Help with EP3 to go online

Hello,

I want to make an EP3 server to PvP with some friends.

I have downloaded EP3 server files I've found on the internet, installed everything on a Centos 6.10 computer.

The problem is that I can log in succesfully from any computer on the same network with the server, I have forwarded all the ports on my Router, but cannot still connect from outsider, I can log in, but in the momment I chose a server, I get "Failed to connect to Game Server." dialog.

I've been looking on all the logs, and when I try to connect from outside of the network, it does not even open a socket.

Any ideas to fix that? I don't want to use Hamachi

Is it running on a real computer with centos or a virtual machine? Because in a virtual machine it won‘t work that easily

Running on a real computer.

Centos 6.10 (64 bit)

I've gbeen looking and I cannot conect because it looks for my local IP on internet instead of my external.
Probably i missconfigured something on a newStobm, could anyone help?

use 127.0.0.1 for all but game server and login server, for these two you add your external ip

What about using hamachi connection? EP3 is actually dead as server version, but if you only need to stay with some friends, you could use an hamachi network, and reg all people in a room :D ( my advice is to not open all your port or use your own ip )
