BB through a VPN?

Maybe this is OT?? Not sure, so I'll try anyway.

I'm using my laptop at home, connecting to my work through the company's 
VPN.
Running the backburner manager on my laptop, the server on the work/desktop 
computer will find it no problem.  The problem is when the work/desktop 
computer tries to render a job.  The scene has a number of material maps and 
they all use the UNC pointing back to my laptop.  The desktop/work computer 
will fail the rendering because it can't find the laptop computer.  Could 
this be a restriction on the VPN?
