I couldn't figure out why I could ping from my lan to my dmz and vice versa.
No firewall rules to allow ping.
Everything unchecked against ping under ICMP firewall rules.
Today, I deselected "Allow traceroute through gateway" & "Gateway forwards traceroute"
Boom! No more ping! Hope that helps somebody who might go through this. I was scratching my head for ages with it and thought I was going mad!
