Well, it works when I'm just connected with a laptop.  That proves (to
them) that it's not their equipment.  It could be my equipment.  It
could be a bad interaction between..  It's very hard to say.

The problem is my static IPs.  I can't just replace the modem.  And I
can't just "take a random IP address" because it requires coordination
to also migrate my tunnels, which is how code.gnucash.org gets its IP

I have a /29 from them.

Alas, Cambridge is about 1000 miles from here.  While I DID live in
Somerville for ~14 years, I'm now much further south ;)

PS: There is still a SMALL chance that it's not my VM system..  I'm
considering taking it offline again this afternoon to test it again.
