Bind Server IP

Hello,

I have some troubles with photon bolt. I'd like to host the server on a client (MasterClient ?) and so others clients will connect to him to join the game. I tried many things but it's not working.
I've seen something with Zeus server, but I don't really know how to use it with external IP.

Does someone can explain me or can give me a tutorial about this ?

Thanks for your help.
