Virtual private networks / Some clarification on DNS via VPN
« on: May 07, 2024, 10:18:01 pm »
I have configured one of my appliance ports to use ProtonVPN and I followed the official instructions including this: https://docs.opnsense.org/manual/how-tos/wireguard-client-proton.html#protonvpn-dns-leaks
I have only a smart TV connected to that port (LAN2), with a static IP address of 192.168.10.16 (for ProtonVPN is then 10.2.0.2).
Using the embedded browser, I've checked any potential DNS leaks browsing to www.dnsleaktest.com website, and no leaks occur (it only detects the ProtonVPN server).
In ISC DHCPv4 for LAN2, I have included the DNS server as the Proton one - 10.2.0.1
Now, if I look at the Firewall -> Live View of both the above IP addresses + port=53, I see the smart tv querying not just the ProtonVPN IP address (10.2.0.1) but also Google DNS servers, how is that possible?
Any suggestions would be much appreciated.
