CSF Firewall not Allowing Incoming PING
« on: January 18, 2021, 06:51:40 AM »
Although the settings in /etc/csf/csf.conf are as recommended to allow incoming PING, is not working as it should be.

# Allow incoming PING. Disabling PING will likely break external uptime
# monitoring
ICMP_IN = "1"

Results:

Any idea what else should be enable?

Resolved this issue in AWS EC2, by adding a Firewall Rule for All ICMP - IPv4 to the Security Group
