I'm going to post my own answer since I actually got to the bottom of
this one. I found the hint on a Link-Sys site of all places.
I changed the address of the router itself & got VPN working. While I
have tried this before without success, the key seem to be in changing
the 3rd batch of digits not the last batch.
In other words, when the default was 192.168.0.1; Change the "0" to
something else, in my case a "2" worked. I used 192.168.2.1 as the
router's own address & VPN pass-through works.
(while using 192.168.0.200 for example didn't help)
I have no explanation of why this works.
