Just to check that I understood your setup correctly, the machines are 
arranged something like this?

[bbackupd client] -- [internet] -- [NAT router] -- [bbstored server]

with the NAT router forwarding port 2201 to the bbstored server? That 
should work.

And you can telnet, on the client, to port 2201 on the NAT router, and you 
get connected to the bbstored server? (which tries to speak SSL to you)

Please could you try requesting a sync with "bbackupctl sync" while 
running bbackupd with -DVT and let me know what bbackupd says?

bbackupd stores temporary state files in there: the last_sync_start and 
last_sync_finish marker files (which are not necessary for Box Backup 
operation, but may be useful to admins) and the inode map, which is used 
to track renamed files.

Cheers, Chris.
