Adding Web Isolation Profile from FortiProxy to FortiIsolator

FortiIsolator supports adding a web isolation profile from FortiProxy to FortiIsolator.

FortiIsolator setup

Download FortiIsolator CA Certificate
  1. Connect to FortiIsolator
  2. Go to Dashboard > System Information > Isolator CA Certificate > Backup/Restore.
  3. Backup the CA Certificates by pressing Click here. Save the ca.tgz file to your local system
  4. Unzip ca.tgz, you get 3 files under a new folder; these files will be use later when configuring FortiProxy.
Configure Default Policy
  1. Set the Guest Type to guest only.
  2. Set Default Isolator Profile Name to system_default.
  3. Click OK.
Note

FortiProxy Header content must be named consistently with the FortiIsolator Profile name that is selected in FortiIsolator Default Policy setting.

Currently the profile name "system_default" is being used in the example below. All settings, as in FortiProxy header content, FortiIsolator Isolator Profile Name, and FortiIsolator Default Isolator Profile, are using the same profile name "system_default."
