We use a lot of remote kernels at work, and from home to work. The  
configurations we have are Mac to Mac, Mac to Linux, Mac to Windows  
and Windows to Windows. Had trouble with them all until we found this:

"Remote Kernel Strategies"
http://library.wolfram.com/infocenter/Conferences/7250/


It is a useful set of programs to easily connect to remote kernels. It  
has worked beautifully every time. Give it a go, it might work for you.

Regards,

Mark Perrin
