torifle, if you ever get it to work can you post a tutorial here..
Or perhaps you can Yontsey.

I have a PBG4 as our houses base station, and everything shares off that wirelessly.. My 360 is running off the back of my Wife's Mac over ethernet.

XBox Live and so on all work fine. Never had an issue, but Connect360 just doesn't even see my 360 from any machine!

EDIT - The only time I have ever seen that other firewall message on my Mac has been twice. Once was when I did foolishly for a microsecond have Norton on my machine, and had that firewall on, even though I had selected it to be off. Fucking Norton!
The other was whenever I had VPC running. I have not noticed it with Parallels, but do you have Parallels, and is it running?
