Configuration Example

The example network in the next figure Master to Media Server and Clients Example, shows a master server in a private (internal) network that is inside a firewall. The clients and media server are outside the firewall. To meet the port requirements shown in this figure, you must configure NetBackup to:

• Limit external connections to NetBackup in the private network by allowing the master server to accept reserved connections only on ports 923 through 1023 (the default is 512 through 1023).
• Limit NetBackup connections out of the private network by allowing the master server to:
• Use only ports 4900 through 5000 for nonreserved-port connections to the clients (the default is 1024 through 5000).
• Use only ports 923 through 1023 for reserved-port connections to bpcd on the media server (the default is 512 through 1023).

To configure NetBackup, perform the following on the master server (no changes are required on the media server or clients):

1. Add CLIENT_RESERVED_PORT_WINDOW=923 1023 to the bp.conf file.

   This specifies the reserved ports that the master server can use to originate connections, including those to bpcd on the media server.

2. Add CLIENT_PORT_WINDOW=4900 5000 to the bp.conf file.

   This specifies the nonreserved ports that the master server can use to originate connections, including those to vopied on the client.

3. Add SERVER_RESERVED_PORT_WINDOW=923 1023 to the bp.conf file.

   This specifies the reserved ports where the master server can elect to listen for connections.

   The master server chooses from this range when it specifies the ports where it will listen for call back connections from bpcd).
