you can do it three ways:
1. Download hamachi and create a network, you will need to know your hamachi ip which you can find at the top of hamachi, add this IP into ps_game.ini where it says PublicIP= and then add it in your server config manager where it says GamePublicIP. You will need to have your players download Hamachi too and join the network, make sure to create multiple networks as the networks will get full.
OR
2. go to
and copy and paste this into the same place as i said above. Bear in mind you might have to port forward and shut down any firewalls you have running.
OR
3. The high end option is buying a VPS/Dedicated Server and installing your server on there. Just paste your VPS/Dedi IP into the same place.
