I am trying to access devices on a secondary router (172.20.14.0 range) in a lan network from a device on the main router with (192.168.1.0 range).The secondary router is connected to the main router and assigned an ip address of 192.168.1.21 and then the secondary router assigns the devices connected to it ip addresses in the 172.20.14.0 range. How can I access the devices on the secondary router just by entering their address in a web browser?
