I’m not yet a wizard with networking as I haven’t required it so far, but people recommend this document on networking:

Multiplayer Network Compendium | An Unreal Engine Blog by Cedric Neukirchen

While my first thought was also GameMode or GameInstance, this document talks about an entirely different approach.

Page 94 would suggest you might want to take a look at the “Online Subsystem” and how a session is configured. Page 88 shows that it’s goal is to make it all work with various consoles and online platforms.
