Hi Jerry.

I've had similar problems with trying to use VNC thru a vpn with ZA
running on my PC at home.  What I think I finally did was add both
the external ip address of my work firewall and the internal address
of my work pc to the 'local' ip list in ZA.  I believe this cured the
problem (although I'm not really sure why...)  Since you're behind
a router, this isn't an additional security risk as long as you've
got your router buttoned down.  If you were running ZA alone, with 
no router, then I would be a little more hesitant to do this...
