TP-Link Switch as Network Tap
I have a question similar to this post from 2020:
https://community.tp-link.com/en/business/forum/topic/185164
I want to capture the traffic between my router and ISP modem by connecting the modem to port 1, the router to port 2, and my PC to port 5 where Wireshark is capturing the specific packets I want to observe. Miroring is simple.
What is not simple is preventing packets from my PC from going out ports 1 and 2.
The post from 2020 suggested creating an 802.1Q VLAN (10) for the mirror port, and...... "Check if can isolate the mirror port." and the discussion ends.
I don't mind spending $25 on Amazon to get an SG-105E, but would be rather annoyed if after doing so, it won't work.
Although the link between modem and router is gigabit, the actual internet capacity is only 200mbs, so the concern about being able to handle 1000m/Full does not seem to a factor.
Was hoping someone can advise if this will work... and specifically how to set it up.
Thanks
