I routinely see questions related to firewall on forums which cannot be answered without seeing the actual configuration. Unfortunately firewalld does not seem to offer any simple way to list it.
I use the back-end's commands to dump the "real" firewall. Like "iptables-save" or "iptables -L -v -n". It's a bit like debugging a C++ program by looking at the generated assembly language. I've done that when chasing a compiler optimizer bug back in the 90s. (Compilers tend to be much better now.)
