Why can’t I ping my Synology NAS when I enable my FireWall

I’ve been locking down the firewall on my Synology NAS to only allow certain ports from specific IP subnets. After enable the firewal, ping stopped working from external command prompt. I still wanted to be able to ping the Synology from anywhere. I couldn’t work out how to configure the Synology firewall to let through Internet Control Message Protocol (ICMP). Here is the answer.
You have to go to: Control Panel -> Security -> Firewall -> Create:
Under ports select Custom and then under protocol select ICMP.
Press OK a few time and then Save the firewall settings. You should then be able to ping the NAS without any problems.
Happy Pinging
