[QUOTE="valvaris, post: 902394, member: 38787"] Ohhh... now I get it.... so the Router can not be edited! DNS is set at the Windows PC Client. Then the issues starts: - Windows 10 by default tries to go over IPv6 (That has been disabled.) = OK - Windows 10 by default has mDNS enabled for Local Network hence LAN - Port 5353 - LeakPotential - Application Controlled DNS over HTTPS / TLS is a Proxy on Windows Client that can.. Depends on config not work coz of Certificates. - Windows 10 UWP Apps can have a Static DNS Entries...- Use Software Firewall to Block it! - If a Switch is used in the Network for Example a "Cisco SG250" they can break DNS and Leak.... Now to the LeakTests: - Take it with a grain of salt! -> Not all LeakTest are equal and are very Browser dependent! - Some Browsers use alternative DNS Address Settings others can forward the traffic to other DNS Servers if things are in use like DoH or DoT. Known DNS Ports: DNS Port 53 TCP/UDP - DoH (DNS over HTTPS) DNS over TLS Port 853 TCP/UDP - DoH (DNS over HTTPS) mDNS Port 5353 UDP Known Browsers with build in DNS Services: Firefox - DoH - Options/Preferences > General > Network Settings. Edge Chromium - DoH - at edge://settings/privacy on feature versions current canary build. Chromium = I don't know... Sincerely Val. [/QUOTE]
