I have zerotier bridged on my openwrt router. Windows clients outside of my home are using the DNS of my home pi-hole. I would like them to not be able to automatically find the pi-hole, and instead require me to assign the ip of the pi-hole for queries. Windows apparently tries to fetch DNS from every ethernet adapter and picks whichever responds the quickest.
- router: 192.168.196.1/23
- DHCP: 192.168.196.100-254
- pi-hole: 192.168.196.91
- Managed routes: 192.168.196.0/23
- auto assign: 192.168.197.100-254
All of my devices outside of the home network are assigned addresses in the 192.168.197 block.
