Network and port address translation

NetBackup 8.2 and later versions support NetBackup clients in a private network that are connected to NetBackup servers in a public network through a device that performs network address translation (NAT). Such NetBackup clients are referred to as NAT clients.

For more details on NAT support, refer to the NetBackup Administrator's Guide Volume I.

NetBackup 8.3 and later versions support media servers in a private network that are connected to the primary server in a public network through a device that performs network address translation (NAT).

The TCP port used by the NetBackup Messaging Broker (nbmqbroker) service must be open from the clients to the primary server. The default port is 13781 unless it is updated with the configureMQ command.

Note that the direction of connection initiation between servers and clients is reversed. The TCP port for PBX/1556 must be open from the client to the servers and need not be open from servers to clients.

For additional details see the article NetBackup support for NAT and PAT.
