firewalld list is here. It's been pretty quiet lately.

I didn't do anything special to allow ICMP. I notice that one of your links 
suggests making the drop zone the default zone. That may be the source of 
the problem.

Try posting the output of "firewall-cmd --list-all-zones" and/or 
"iptables-save" to a pastebin for readers to inspect.
