I encountered the same problem several years ago when I had a loo into 
OpenVPN. What I found at that time was that no such thing existed. It is 
not impossible to create them, but for that you have to write a 
devicedriver. Probably you need some insight knowledge of OpenVMS for 
that which is not in the "general" manuals.

The devicedriver should mimick on the OpenVMS site just an 
internetdevice and route all the trafic on the backsite to the physical 
internetdevice.
