How to prevent a VPN connection from pushing its DNS?

Question

Domain Name System

Windows 10 Home. The essence of the problem. There is a vpn connection for corporate needs. But when connected, the DNS server of the VPN connection starts to be used. How can I stop him from doing this. And I still don’t understand why, when the system makes a name request from the DNS server and does not receive it, it does not try to ask the server that I have on the network connection? Shouldn't she question them one by one?

Answer 1

You most likely do not have a problem with DNS, but the default route is specified in the VPN settings, and accordingly, by default, all traffic goes through the tunnel.
Remove the default route, add the necessary routes to the corporate network.

Answer 2

How to prevent a VPN connection from pushing its DNS?

VPN pushes nothing, so there is nothing to prohibit.
The system uses the DNS server specified in the network connection settings.
By itself, it does not appear there, either you registered it there with your hands, or it was issued by the DHCP server.
See what you prescribe, or see what the DHCP server gives out. That's all.

And I also do not understand why, when the system makes a request for a name from the DNS server and does not receive it,

The system uses exclusively the DNS server specified in the network connection settings, and no other.

Answer 3

What VPN client? Not Cisco AnyConnect by chance?

Answer 4

IMHO, it's not good to use "all" resources - connected to a corporate vpn - and it's right that he gives you his dns-server, use corporate resources, everything else is disconnected. Otherwise, your corporate resources will easily be inaccessible (when using the same Google DNS)
