Essentials Exam - Question 25


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.)

Show Answer
Correct Answer: A

If your Firebox has a single public IP address and you want to forward inbound traffic to internal hosts based on the destination port, the correct type of NAT to use is Static NAT. Static NAT, also known as port forwarding, allows you to map specific external ports to internal IP addresses and ports. This is essential for directing the inbound traffic to specific services hosted on different internal hosts, each distinguished by different ports. 1-to-1 NAT and Dynamic NAT do not provide the necessary port-specific forwarding functionality.

Why is this question still providing people with incorrect information while trying to prep for a cert they're about to pay $200 for? This is basic networking knowledge not to mention. I have passed this cert twice already and about to recert to make it the third time. Don't worry guys none of the exams I've seen had this question on it.

The answer is A. Static NAT for doing particular ports. If you had multiple public IPs and wanted to bring them through then you would use 1-1 NAT.
