Using the Matchmaker System without relay server

Hello,
in ref to my other thread: http://forum.unity3d.com/threads/unet-timeouts.343395/

I want to use the Matchmakting system of unity without a relay server (because the 4 kb/s limit), like the old unity networking system (i need more bandwith for my game).

Or is the only way to build a complete own MasterServer/Matchmaking system ?
