Are you planning to have it speak unencapsulated, too?   That would be
nice for talking to real DECnet nodes.

someone
tell me how Cisco and Multinet encapsulate DECnet packets sent over
the internet?


Thanks

Yes, that should be the simplest one. For that I am assuming that the
router would be connected directly to the Ethernet segment, not
missing anything am I?

Right, that's what I had in mind.   An Ethernet segment with a PDP11 on it
along with your creation.

Extra credit would be support of point to point links... which I could
actually
use, since my current PDP11 speaks DDCMP but not yet Ethernet (no driver
for its NIC yet).   That's off the wall enough that I wouldn't expect you
to do
it, but I would probably take it on as an additional feature.

DDCMP over some kind of serial line? Would need appropriate hardware and
driver code to work against that.
