- You need to find your computer's ipv4 a dress and use that instead of 127.0.0.1
- you have to port forward (open ports) of every port being used by your files. ( the port: #### from gameserver.cfg, accountserver.cfg,group and so on)
-- to open the ports you need to find out what router /isp you are using and log into that routers website to open the ports along with making exceptions in your firewalls.
-- every router is different so you will have to Google how to access your specific router / get the login information for it.
Alternatively you can host it on a Windows vps, wich usually has most of this work done for you.
Or you can download and use hamachi if its just for your friends.
