DNS randomly stops working
Basic setup - clients have their DNS set to the netgate router LAN / Gateway.
Clients will randomly stop working and cant access anything on the internet. setting a client to 220.127.116.11 DNS manually and voila it works. a reboot of the netgate works and it will work for a while and then out of no where clients using the netgate as DNS will stop working again. Its getting annoying now and wondering if anyone has experienced this?
I have been experiencing this as well every few days since upgrading an SG-5100 to 21.02 (and now p1). Unbound silently dies and stops logging, and pfSense shows unbound as not running. This never happened previously with 2.4.5p1 and prior. I just setup some probes and monitors yesterday to see if I can learn more at next occurrence.
