Please cover alternatives to the Steam god.
Hamachi, etc. 
If Hamachi or other NAT punchers doesn’t work with latest versions of Unreal please tell us.
( I sat for 3 days trying to get Hamachi to work with Unreal and despite everyone’s advice on forums I couldn’t get it to work ).
Also if you want to host from a public WiFi hotspot such as a coffee shop is it possible?
How can port forwarding be dealt with if hosting from a public WiFi hotspot?.
Problem is you cant have Admin rights to public restaurant’s router so port forwarding cant be done.
Is there a way around this?
Also even in a private residence if your WiFi is shared by other tenants the landlord might not want to give you Admin rights to log into router this is a problem I ran into with one of my friends I couldn’t find a way around this issue.
Also Unity for a while had its own servers / NAT puncher system and then they discontinued that. Can you guys tell us why they stopped that / what the issue was I am just curious to know how Steam can get around that and they couldn’t.
Also if Epic is working on a MP server system / NAT puncher that we as indie developers can use please tell us that would be awesome news and something to look forward to :-))))))
TY
