Within the span of about an hour today, i received 9 WAN disconnected alerts (Health check DNS test failed).
I was using default health check settings of 5 seconds, but using Cloudfare as my DNS resolver on WAN. I increased the health check interval to 60 seconds, thinking perhaps Cloudfare is ignoring and rate limiting my IP.
No issues for about 30 minutex or so… anyone else experience this issue?
is it best practice to leave the WAN DNS resolver settings to automatic and rely on the ISP provided DNS servers, and only change the DHCP DNS servers?
