OpenVPN: Not using Local DNS server

[normanos]

Generally, same problem which was in this topic:
https://forum.opnsense.org/index.php?topic=3598.0

Have In LAN network local DNS server.

When connecting with VPN to local network by IP address opens web page, but if i putting related domain name, its not working.
Attached picture.

but websites, like opnsense.org opening. Its bypassing local DNS server and going straight to 1.1.1.1

  Sorry, i don.t know how more detailed explain.

Maybe someone sorted it out in 4 years from original post? Its closed as it was sorted.
