What are the alternatives for bridging DECnet systems across the Internet that don?t

I?m aware of Paul?s Python router, but I didn?t think it ran on a VAX. Am I wrong
about that? Is there a Python for OpenVMS/VAX? I believe there?s a port for AXP but I
didn?t know about one for VAX.
There was, but I think Python recently dropped VMS support due to lack of a maintainer.
It may well be that it could be resurrected; I don't know what that would involve.
Python is a large package but easy to build, so one might hope this could be done. Note
that PyDECnet requires Python 3, version 3.3 or later. It doesn't work with Python 2
and can't reasonably be backported to that version.
And I saw Rob mentioned his user mode DECnet router.
Same questions ? what environment does that require? And I saw mention it being both
Multinet and simh DDCMp compatible ? will it talk to a simh KS10/TOPS10/DMR ?

DMR is DMR, so a PDP10 with a DMR should work. TOPS-10 is Phase IV, right? Any of the
common DECnet implementations should talk to that.
If you have TOPS-20 with Phase II, that's more difficult. PyDECnet does talk to Phase
II directly, but I know of no other Phase IV that does so, and Phase III nodes are not
easy to find either.
