I previously as a working pi-hole system, with an all-in-one TP-LInk 8960 modem/router/wifi (192.168.1.1) and NAS (192.168.1.10) wth dockerized pi-hole (192.168.1.20)
But my DSL is so slow that I decide to replace it with 4G.
Now I struggled to have pi-hole works again.
- 4G alcatel hh40 router (192.168.0.1, DHCP: off, WIFI: off)
- Zyxel router (WAN: 192.168.0.2, WAN gateway: 192.168.0.1, WAN DNS: 22.214.171.124, LAN: 192.168.1.1, DHCP: on, WIFI: on)
- NAS (192.168.1.10) with dockerized pi-hole (192.168.1.20)
With this setup, I can navigate to the web, but pi-hole is not working.
As soon as I configure Zyxel WAN DNS to 192.168.1.20, nothing works anymore.
I guess pi-hole should be in the WAN domain (192.168.0.*)
Do you have any idea how to set-up?
Maybe it’s impossible, and the solution is to install pi-hole on a dedicated rpi/odroid and plug it directly on the 4G router. (192.168.0.XX)
