Worrying UDP trying to connect

I think screen says it all. It’s not my IP but my provider is same as him. Different locations. What the hell? Is he trying to hack me or what?

Right after I have closed port for hamachi and then hamachi Windows Operating System block appeared.

I just looked up Hamachi and it allows you to connect to other computers on the web like you are on a LAN.

Are you sure the other IP address is not part of the network you are on with Hamachi? If it is not somebody from the network then it is most likely a port scan. That’s what you have a firewall for of course. To put up a wall against these kind of things.

Just thinking out loud. I am not sure whether a port scan is enough reason to file a abuse report with the sender’s ISP.
