Update Firewall Settings

You can configure firewall settings on appropriate Cloud Connector interfaces by working in the Edit Firewall option available on the Action menu.

Before You Begin
  • Identify the Cloud Connector that requires firewall setting updates by name so you can select the appropriate hardware on the Edge Nodes Inventory page.
  • Inspect the firewall configuration items currently set to determine whether you need to remove or add firewall configuration rows.
Context

To choose the appropriate protocol and the port to open using firewall settings, you must understand the nature of the traffic that the firewall needs block or admit. For example, DNS lookup traffic could require the speed benefits of using a User Datagram Protocol (UDP) connection to support faster transmission for a time-sensitive DNS server.

Procedure
  1. Start from a selected Edge Node details page, and click the Network tab.
  2. Choose the interface from the drop-down where you will configure the firewall.
  3. Select the More Action drop-down and select Edit Firewall.
  4. Delete or Edit a firewall entry to address your use case.
    • Remove any previously specified firewall setting rows that should no longer be applied to the firewall configuration by clicking the trash can icon on the associated row.
    • Add a new firewall setting row by clicking Add setting, then click the Protocol drop-down to choose Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) as the protocol.
    • Click Open Port to specify a port number between 1 and 65,535 to open to support the desired firewall operation.
    • Repeat the preceding three steps if you need to remove and add multiple firewall setting rows to address firewall configuration for multiple types of traffic on the network interface.
    • Click the check mark to process the protocol and port changes. The new row displays at the bottom of the drawer.
  5. Click Update to save the firewall settings for the selected network interface.
