I'm trying to implement the advice from one of my previous posts (https://forum.opnsense.org/index.php?topic=50925.0), but how to do the below?
QuoteIn Dnsmasq / Domains, create a global override and enter the IP address of the ISP's DNS server.
I tried entering nothing,
. or
~., or
*. Only * worked.
QuoteA value is required.
QuoteLabels must be 1–63 characters, start with a letter or digit, and may contain only letters, digits, '-' or '_'.
Is specifying * as the domain the right way to add custom upstream DNS to dnsmasq?
