Here is the setup: A US Robotics USR-9108 router is connected to an ADSL modem via ethernet cable. The modem, upon connecting with the ISP, provides a gateway address of 192.168.1.1
to the router. End-users including me connect to the internet through the router via WiFi and are assigned the IP 192.168.1.2
...192.168.1.255
.
When disconnected from the modem, I can access the control panel via 192.168.3.1
but once the ethernet cable is plugged in I cannot access the above-mentioned IP; connecting to 192.168.1.1
opens up the modem's control panel. Any possible way to access the router control panel while it is connected to the internet?
Edit: is this called "transparent routing"?
