I have 2 standard network routers (both DHCP-enabled), one behind the other as below:
WAN --> Router A (192.168.1.1) --> Router B (192.168.100.1)
Router B's WAN is connected to one of Router A's LAN ports. I can access the internet on all devices without problems.
If I have a computer connected to Router B (let's 192.168.100.7), how can I have it access Router A's admin webpage, or any computer on the Router A LAN network?
