For what it's worth, I recently split my DIR and SD boxes with a firewall (and 
a very slow link, as it turns out...).  I was having all kinds of timeout 
issues, usually with the connection from DIR->SD while data was being sent from 
Client->SD (for many hours).  Heartbeats did not help, but changing the TCP 
Keepalive timeouts (as mentioned in the FAQ; 
http://wiki.bacula.org/doku.php?id=faq ) worked great.  I only set it on DIR 
and SD boxes, no need to set it on Clients.  Changing it on the SD keeps my 
Client->SD connections alive, while DIR keeps DIR->Client connection alive; 
both ends keep DIR->SD alive.  Some of my jobs trickle in for 48 hours, which 
is certainly not ideal, but we needed offsite disk-based backups of large 
files...

Servers are Debian 5 (Lenny) running 5.0.2, firewall was Juniper Netscreen.
