it is pretty much simple mate , all you have to do is create a c line with the ip from your box with the cline ( server ) & give name & password .
example= C: 192.168.1.3 12000 me me1 , put this in the 2nd box ( client ) & put this F line in your box with the cline ( server ) = F: me me1 { 0:0:2 } .this should do the trick. you will also have to open a port on your router for your server with the same ip as the server.most people use port 12000.
your f line should be like this mate eg, in your server
F: username password { 0:0:2 }
your c line should be like this in your client box ( bedroom )
C: ******2.no-ip*org 12000 ******8* **************2 { 0:0:2 }
