A zone is a grouping of interfaces. Zones also specify the services you can use to administer devices and authenticate users. When used with firewall rules, zones provide a convenient method of managing security and traffic for a group of interfaces.
|LAN||Groups interfaces with different network subnets so that you can manage them as a single entity. By default, traffic to and from this zone is blocked. To allow traffic between two LAN zone interfaces, you must add a LAN to LAN firewall rule.|
|DMZ||(De-militarized zone) Typically used for publicly accessible server networks such as web servers.|
|WAN||Used for all interfaces with a default gateway. Most likely used for internet access.|
|VPN||Automatically created interfaces used by IPsec or SSL VPN connections. When a VPN connection is created, the interface used by the connection is automatically added to this zone.|
|WiFi||Used for wireless internet services when a separate zone is configured. Bridge to AP LAN and Bridge to VLAN won't use a dedicated interface.|
