- question: |
I'm encountering TCP fragmentation issues, and cannot enable my VPN connection. How do I fix this?
answer: |
WinNAT drops ICMP/UDP messages with packets greater than MTU when using Default Switch or Docker NAT network. Support for this has been added in [KB4571744](https://www.catalog.update.microsoft.com/Search.aspx?q=4571744). To fix the issue, install the update and enable the fix by following these steps:
1. Ensure that the FragmentAware DWORD is set to 1 in this registry setting: `\Registry\Machine\SYSTEM\CurrentControlSet\Services\Winnat`.
2. Reboot the device.
