Lesson 8: NAT Considerations When Managing Your Security Policy
Firewall Management 201: Lesson 8
A business owner makes a simple change request to allow traffic to a new application. You now need to figure out the right firewall rules to change. This should be pretty simple… but what if you’re using NAT (Network Address Translation) in your environment? In this lesson, Professor Wool explains some key principles of NATing and why it’s critical to understand your NAT policy in order to identify the right paths for network traffic, which firewalls rules really need to be modified, and how to write your security policy correctly.
