Microsoft Defender for Endpoint Windows 11 versus Windows 10

Hello,

We have set up the following firewall rules which work perfectly on Windows 10 but not on Windows 11 :
Public/private profile :
- Inbound - block
- Outboud - Allow
Domain profile :
- Inbound - block
- Outboud - Allow
- Rule : Any-Any - Allow

When the Global Protect VPN goes up, we change the profile to ‘domain, private’.
And no more flows go through.

Why is there a difference in behaviour between Windows 10 and Windows 11?
How can we address our use case?

Best Regards
