Adguard home works only if I manually set the device's IP address to my router's IP. Otherwise the device isnt given any DNS server IP. Does anyone know what's going on?
If you dont specify the option then its not set. Follow the guide and it will work.
The guide sets both the gateway and DNS servers in case you deploy the dns on a different device. This way clients know their ip address, the gateway and dns servers.
Can you provide this information from the guide/WIki? Do you have a link?
This seems inaccurate...unless you're referring to the AdGuard home package...?
OpenWrt assigns gateway and DNS (the OpenWrt) by default. Are you saying that some Adguard home guide explains that gateway and DNS will no longer be assigned when running?
