Firewall - Troubleshooting

Setup Advanced Troubleshooting Best Practices  

Changes to existing Firewall Settings

After making changes to the existing firewall configuration of a client computer, you must perform the following steps to avoid communication errors.

  1. From the CommCell Console, right-click the CommServe computer, click All Tasks | Push Firewall Configuration.
  2. Right-click the MediaAgent computer, click All Tasks | Push Firewall Configuration. Repeat this step for all applicable MediaAgents.
  3. Right-click the client/client group, click All Tasks | Push Firewall Configuration. Repeat this step for all applicable client computers and/or client groups.

Reconfigure Incoming Ports

If you change the incoming ports of a client computer already configured with firewall settings, you may need to restart the client services for the new configuration to take effect.

See Service Control for more information.

Connectivity Loss between CommServe and Client during Firewall Configuration

Scenario 1

When configuring firewall on a client computer, you may lose connection between the CommServe and the client being configured. If Push Firewall Configuration fails to update the client and returns a communication error, follow the steps below:

  1. From the CommCell Console, right-click the client computer just configured and click Properties.
  2. From the Firewall Configuration tab, click the Summary tab and copy its contents to the fwconfig.txt file located at the <software installation path>/Base folder.
    Recent changes to the firewall configuration of a client computer are reflected in the Summary tab. Unless you use Push Firewall Configuration, the client will not be updated with the latest changes.

The client is updated with the new firewall configuration.

Scenario 2

When you change the name of a client computer, the connectivity between the client and the CommServe may fail. After performing the name change on the client, right-click the client computer from the CommCell Browser and then click All Tasks | Push Firewall Configuration.
