Assistance Needed for Dual Tunnel Setup in Transition from Windows AoVPN RRaS to Fortigate

Hi FortiGate Community,

I'm considering replacing the current Windows AoVPN RRaS I have with a solution based on FortiGate. I aim to set up both a device tunnel (which connects before user login) and a user tunnel (which connects after user login).

So far, I've successfully configured the device and user tunnels separately. However, face issues when trying to run both tunnels at the same time.

Has anyone here successfully switched from Windows AoVPN RRaS to a Fortigate setup with both these tunnels? If so, I would really appreciate any advice, tips, or configuration steps you could share.

And any best practices that are important for this setup?

Thank you.
