SonicOS 7 Match Objects

Predefined Zones

The predefined zones on your firewall depend on the device.

The predefined security zones on the SonicWall Security Appliance are not modifiable:

This zone Has this function
DMZ Normally used for publicly accessible servers and can consist of one to four interfaces, depending on your network design.
LAN Cn consist of multiple interfaces, depending on your network design. Even though each interface has a different network subnet attached to it, when grouped together, they can be managed as a single entity.
MGMT Used for appliance management and includes only the MGMT interface. Interfaces in other zones can also be enabled for SonicOS management, but the MGMT zone/interface provides the added security of a separate zone just for management.
MULTICAST Provides support for IP multicasting, which is a method for sending IN packets from a single source simultaneously to multiple hosts.
SSLVPN Used for secure remote access using the SonicWall NetExtender client.
VPN A virtual zone used for simplifying secure, remote connectivity.
WLAN

Provides support to SonicWall SonicPoints and SonicWaves. When assigned to the Opt port, it enforces SonicPoint Enforcement, automatically dropping all packets received from non-SonicPoint devices. The WLAN zone supports:

  • Discovery Protocol (SDP) to automatically poll for and identify attached SonicPoints and SonicWaves
  • SonicWall Simple Provisioning Protocol to configure SonicPoints and SonicWaves using profiles
  • Wireless and guest service configurations
WAN Can consist of multiple interfaces. If you are using the Security Appliance’s WAN failover capability, you need to add the second Internet interface to the WAN zone.

Even though you can group interfaces together into one security zone, this does not preclude you from addressing a single interface within the zone.
