Hi, It is my first time using wireshark, I have an ESP32 which perform connections to an specific IP outside of my LAN. Is it possible with wireshark to know which one is that target IP?

I'm using this example as an initial approach but I would like to check the security of my IP cameras to see if they are streaming only to an specific IP instead of an external server.

Thank you

"my current mikrotik router"
"the esp connects via wlan"

Does the esp connect to the mikrotik? Does the router support Packet Sniffer?

Either setup port mirroring in your switch so you can see all traffic through your router or to and from your ESP32 for example.

But for a full list of options you should read

I'm not sure that my current mikrotik router allows me to setup a port mirroring from the ESP, based on wiki I don't see a clear way of how to set a monitor mode in the wlan card(I'm currently on windows) to monitor the wifi traffic, the esp connects via wlan too

Mikrotik seem to offer some form of packet capture:

I'm trying to figure it out with the packet sniffer, thank you for the suggestion
