RealVNC questions about ports and display number

James,

I'm willing to buy your last conjecture.  I know how to do port
forwarding properly and my other gizmo works fine with port forwarding
over wireless.  I assume VNC has some other subtle requirement which
the damn router does not implement.  I didn't mean to complain about
the VNC, I just meant to complain about the retail routers and maybe
find out about at least one model that works.

Thanks a lot!

Dragos
