Hi michaelsaw,
Thank you for your reply.
Yes, a ticket has been opened with support and it has progressed to Tier 3. I posted here to see if there are any admins or partners experiencing the same issue and if anyone has been able to resolve it.
Always-on is set correctly according to the procedure in the Learning Center, and the user's Cato Client is 5.4 or 5.5.
Distributing Device Certificates to macOS and iOS Devices with Jamf
The point of the problem is that Cato Client adds an on-demand VPN configuration automatically after authentication is complete. (It was not a profile.)
This results in two VPN configurations, one added from MDM and one added by Cato Client, and by the user switching between them or deleting the on-demand VPN configuration, unmanaged Internet access becomes possible.
Thank you!!
