Description

current /usr/local/sbin/ovpn-linkup script doesn't use OpenVPN-pushed DNS servers,
you need to catch them in the logs and add them manually.

Status -> System Logs -> OpenVPN:

PUSH: Received control message: 'PUSH_REPLY,dhcp-option DNS 10.3.3.1,redirect-gateway def1,sndbuf 524288,rcvbuf 524288,explicit-exit-notify,comp-lzo no,route-gateway 10.3.3.1,topology subnet,ping 10,ping-restart 60,ifconfig 10.3.3.1 255.255.0.0,peer-id 0,cipher AES-256-GCM'
