[Sophos Notification] Advisory: Sophos UTM - RED Site-to-Site tunnel issues after upgrading to v9.7

Hi Community,

Sophos is investigating reports from some customers experiencing RED site-to-site tunnel issues after upgrading from v9.605 to v9.7.

The development team is actively investigating to release a fix for this issue.

In the meantime, any affected customers can workaround this issue by re-downloading the provisioning file from the Server, and re-creating the client-side RED-interface:

• On the Server
  1. In the Admin UI, go to: Red Management > [Server] Client Management
  2. Download all necessary provisioning files

• On the Client
  1. In the Admin UI, go to: Red Management > [Client] Tunnel Management
  2. Open the affected RED-Device and take note of the Tunnel Name and UTM Host
  3. Delete the Client Tunnel
  4. Create a new tunnel using the above noted Tunnel Name,UTM-Host, and downloaded provisioning file.
  5. In the Admin UI go to: Interface & Routing > Interfaces 
  6. Open the affected Tunnel Interface and select the newly recreated RED-Interface

KBA 134717 has been published and will be updated when more information becomes available.

Regards,
