New installation - Master server - running as a cluster on W2K8 R2. Media server - W2K8 R2. Both have the Windows firewall enabled. Running the media server install get the "Unable to communicate with Master" popup message. Continue on with the install - the media server does not show up in the EMM database unless i manually add it. Disable the Windows firewall on Master/media - the install works flawlessly. I have updated the Hosts file on both ends - master and media can ping each other and resolve via DNS.
Re-enabled the firewall on media server and added the following rules:
Inbound - allow ports: 1556, 13724, 2821, 4032, 13782
Outbound - allow ports: 1556, 13724, 2821, 4032, 13782
Re-enabled the firewall on the master and added the following rules:
Inbound - allow ports: 1556, 13724, 13783, 13722, 13782, 2821, 4032
Outbound - allow ports: 1556, 13724, 13783, 13722, 13782, 2821, 4032

Re-attempted the Media server install - still get the "Unable to communicate .." error message. I validated that the master server was listening on the ports via telnet and netstat.
I then installed a protocol analyzer on the Master - re-attempted the install and captured the traffic up to the point of reaching the summary page during the install. Here is what i found:
Source (media server) ports: 57077, 57078
Destination (master server) ports: 13720

I have read and re-read the Symantec Netbackup Network Ports Reference Guide Release 7.6 ... as well as the Technote Symantec Support forwarded and nowhere can i find any mention of ports 57077 and 57078 - nor any indication of a dynamic range that would include these two ports. Unfortunately, i cannot leave the Windows firewall disabled on the servers. Any ideas?
