In order to configure a network website, I followed the ArchWiki nginx and BIND articles. But the BIND article seems to end when the website domain is available only from the host and not from other devices on the local network. So I have further consulted Installing a Local DNS Server Behind a Hardware Router.
To my understanding the router must be configured to use the host's BIND server, but it's unclear to me how that should be achieved correctly and as my attempts resulted in disconnections from the internet, I'd like to request assistance.
The server's local IP is '192.168.1.102', the chosen domain is 't.v' and relevant configuration files are similar to the ArchWiki.
The router has a page under 'Route' for 'DNS & default gateway configuration' which allows configuration of: 1. Domain name, 2. Primary DNS Server, 3. Secondary DNS Server, 4. Default Gateway, 5. DNS relay (enabled or disabled).
There is also a 'DHCP relay configuration' page for: 1. IP address, 2. DHCP relay (enabled or disabled)
Your precious time is much appreciated and thank you in advance.
