Configurar servidores DNS em um adaptador VPN no Windows 10 não tem efeito

3

Estou conectado a uma VPN, mas o Windows parece ignorar completamente o servidor DNS da VPN - todos os nomes resolvem o mesmo IP que quando não estão conectados à VPN, incluindo aqueles que devem resolver para um IP diferente.

Eu tentei configurar manualmente a métrica da interface, alterando a ordem do provedor ... Eu devo ter tentado cada aviso que achei que estava vagamente relacionado ao meu problema. Sem efeito.

Percebi que, quando executo $ nslookup <name> , a solicitação do DNS atinge o tempo limite:

$ nslookup <name>
DNS request timed out.
    timeout was 2 seconds.
Server:  UnKnown
Address:  10.131.4.133

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out

Eu configurei manualmente os servidores DNS no adaptador para 46.101.81.247 e 8.8.8.8 . O que eu não entendo é por que o nslookup mostra Address: 10.131.4.133 .

ipconfig confirma que 10.131.4.133 é o primeiro DNS nessa interface:

Mas o IPV4 mostra claramente apenas os dois servidores DNS corretos:

O que estou perdendo? Por que o Windows está ignorando o servidor DNS da VPN? E de onde vem o Address: 10.131.4.133 ?
