Technical Support for Routers

GL.iNet GL-AR750S (NOR/NAND)
OpenWrt 19.07.8 r11364-ef56c85848 / LuCI openwrt-19.07 branch git-21.189.23240-7b931da

I am looking for a way to use the internal DHCP to update the internal DNS with the hostname.local.

Router is updated to the last available GL.iNet update which is 3.215.

You can try DHCP options 12 and 15.
