Should I block outgoing and incoming ICMP?


I use Debian as a host. Should I block incoming and outgoing ICMP connection or just incoming?

Any basic firewall like ufw will block incoming ICMP. As for outgoing you don’t need to worry since all you need to do is stop pinging sites from the host.

Outgoing, no reason.
