Just use Hamachi or Softether, the VPN applications.
(VPN = Virtual Private Network)
(example:
https://secure.logmein.com/)
Host a VPN network. (add pass)
EQhost.txt should be your Virtual IP.
Tell your friend(s) to hook up into the created network.
eventually, all your friends will need to install Hamachi/softether.
Certificate your friend(s), and get their Virtual IP.
Create account using their Virtual IP.
Done.
Worked fine for me.
Good part is, very easy configuration.
Bad part is, if Hamachi network is down, you're on your own during the weekend.
