01Give it the address of Warda
Once the certificate of Network → DNS services is there, the page shows the DoH address of your box (https://xxxxxxxxxx.warda-dns.net/dns-query):
- Firefox: Settings → Privacy & Security → DNS over HTTPS → Max Protection → Choose provider → Custom, then the address.
- Chrome, Edge, Brave: Settings → Privacy and security → Security → Use secure DNS → Custom (Edge: Enter custom provider), then the same address.
02Or turn it off
Without a custom provider, turn the secure DNS of the browser off: it then asks the DNS of the system, Warda. Firefox asks a test name before turning its DoH on by itself; Warda answers it so that Firefox keeps the DNS of the network.
03What stays
Only the browser is covered: the other applications use the DNS of the network. The known DoH services are blocked for the children and teenagers; for a device that asks another resolver directly, only a rule of the router closes the way.
