Ahh, I must have read it inside out...
You'll need to create two packet filters:
1.
Name: "DMZ Ping In"
Filter Type: ICMP ping query
Local Computer: "These computers (on the perimeter network)"
(enter your DMZ subnet here)
Remote Computer: <your choice, but I prefer to IP-limit this>
2.
Name: "DMZ Ping Out"
Filter Type: ICMP all outbound
Local Computer: "These computers (on the perimeter network)"
(enter your DMZ subnet here)
Remote Computer: <your choice, but I prefer to IP-limit this>
