I've run a test synthetic backup and received the following error:

14/12/2011 16:34:21 - Error bptm(pid=4476) synth writer cannot connect to synth job on host=tedc-nms-nbc01 and port=58547, error=A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

I assume it's because the relevant port isn't open in the firewall between the Master (Windows 2008 Cluster, Netbackup 6.5.4) and Media servers (Windows 2008 Std, Netbackup 6.5.4). Can someone confirm what port needs to be open for synthetic backups to run correctly (looks like port 58547 but want to confirm it)

Thanks
