Hi, after further research from,
I have only just learned that onlinesubsystem=null is LAN only.
There is no clear explanation that i have found anywhere on what is actually required for this simple result:
Open a map as a listen server.
Have someone connect to that map over the internet via direct ip.
I have been told/seen multiple times that ue4 has its own online subsystem, but no explanation on how to access it or what is required to set it up.
So i ask, please someone explain what i need to do in order to set this up.
