How to connect 2 cameras with fixed IP addresses (they can be also dinamic) to be seen and controled from outside - over Internet, and from inside over wlan. One is connected to ether1 (100.100.100.100) and the other on wlan1 (200.200.200.200) ports on Rb 411U. There is no xDSL line, so access to the internet is possible only through the GSM modem connected via a USB port and it works fine. How to connect to the no-ip dynamic DNS account ( or similar). I search and tried a lot and I not found a good solution yet, so I ask for the solution and help.
