uvrpcservices permissions are promiscuous, an asterix for allowed hosts (and a bright red lipstick color on the file name...).
So... questions include: would this hose uvnet (the error is "unable to open uvrpcservices")? Is there a way to configure uvrpc to accomodate devices like this NAT? And, just out of curiosity, what is the mechanism that uvrpcservices uses to establish the connection? Does it look at the packet header? Is there in fact a return address in the packet data?

Hi, David. I've been testing your suggestion for the past couple of days.
Selecting "allow this service to interact with the desktop" does indeed
somehow keep the service alive (and I suppose I can live with the DOS window
that pops up whenever a connection is made...)
Thanks for the information!
