Estoy conectado a una VPN pero Windows parece ignorar por completo el servidor DNS de la VPN: todos los nombres se resuelven a la misma IP que cuando no están conectados a la VPN, incluidos los que deberían resolverse a una IP diferente.
Intenté configurar manualmente la métrica de la interfaz, cambiar el orden del proveedor ... Debo haber probado todos los consejos que encontré que estaban vagamente relacionados con mi problema. Sin efecto.
Noté que cuando ejecuto $ nslookup <name>la solicitud de DNS agota el tiempo de espera:
$ 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.

*** Request to UnKnown timed-out
He configurado manualmente los servidores DNS en el adaptador para 46.101.81.247y 8.8.8.8. Lo que no entiendo es por qué aparece nslookup Address: 10.131.4.133.
ipconfig confirma que 10.131.4.133es el primer DNS en esa interfaz:

Pero IPV4 muestra claramente solo los dos servidores DNS correctos:

¿Qué me estoy perdiendo? ¿Por qué Windows ignora el servidor DNS de la VPN? ¿Y de dónde Address: 10.131.4.133viene el?
