I also have Connexion.  I also have 443 open for use.  I am allowed to
connect to my port 443 on my Residential dynamic address system okay.
Works for me.

I know your Nokia fiber modem is configured in bridged mode.  In bridge
mode there shouldn't be any filtering.  My modem is still set up in
the default original setup routed mode.  I have my house router
specified as a DMZ.  Which gives me pretty much the same effect but in
a different way.  So I can't say that our setups are identical.

I actually have ssh on port 443.  Because some places, like the PVH
hospital and MCR, no longer allow port 22 out.  Those buggers!  Which
means that I must use port 443 for ssh connectivity.  Because 443 is
https and they just can't block port 443 or it would break the web and
of course they wouldn't be allowed to break the web.  So I piggyback
on that and use 443 for ssh use so that I always have a way out of
those misguided restricted locations.

Port 22 used to work from there but I suspect they changed providers
and with the new came restrictions.  I don't think they are doing this
out of malice.  I think they are just doing it out of incompetence.  I
think they don't even know ssh exists or why anyone might want to use
it and are catering to the unwashed masses of Microsoft and Apple users.
