Configuring an L2 exception list

In some jurisdictions, SSL interception and decryption is disfavored for some types of websites or disallowed entirely. You use the L2 Exception List configuration to define such destinations. You can leverage FortiGuard web filter categories, and you can configure a list of additional destinations.

Before you begin:

  • You must have created a Web Filter Profile configuration that includes the web categories to exclude from SSL decryption.
  • You must have hostname or IP address details on additional destinations you want to exclude from SSL decryption.
  • You must have Read-Write permission for Load Balance settings.

After you have created an L2 exception list configuration object, you can select it in a Layer 2 virtual server configuration.

To configure an exception list:
  1. Go to Server Load Balance > SSL-FP Resources.
  2. Click the L2 Exception List tab.
  3. Click Create New to display the configuration editor.
  4. Complete the configuration as described in L2 exception list configuration.
  5. Save the configuration.
