How to monitor device traffic through a home router?

Question

WiFi

I welcome everyone. Tell me how to track visited urls from devices (smartphones, tablets, laptops) connected to a home router via wifi. There is a main PC connected via wire to the router, I would like to have access to it from it.

Router - ASUS RT-N12 VP B1

If possible, explain in more detail to make it clear or throw off the instructions, thanks.

Answer 1

No way. Your router is not capable of this.
In Mikrotik:
Tools->Packet Sniffer, a host is configured to which the necessary traffic will be mirrored. On the receiving host (on the computer), Wireshark is launched and listens on UDP port 37008, in the Wireshark filters, specify the ip.src of the client you are interested in, add an HTTP filter - voila, you see all the traffic.
For more details, google Mikrotik Packet Sniffer.
The second option is to make your computer a router: Linux as a transparent proxy, iptables is configured, you collect traffic on your computer, and the computer takes the Internet from the router. Of course, you will need to plug a WiFi whistle into the computer and organize an AP from it, but I think only the first option will suit you. The second is already too much for you, you have to rummage around in Linux.

Answer 2

You can use your PC as a gateway in your local network and collect traffic on it. You will need to manually specify a different gateway on the clients (the local address of your PC), instead of the one that came from the router via dhcp, and configure the routing on your PC accordingly.
But as you already wrote, you still won't be able to just see the full urls if HTTPS is used. To do this, you still have to arrange MitM and install your certificate on all clients.

Good afternoon, what is the purpose of collecting this data?
