Workflow to enable NAT hosts in NetBackup domain

The following table provides the workflow to enable NAT hosts in a NetBackup domain.


Install or upgrade NetBackup	Install NetBackup 8.2 or later software on the master server, media server, and client computers or upgrade the existing software to NetBackup 8.2 or later.
Prepare master server for NAT support	Do the following: Configure the NetBackup Messaging Broker (or nbmqbroker) service. See Configuring the NetBackup Messaging Broker service. Set the INITIATE_REVERSE_CONNECTION configuration option to TRUE on the master server using the nbsetconfig command. Restart the master server services.
Prepare media server for NAT support	Do the following: Set the INITIATE_REVERSE_CONNECTION configuration option to TRUE on the media server using the nbsetconfig command. Restart the media server services.
Prepare NetBackup client for NAT support	Do the following: Set the ACCEPT_REVERSE_CONNECTION configuration option to TRUE on the client using the nbsetconfig command. Restart the client services. In case of silent installation, you need to set the ACCEPT_REVERSE_CONNECTION option in the answer file only once so that the configuration takes place simultaneously for all clients. For UNIX, ensure that the NBInstallAnswer.conf file is updated with the ACCEPT_REVERSE_CONNECTION option. For Windows, ensure that the silentclient.cmd script is edited with the required information about the ACCEPT_REVERSE_CONNECTION option. For more information on the silent installation, refer to the NetBackup Installation Guide.
