I have a device on my LAN that has Google's DNS hard-coded into it. Meaning that even when I configure the device to use other DNS servers, like Cloudflare, it reverts back to 8.8.8.8 and 8.8.4.4 and cannot be changed.
Is the only way around this to create a DNAT rule that changes the destination to a different DNS server?
Is this correct:
For traffic from: network definition (IP address of the device)
Using service: DNS
Going to: External (WAN) Network / External IPv4
---------------------------------------------------------------
Change the destination to: Network Definition (which would be my internal DNS server, or I.P. address of the internal DNS server.)
And the service to: DNS
Would this cause issues with DNSSEC? Should I perhaps change the destination to my default gateway and use the DNS forwarders (my DNS server) setting of the UTM?
