Hello, i read this:

Code:
# Ignore all ICMP ECHO and TIMESTAMP requests sent to it via broadcast/multicast
net.ipv4.icmp_echo_ignore_broadcasts = 1
and i checked my sysctl like this:

Code:
# sysctl -a | grep net.ipv4.icmp_echo
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.icmp_echo_ignore_all = 0
