What I don't understand is why I need to login to Centos via a putty session and type 'firewalld' from a command prompt in order for the Windows Remote Desktop session to connect. The version of firewalld is 0.4.4.4. Public zone is permanent with eth0 interface allowing http, https, ssh and port 3389 traffic.
Typical /var/log/firewalld log entries are:
