I just installed a fresh new server with CSF

Soon I find out that my ping keeps dropping. The server was smoothly running, SSH is smooth, Website are loading fine, except I cannot ping my server. I disable SELINUX completely and it still doesn't help.

When I disable CSF, my server ping are responding back!

So I remove CSF installation and reinstall CSF, the same problem appear

How can I solve this issue?

My kernel is 2.6.18-92.1.6.el5PAE running on latest version of cPanel on CentOS 5.1

Edit the config from WHM -
Find the module in the bottom left ConfigServer FireWall
Firewall Configuration.

Search for PING in your list of options, you'll come across

(1 means yay, 0 means nay)
# Allow incoming PING
ICMP_IN = 1

when i change ICMP_IN_RATE = 0 from 1/s, the ping works.

but is it safe?
