Solution

  • Depending on your router model (I assume you have a standard home ISP router), you should be able to mirror your Router's traffic into a particular LAN port on the device. This will act as a sort of "LAN-TAP", and will mirror all traffic flowing through the Router to that port.

    Here is an article explaining it.

    However, you should ask yourself whether or not this is particularly necessary.

    Most home routers are realisticaly, just a switch that acts as a PAT Router for your ISP. You can't do any funky routing on your own LAN with them, so this router is just sitting back and forwarding packets that are travelling over the LAN. This means that due to your home router broadcasting packets from devices on the network, the packets are naturally going to be hitting your network adapter too, which will be visible on Wireshark.

    However, if you are wanting to be viewing packets that are being routed by your Router to Outside the network, go ahead and enable port mirroring.
