ipMIDI Setup

Hey all, I am trying to setup my pc and my mac via ipMIDI. Has anyone ever used this program and how do I setup Logic 8 to use the ipMIDI port? What settings do I change in the Logic Control to get it to work? Should I have my midi keyboard (Korg K25) hooked up to my mac or pc? The instruments I want to use are on my pc and I want to transfer the data over to my mac to edit. I know I could just export from my pc and into Logic, which is what Ive been doing, but if I can eliminate a step, I'm not opposed. I appreciate any advice..I'm going to keep playing with it and hopefully I'll figure it out. Thanks!
