When VPN is established, and the DNS relay proxy is running on Windows 10, the DNS resolution does not work for queries made to the IPv6 DNS server.
- DNS resolution does not work.
- Windows 10. - DNS Relay Proxy Service is running. - IPV6 DNS server specified in Network Access Settings
There are 2 workarounds: 1. Add the following key: HKLM\SOFTWARE\Policies\Microsoft\Windows NT\DnsClient -Set DWORD "EnableMultiHomedRouteConflicts" to 0 (zero). This workaround restores Windows DNS client behavior to pre-Windows 10 where this is not an issue. 2. Specify IPv4 DNS server as well in the Network Access configuration.
