Watchguard Network Security Practice Test

What type of NAT would you apply if your Firebox has a single public IP and you need to handle inbound traffic appropriately?

1. Static NAT

2. Dynamic NAT

3. 1-to-1 NAT

4. Policy-Based NAT

The correct answer is: Static NAT

To handle inbound traffic appropriately when your Firebox has a single public IP, applying Static NAT is the most suitable choice. Static NAT allows you to map a specific public IP address to a designated private IP address consistently. This means that any incoming traffic to the public IP will always be forwarded to the same internal device, ensuring reliable access to services hosted on that device, such as web servers or applications. This configuration is crucial for services that need to be accessed consistently from the outside world, as it provides predictability in routing incoming requests. For instance, if you run a web server on your network, Static NAT will ensure that every time someone tries to reach your server, the connection is directed correctly to the same private IP. Other types of NAT, such as Dynamic NAT or Policy-Based NAT, are less suited for this scenario. Dynamic NAT can assign a public IP from a pool for outgoing traffic but does not offer the static mapping needed for consistent inbound access. Policy-Based NAT might involve rules for traffic management based on specific conditions, which can introduce complexity without the straightforward requirement of having a fixed mapping for inbound requests. 1-to-1 NAT is often synonymous with Static NAT, but it may imply a broader context that is less precise when discussing the
