Every month or so all my devices lose internet and the only way to connect them all back is to disconnect them from the DNS server that Pihole is running.
I set my Pihole to have a static IP but for some reason after around a month or maybe longer, it just fails. This has happened 4 times over the last while and the only fix is to essentially uninstall everything on my Pihole, disable it, and then reconfigure it from scratch again.
I’m not sure what’s going on so any help would be appreciated.
I have up on Pihole a long time ago because of constant issues. Went with self hosted AdGuard and haven’t had a single issue since.
Do you use ethernet to usb adapter?
Are you assigning the static address on your pi, or are you assigning a static address on the router?
This. I’ve always done dynamic IPs on my devices and set static IPs for them on my router. Never had an issue.
This is the way. Although, to clarify, you should assign static IPs on your DHCP server, which for most SOHO networks, that’s going to be your router.
If you assign statics on your hosts, your DHCP server will assign them the preferred address if available, but if it’s already assigned then the DHCP server is going to give your device the middle finger and assign them whatever the fuck it wants.
Not sure if I’m misunderstanding you, but the router/DHCP server doesn’t assign an IP at all to a host that you’ve assigned statically. Any given host can be statically assigned or use DHCP, not both.
The real problem with statically assigning IPs to hosts, is that your DHCP server won’t know that and could give a new device the same IP address as your statically assigned host, causing an IP conflict, if you statically assigned the host with an IP that’s inside the DHCP scope.
What you have to do is only assign static IPs that are outside the DHCP scope, or set all hosts to use DHCP and then use reservations in your DHCP server to make sure they get the same one each time.
Yeah it is? There’s a reason your dns confutation has a backup IP address.
I run pihole on a proxmox cluster (lxc containers), 2 separate IPs and I setup keepalived and made the virtual IP the primary dns ip that my dhcp server hands out, pihole1 is the master and pihole2 secondary. I use gravity sync to keep both piholes in sync. Works very well and I can reboot one at a time without losing dns at all. Techno tim on YouTube has a guide on how to setup keepalived on 2 pihole servers that helped me set it up.
You should probably also sync them. I use orbital sync for this. https://github.com/mattwebbio/orbital-sync
That’s a good idea that I hadn’t considered. I’ll see if I can get Pihole running on an old android phone I have lying around.
Edit: I now have PiHole running on an old Pixel 3a and have decommissioned my PiHole docker container on my home server.
I have a google router and It allows me to enter 2 DNS servers incase the first DNS Server doesnt work.
