Explanation
When configuring a NAT rule, the administrator must provide a name for the rule, the source zone from which traffic originates, and the destination zone where the traffic is headed. These are fundamental parameters for the firewall to identify and apply NAT correctly.
Common mistakes.
- C. While a destination interface can be part of a NAT rule for specific scenarios (like interface-based NAT), it is not a universally minimum required field for all NAT rule types.
- D. A destination address is often used in NAT rules but is not strictly required for all NAT rule types (e.g., some dynamic IP and port NAT configurations might not need a specific destination address defined in the rule itself).
