Manage access with the Firewall tool

Use the Firewall tool to create, view, and edit a PI Firewall. The PI Firewall is a security feature that allows the PI Network Manager to control access to Data Archive at the IP network address level. System administrators can use the PI Firewall to allow or deny specific computers to connect.

You can use the PI Firewall to temporarily deny all access to a Data Archive server. For example, you might want to use the PI Firewall when you upgrade a primary Data Archive server within a collective. In this case, you can ensure that users and applications will connect to a secondary member within the collective, not the primary, while you upgrade and test the Data Archive server.

Note: In the default Data Archive configuration, the PI Firewall allows connections from all possible client addresses. Create a PI Firewall to control access to a specific computer.
