Join Sean Colins for an in-depth discussion in this video Understand Firewalld zones, part of Linux: Firewalls and SELinux.
- [Instructor] Zones are the main concept…in Firewalld that you're going to need to understand…in order to properly configure the service.…The Fedora Project defines…a Firewalld zone as follows.…A network zone defines the level of trust…for network connections.…This is a one to many relation…which means that a connection can only be part of one zone.…But a zone can be used for many network connections.…Okay, what the heck does that mean?…Well, basically, it's this.…We have the idea of zones all over…the computer and technology world.…
In DNS for example, we have zones that define a domain,…and contain host records, MX records, PTRs and more.…That's just an example.…A Firewalld zone isn't much different than that.…It's a collection of connection types basically.…Let's take a look at what the firewall supports here…at the command line.…We're going to get a list…of all supported zones from Firewalld.…We're going to type firewall-cmd…and then another space and then --get-zones…Just to be clear, that's firewall-cmd --get-zones…
