I use Advanced Tomato v128 and enabled permanently the OpenVPN client. Interface-Type is set to "TUN" and protocol to "UDP".
I can of course easily check over some ip-information webpage that my traffic is effectivly routed over the VPN-server.
Anyway, I don't know, if the DNS - queries go over the VPN. Or does the router still send the DNS-queries to the modem? In this case, of course, the DNS-queries go from my modem to the ISP. This would be a privacy concern. Or does it send the DNS-queries to the VPN?
So to be sure, I would like to find a way to do some kind of a traceroute for the DNS queries to see, where they go through and what DNS-server is actually queried (PC and router get the DNS server address over DHCP for their default configuration).
How can this be verified?
