I have maybe the same problem when trying to backup a windows xp laptop 
that is connected via VPN to the backuppc-server.

Unfortunately even when I have established a connection I can not start 
the backup, because I get the following error message:

<TIMESTAMP> Unknown host laptopclient for status request
<TIMESTAMP> User backuppc requested backup of unknown host laptopclient

*** My Setup ***
OpenVPN with IPCop / Zerina
Client IP: 10.128.0.6

backuppc's /etc/hosts contains a line
laptopclient    10.128.0.6

backuppcs /etc/hosts contains a line:
x31     0       backuppc

I also tried to use 1 instead of zero but I get the same error message

*** Tests ***
ping from backuppc to laptopclient is working
ping from laptopclient to backuppc is working


Any idea what could be the reason that backuppc doesn't start the 
backup? The Windows XP firewall is not activated on the client.

Best regards
