Logs to investigate connection to IP address

[gorocket1981]

Hello,

I have an external IP address and I would like to find which device(s) on my network tried to connect to this IP address.
I am looking in the GUI and console and I don't find the correct log to get this information. I have an Asus AC-3100.

I would hope to have logs where I could search for the IP and get the information.
How should I proceed to to this investigation? Where should I look in GUI or console to know which devices tried to connect to this IP address?


Thanks a lot for your help.

All devices on your local network behind NAT connect to Internet via your external WAN IP address.
