My understanding of this setting is that it would generate rules for the firewall rule sets that allow or block pings. This doesn't seem to be the case. You still need to open up the firewall manually for the ICMP echo requests. Pinging works then. However, when you put the all-ping to disabled, ping requests stop working. So probably this is a sysctl setting. On IRC, dmbaturin suggested moving the setting perhaps to system options ip.
