Almost forgot before going to bed but I feel bi-weekly is a good rhythm for this.
Let us know what you set up lately, what kind of problems you currently think about or are running into, what new device you added to your homelab or what interesting service or article you found.
Pihole 6 broke my DNS (dnsmasq), and since I had a fw rule in opnsense to only use pihole’s DNS, and deny public DNS access, it was an early rise for me :)
And that’s why you have either a backup for your DNS or know whats auto-updated ;)
As you mention opnsense:
What do you mean with fw rules to only use pihole dns?
This sounds partly like a DHCP config and partly like a deny (hardcoded) DNS requests and to please use what DHCP supplied (looking at you google/amazon)
I did have backups, it was an easy fix. I had a
pihole -up
on a crontab for years, probably not the best idea :)FW rule accept :53 from pihole only, deny :53 from all. I had some devices with hardcored DNS settings (8.8.8.8).
