Change settings for ping requests

You can allow your PC to be seen by other PC users on your network by allowing ICMP ping requests, which are communications from one PC that test if another PC is reachable over a network. You should allow ICMP ping requests if you want other PCs to be able to communicate with your PC, or if you are trying to troubleshoot a networking issue.

Preventing ICMP ping requests makes it harder to detect your PC online, and reduces the risk of a hacking attempt.
