This important zone is used for controlling traffic that is sourced from or directed to the router itself. The zones we create are placed into zone pairs.
What is a zone-based policy firewall?
A Zone-based firewall is an advanced method of the stateful firewall. In a stateful firewall, a stateful database is maintained in which source IP address, destination IP address, source port number, destination port number is recorded.
What are zone pairs?
A zone pair can be defined as a pairing of two zones in a direction. A firewall traffic policy is then applied to a zone pair. Firewall traffic policy is applied unidirectional between zones. Two zone pairs are required for traffic on both directions.
