Create a new firewall zone named "office" with IP range 192.168.65.0/24,
firewall-cmd --new-zone=office --add-source=192.168.65.0/24 firewall-cmd --reload
firewall-cmd --new-zone=office --add-source=192.168.65.0/24 --permanent firewall-cmd --reload
firewall-cmd --add-new-zone=office --add-source=192.168.65.0/24 --permanent firewall-cmd --reload
Firewall zones can be created for many reasons. For example: your office has a specific range of IP. Your boss has asked to open everything for your office IP range. What would you do? There are several ways you can achieve that. But the most efficient way would be to create a new zone with office IP range and allow everything in it. Since you might need to add other rules for office, to best to keep it all in a zone instead of adding hundreds of rules in the public_zone. Example screenshot - http://prntscr.com/ge9mxg
