Analyzing Network Traffic with Fritz!Box ======================================== Owner of Fritz!Box routers can capture traffic accessing the URL http:///html/capture.html that is typically http://192.168.2.1/html/capture.html Inside the page you can dump traffic in pcap format for later analysis. If instead you want to monitor traffic in realtime with ntopng you can do that easily using the script ntopng/tools/fritzdump.sh As you can see it will connect to the Fritz!Box (modify the script to adapt it in case you have different setups) and send ntopng via the stdout all the incoming traffic. Thanks to this solution you can use ntopng to monitor in realtime all the traffic that is flowing inside your Fritz!Box router
