firewalld commands

Need the following firewalld commands (CentOS7/RHEL7) Allow connections on Port Allow connection from IP (any open port) Deny connection from IP (any open port) Stop/Start/Restart the firewall Allow connections on port from IP deny rest You should give several examples of each command, and they should work with a single or multiple IP as well as IP ranges in cidr format, and also IPv4 and IPv6 examples. Also all rules should work together, IE, I can allow access to one IP server wide, and allow access to another IP for only one port. And I should be able to: add 1 IP, add a 2nd IP, add a 3rd IP, remove the 2nd IP online, and the 1st and 3rd IP still have access. Bonus if you can make a small script to do this, with an allow and deny file.
