide over here, at http://pokerealm.com/articles/server-setup.php
and for the last step, you can manually ( I prefer this ) forward 5080 by going into your Router's setting, which is usually found at 192.168.0.1 or 192.168.1.1
and to log in, the user/pass is usually something like, User/User, or Admin/Admin.
Then you go in port forwarding, put in the IP address you got by using /ipconfig all where it is, and put 5080 for the ports.
I prefer this as it is a good free alternative
