UNET - Self-hosted relay server ?

Hello,

Is there an alternative to Unity cloud service for the relay server (to solve the NAT issue) that would be self-hostable and of course compatible with the Unity network API ?
I can live without the matchmaking part, but if there is also something for that, i'm also interested.

I searched in the forum but with no success so far.

A while back, when i was using the old network system, there was this : http://unity3d.com/master-server/
But i guess it's not compatible ?

 

You could give my plugin a try for dealing with NAT issues: https://www.assetstore.unity3d.com/en/#!/content/58948

It comes with a program that is very similar to the old Facilitator, and you can host it pretty much anywhere you want

 

Thanks for your help, but i'm looking for something free
My multiplayer project is not commercial.
(but i'm sure it could help someone willing to pay a little something)
