Starting the SmartFox Tutorial

I’ve been trying to get multiplayer working for quite awhile now and, I can’t do it!
http://www.unifycommunity.com/wiki/index.php?title=Multiplayer_with_Unity_and_SmartFox_tutorial

Here’s a link to one of the various tutorials using Smart Fox I have tried.

Now I can set up my Unity files fine but when it comes to actually running the .EXE and connecting two computers I can’t figure it out.

Could anyone possibly explain to me how to get the two computers communicating;
Does Smart Fox need to be running on both comps?
Is the server IP the same for both computers?

Anything I need to know could someone please clarify!

Thanks!
