It is necessary to track (listen) all traffic through the router (all home devices via WiFi), will a network bridge help?

Question

network hardware

Greetings!
https://zyxel.ru/kb/2814/ - this site presents an option (item 3) of wiretapping router traffic using a network bridge. Everything seems quite possible, but when creating a network bridge on a PC (the router is connected via WAN to a network card - an adapter to USB in the PC system unit, the provider's cable is connected to the built-in network card of the same PC), there is no connection to the Internet.
The second minus that came up was the passage of data through NAT, which means the uselessness of the method, although it seems that the method is quite working, I'm just missing something.
Is it possible to use this method to catch with Wireshark all packets going to the router (dumps) from devices connected to the network via a WiFi network?
(OS Windows 8)
How else would it be possible to catch all packets and see the traffic? Not enough knowledge for a completely independent mastering =(.

Answer 1

if you mean using a PC under Windows, then two network cards, one of which is "Internet", the second is plugged into the router, WAN connectors. combine network adapters into a
ps bridge but you will not know who is sending traffic, all packets will be from the router (since there is NAT)

Answer 2

Such an occupation, now most of the traffic is HTTPS or, in principle , Secure .
