Pre-Flight Check
- These instructions are intended for finding (viewing) active zones in Firewalld on CentOS 7 via the command line.
- I’ll be working from a Liquid Web Core Managed CentOS 7 server, and I’ll be logged in as root.
All network interfaces exist within a zone. They can be located in the default zone or split into other zones. Zones enhance an administrator’s capability to define trusts and restrict network traffic.
Note: On installation and without any configuration, the default zone for firewalld is set to the public zone.
