I have 5009 router.
What kind of configuration I should have if I would like to configure one port of my router as test port. So if I connect an equipment to that port, I will get data into the logfile where I can see if that equipment is trying to take connections to some strange addresses?
Is it enough to just block everything and look what will be in the log?

Maybe this will be useful https://youtu.be/9UvFG9nUN0Q
