2.3.5 Example of configurations that include a firewall, and their communications settings

(1) Example configuration with a firewall for non-cluster operation, and its communications settings

The following explains a configuration for non-cluster operation in a firewall environment, and the communication settings. The following figure shows a configuration example.

Figure 2‒26: Example of a configuration for setting a firewall in a non-cluster system

The firewall is configured so that data passes through it between hostX and hostA. In this system configuration, there is no need to make any special settings in JP1/AJS3 in addition to the settings for the firewall.

(2) Example configuration with a firewall for cluster operation, and its communications settings

The following explains a configuration and communication settings for cluster operation in a firewall environment. The following figure shows a configuration example.

Figure 2‒27: Example of a configuration for setting a firewall in a cluster system

When the firewall is configured so that data passes through it both between hostX and hostA, and between hostL and hostA, as in (1) Example configuration with a firewall for non-cluster operation, and its communications settings above, you do not have to make any special settings in JP1/AJS3.

In a system based entirely on logical hosts with no physical host services, if a firewall is set up only between hostL and hostA, you must set IP bind as the sending method. For details about how to set IP bind, see the chapter about communication settings in the Job Management Partner 1/Base User's Guide.

Cautionary note

If a firewall has not been set to allow communication between hostX (physical host) and hostA, data cannot pass through the firewall when a queueless job is executed. If you are using queueless jobs, set the environment so that data from the physical host can pass through the firewall.
