Actually, that is a little hard to tell. The way I set it up, the tunnel 
will remain open for a minimum of 1 minute - to give bacula enough time 
to initiate contact. After that, with my setup, the tunnel would 
disappear immediately when the last connection closes.

I can't tell exactly when the tunnel disappears, but it happens fairly 
shortly after this initial one minute. There is activity through the 
tunnel before that point.
