Hi,
I am working on a multiplayer game and I have some trouble with steam multiplayer and in general with LAN multiplayer over VPN like Hamachi or TeamViewer VPN.
Multiplayer is working on a LAN network. 2 PCs in the same network, using the Session nodes from UE4 or Advanced Session plugin nodes works. But if I use 2 systems connected via Hamachi, they can’t find each other. Anybody any ideas on this? Maybe it’s because I configured the network wrong? Maybe because it’s a different network adapter?
It’s not the game itself. MultiplayerShootout and ShooterGame from the examples are not working too with Hamachi.
Steam multiplayer is kind of working too. The overlay is starting, the console command “open steam.SteamId64” (SteamId64 replaced with the correct id) successfully connected 2 players. However if I try the session nodes (advanced session plugin), on public I will find too many incompatible games (because AppId 480 runs too many test apps I guess) and from friends list it will return the hosted games correctly but with ping 9999, 0 players/0 max players (and connection attempts fail (invalid game session)). And invitations over steam overlay simply doesn’t do anything. I will post some logs later.
If you have any ideas on this, I would be glad to read them. C++ code welcomed too.
