Explain what Firewall blocks in PfSense (traffic from nginx)?

Question

Information Security

Little by little I began to pick PfSense, set it up there, tuned it up there. Got to the firewall logs. There's a flurry of blocked data from 92.242.43.211:257 to my WAN (and the ports that get hit vary from about 20000 to 50000). I went to the source address, there is a page with an inscription that some nginx is installed and working successfully. Explain to the junior where they are afraid and is it worth it?

Answer 1

He has a built-in pfBlocker, most likely it works.

Answer 2

Someone has hacked into someone's web host and is brute-forcing your network through it. Standard (now) situation. Set up blocking attacking nodes based on such logs, and you will have (temporary) happiness.
