Kali/OpenVPN/DNS

Steps

Set up OpenVPN as described on the Kali/OpenVPN page.

Next, we will tell anyone on the VPN network we just created to use the gateway/host machine as the DNS server. This ensures DNS queries are passed through the gateway/host machine.

On the gateway machine, edit /etc/openvpn/server/server.conf

Make the gateway machine the DNS resolver by adding the line

push "dhcp-option DNS <IP-ADDR-OF-TUN0-INTERFACE>"

For me,

push "dhcp-option DNS 10.8.0.1"

Also comment out any other push "dhcp-option DNS lines.

Now restart the OpenVPN server on the gateway machine:

sudo systemctl restart openvpn
