PortShield Groups

A PortShield interface is a virtual interface with a set of ports, including ports on Dell Networking X-Series, or extended switches assigned to it. PortShield architecture enables you to configure some or all of the LAN ports into separate security contexts, providing protection not only from the WAN and DMZ, but between devices inside your network as well. In effect, each context has its own wire-speed PortShield that enjoys the protection of a dedicated, deep packet inspection firewall. On the NETWORK | System > PortShield Groups page, you can manually group ports together that allow them to share a common network subnet as well as common zone settings.

Zones can always be applied to multiple interfaces in the NETWORK | System > Interfaces page, even without the use of PortShield groupings. These interfaces, however, do not share the same network subnet unless they are grouped using PortShield.

You can assign any combination of ports to a PortShield interface. All ports not assigned to a PortShield interface are assigned to the LAN interface.

TZ series firewalls support Dell Networking X-Series switches and the Dell Networking X-Series Solution, which expand the capability of the firewalls, especially for portshielding interfaces. See Configuring PortShield Interfaces for Dell Networking X-Series Switches.

NETWORK | System > PortShield Groups allows you to manage the assignments of ports to PortShield interfaces through:
