Making a Private Network

[Manifest0]

Greetings!

I was trying to create a private network, by following the instructions, but unfortunately i wasn't unable to do it...

I've two phex clients, and these were the steps we took:
(my pc was the master pc!)
1*- Both of us went "Network -> Select network" and write "Turbo"
2*- Then I (the master pc) wrote my ip address "Favourites", clicked "add", and "connect". I've got the error: "Connection Refused"
3-* Meanwhile my friend (the slave pc) wrote my IP (the master pc) and clicked on the "connect to" and pressed "Connect". He got "connection refused:connect"

What are we doing wrong?

p.s.: I tried with iptables on and off.... And we both can connect to the gnutella network


edit: I'm using phex 3.0.2, and my friend is using phex (3.0.0)
