Hi,

Can this be done from FreePBX? Searches have resulted primarily of the below solutions but none work for me.

Asterisk 13.12.1

echo “1” > /proc/sys/net/ipv4/icmp_echo_ignore_all

echo “0” > /proc/sys/net/ipv4/icmp_echo_ignore_all

You can add following line to /etc/sysctl.conf file:

vi /etc/sysctl.conf

Append following line:
net.ipv4.icmp_echo_ignore_all = 1
