WatchGuard Network Security Essentials — Question 6

If your Firebox has a single public IP address, and you want to forward inbound traffic to internal hosts based on the destination port, which type of NAT should you use? (Select one.)

Answer options

• A. Static NAT
• B. 1-to-1 NAT
• C. Dynamic NAT

Correct answer: A

Explanation

Static NAT is the correct choice because it allows you to map a single public IP address to multiple internal IP addresses based on the destination port, enabling specific traffic forwarding. In contrast, 1-to-1 NAT is used for a direct mapping of one public IP to one internal IP, and Dynamic NAT typically assigns IPs from a pool, which does not facilitate port-based forwarding.
