Hi,
It should be possible, though I haven’t tried it myself yet. You could check out this guide: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums . The kit also has a separate C# chat server with source code included, it would also need to be built for Linux.
I’m not familiar with NoIP unfortunately, so can’t help you out with that. Myself, I prefer to use my local machine for personal testing only and to order hourly or monthly hosting for projects that need to be accessed by other people over the internet.
