Error Internal network accessibility in Microsoft Tunnel Gateway

Question

Hello

I have Microsoft Tunnel Gateway configured in Intune. I use Red Hat Enterprise 9.2 (I only have one server) and Podman 4.4.1

I configured Microsoft Tunnel Gateway according to Microsoft's instructions. I also created scripts checking the system's preparation for installation. The script reports no errors.

However, I have a problem because the phones (Android/iPhone) connect via MS Defender applications, but they cannot access the resources. In health check I see that all statuses are correct, except "Internal network accessibility". I also checked the network traffic between the server and the host to which we want to have access. The host is available directly from the server. However, after analyzing the traffic between the phone and the target host, we see that the traffic goes from the phone to the host but does not return. Did I miss something during setup?
