Hi,
 
does anyone know a method to configure the communications between a Veritas
Netbackup master server and a (remote) media server, to be unidirectional
from master to media server only ?
 
We have a firewall sitting between the two boxes, with the master server
sitting on the inside of the firewall, which we consider as 'secure'. The
media server sits in a remote location, and we do not wish to allow network
(Netbackup) communications to originate from 'the outside' media server
towards the 'inside' master server.
 
We checked with SUN, buth they cannot take a firm statement whether this is
possible or not (simply haven't done it yet, is the answer).
By default, the master Netbackup server makes a first connection on
(TCP-)port 13701 towards the media server, which in turn attempts to connect
back to the master server on (TCP-)port 13724. In our setup, this incoming
connection from the media server is blocked by the firewall, and we wish to
keep it like that.
 
Any suggestions are more then welcome !
 
Rob
