In my opinion from what you have stated, your "phyical" firewall is defective.

I have firewalls between many of my clients and my NetWorker server and storage 
nodes.  I have
my customers configure their clients to force the to use server ports 7937-7940 
(still only
need four on the client side) tcp and 7938 udp, and the firewalls are 
configured to allow my
NetWorker server to connect to those ports.  The way NetWorker winds up 
working, the client
initiates the connection to the storage node(s) required, so everything that 
happens after the
backup is initiated is covered by the "ESTABLISHED, RELATED" category which 
every firewall
should have.
