I use IPFire 2.25 update 142 on a stand alone PC to front end all of my Linux and Windows PCs. I have setup DNS over TLS on IPFire without any problems. It works just fine !!!
My Linux & Windows PC’s run Perfect-Privacy-VPN which has its on secure DNS servers in many countries. Their web site also offers various tests to check IP & DNS leaks.
I have set Mozilla Firefox to NOT use Firefox DNS over TLS as I do not wish to use Google or Cloudfare as they track and profit from DNS queries.
So is there a way on IPFire to log which DNS IP address are being sent out on the RED interface ? Looking at the “Connections” list on the WUI tool leaves me confused.
I know that the VPN’s DNS Servers are being used as when I select only one of their many servers, and search for “www.bloomberg.com”, I get a TCPIP address for that servers location (ie US, France, Netherlands, etc).
Which makes me wonder when does the IPFire DNS over TLS get used ?
Clearly whenever the VPN DNS server is not active.
So it sure would be nice to have a log on IPFire that tracks only DNS server IP addresses on the RED interface. Is this possible ?
