Could someone confirm that the only requirement for a firewall rule for a 
backup of a networker client is port 7937-7941 in both directions. 
 
We have a firewall rule configured and nsrports -s 7937-7941 command run on the 
client. . I can even communicate to port 7937 in both directions using telnet 
but the backup fails.
 
The firewall logs appear to show that ports other than 7937-7941 are being used 
by the backup server.
 
The backup is unsuccessful unless i open the source ports in full in the 
firewall rule.
Our firewall rule has two fields called Low and High under "source port" and 
Low and High under "destination port". If i configure source port to have 
defaults of 1 and 65535 and destination port to have 7937 and 7941 then the 
backup is successful. But the source ports should also be 7937 - 7941
 
Details are:
The client is windows server 2003 networker 7.4.3
The networker server is windows 2003, networker 7.4.3
The firewall is Fortigate firewall  500A Mr6 Patch 3.0
 
Thanks for any advice.
