What is Firewalld?
Who is using it?
Firewalld is used in the following Linux distributions as the default firewall management tool:
- RHEL 7, CentOS 7
- Fedora 18 and newer
- Available for several other distributions
The most distinctive feature of Firewalld compared to IPTables is that it uses zones. Zone rules apply. Each zone can use different configurations. You can change all the rules that you apply by changing these zones.
Firewall-cmd is the most basic command we will use.
