Thanks, Johnny.  Yes, I'm really trying to focus on the bridged approach 
now.  The script I adapted from Jayjwa *seems* to set up the bridge and 
tap correctly now, and I get connectivity between Pi & DEC20 after 
Jayjwa noted several incorrect settings.  But still no external IP 
connections ... same situation as when I had DEC20 doing point-to-point 
to the Pi eth0 interface.  But once I take the bridge down, external IP 
works again.

I've also got IP forwarding set, thanks to the note from Scott.

But still no joy.
