Master Server rules annoy me, no thanks =)
Aaaaaaaaaanyway, I know what this dude's talking about. I use it too. It creates a virtual LAN network which I guess is called WAN like Jazz said. I do it with Hannyness, Metalsonicmk72, and a lot of others who either don't come here anymore or just don't want to join. Believe me, I doubt you'd like them anyway.
