ports and directions for BackupExec through firewall
I am trying to get firewall rules approved for a BackupExec 2012 server to backup servers behind a firewall.
I have configured BackupExec to use 25 ports, and submitted the firewall request to have those ports opened to the appropriate machines.
Articles I've read do not indicate a direction.. or indicate bidirectional, but our security team is concerned about implementing bidirectional access because the servers being backed up are on an externally available network, and the backup server is on an internal network.
Can someone answer definitively if the random ports are required only outbound (backup/media server to client agents), inbound (from the clients to the backup/media server), or in both directions?
Thanks in advance.
