Multi User Editing Connection Issues

Hi, for the past week or so I’ve been going over the various documentation, references, forum posts and anything here on the Answer Hub regarding both hosting and connecting computers using the new multi user editing system. Specifically with trying to have two computers connect from separate countries. I’ve been able to make use of it over LAN, however the issues come when trying to host or join over the internet, or even through a VPN solution to try emulating the LAN setup.

I was hoping the recent Unreal stream showing off the multi user editing might shed some light, but unfortunately it went more over joining someone else, and glossed over the hosting half of things which is where I believe my issue is originating. If anyone has had some luck in this regard, or understands the system I’d really appreciate any insight.

Thanks
