[Box Backup] bbstored/bbackupd communication ports

I think I understand now. bbstored binds to a specific IP address, not to 
localhost. So you can't (on homeserver) run "telnet 127.0.0.1 2201" but 
you can run "telnet homeserver 2201". Thus, SSH also needs to connect to 
the IP that bbstored is bound to, not to localhost. You can confirm this 
with "lsof -lnp | grep bbstored" on homeserver.

Most services will bind to "any address" (0.0.0.0), thus you can connect 
either to localhost, or the private IP(s) of the server, and it doesn't 
make any difference to them. That's why IMAP etc. worked but bbstored 
didn't.

Sorry I misunderstood your network layout, it's late and I'm tired.

Cheers, Chris.
