I can't seem to block ping requests to my server. I also followed the following post: Block ICMP timestamp & timestamp reply with firewalld
# firewall-cmd --zone=public --list-all
public
target: default
icmp-block-inversion: no
interfaces:
sources:
services: dhcpv6-client http ssh
ports:
protocols:
masquerade: no
forward-ports:
sourceports:
icmp-blocks: echo-reply timestamp-reply timestamp-request
rich rules:
# firewall-cmd --get-icmptypes
destination-unreachable echo-reply echo-request parameter-problem redirect router-advertisement router-solicitation source-quench time-exceeded timestamp-reply timestamp-request
And I also did a reload (firewall-cmd --reload), but was still able to ping my server. I'm not sure what else I have to do in order to block pings to my server.
