In lieu of login server code and in the interest of making vpn set up easier.
www.hamachi.cc
Very easy to set up.
Everyone gets their own IP address and joins a private network that you can set up and password protect. Your eqemu server must run hamachi and join the network too. Then you bring up hamachi, and point your eqhost.txt file to the hamachi ip address of your server.
Since everyone gets their own hamachi ip address, you can use mini login and each person has their own minilogin account with their hamachi ip as the minilogin ip.
It's encrypted, private, and fast. I've used it to connect to my eqemu server. Works very well.
