sorry for my english.

I want to create FPS game or game have to create room(Client can create room without forward port). Now i use master server of unity. But it can create one room or one server. It can't Initialize multiple servers.
My idea.
Step 1 Server run
Step 2 Client create own room (without forward port)
Step 3 Server show room(name C1) and all room(C2,C3,...Cn)
Step 4 Client other choose join to room as join to C2
Step 5 Play
My question.
1.TNet can create Initialize multiple servers?(On one server)
2.If i use TNet. Client can create own room without forward port? (most important. Because i don't want to give client forward port. If client have to forward post.Client feel enjoy. Because some client don't know about forward post.)
3.TNet have tutorial? (form 1 and 2) i search form youtube. I see three clip.
If one and two TNet can do. I'll buy TNet.

Thank you.
