On the Global Settings tab you can enable or disable the support for RED which means that your Sophos UTM acts as a RED hub. You need to enable the RED support before any RED appliances can connect to Sophos UTM.
- On the Global Settings tab, enable RED.
Click the toggle switch.
By default the settings from the Management > System Settings > Organizational tab is used.
Click Activate RED.
To cancel the configuration, click the amber colored toggle switch.
When RED support is enabled, you can specify if disconnected RED appliances should automatically be deauthorized after a certain time span. With this feature, you can prevent stolen RED appliances from connecting to Sophos UTM.
Note –The Automatic Device Deauthorization does not work for RED Tunnel between 2 Sophos UTM units.
Enable automatic deauthorization.
Select the Enable automatic device deauthorization checkbox.
Specify a time span after which the RED appliance should be deauthorized.
Enter the desired value into the Deauthorize after text box. The minimum time span is 5 minutes.
The automatic device deauthorization is now activated.
When a RED appliance reconnects after being disconnected for a time span longer than the defined time span, it will automatically be disabled. This is indicated by the toggle switches on the Client Management page. A respective warning will be displayed on the Overview page as well. To permit a deauthorized RED appliance to connect again, enable that RED appliance on the Client Management page.
Disabling RED will not cause the deletion of the REDs. If you disable the RED functionality the RED devices will be deactivated and lose their connection. If you re-enable the RED functionality of Sophos UTM the REDs will be activated again.
To disable RED click the toggle switch on the Global Settings page and confirm by clicking the Confirm removal of RED configuration button.
