Description
Port Shield architecture enables you to configure some or all 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 Port Shield that enjoys the protection of a dedicated, deep packet inspection firewall.
NOTE: Zones can always be applied to multiple interfaces in the Network |Interfaces page, even without the use of Port Shield groupings. However, these interfaces will not share the same network subnet unless they are grouped using Port Shield.
