Module 24: Introduction to Network Address Translation (NAT) in IP Tables
Lesson 1: Introduction to Network Address Translation (NAT) - Exploring the concept and significance of Network Address Translation - Overview of how NAT enhances network connectivity and security - Understanding the different types of NAT and their use cases
Lesson 2: NAT Types: Source NAT (SNAT) and Destination NAT (DNAT) - Understanding Source NAT (SNAT) and its purpose - How SNAT modifies source IP addresses for outbound traffic - Exploring Destination NAT (DNAT) and its role in modifying destination IP addresses
Lesson 3: IP Tables and NAT Tables - Overview of NAT tables in IP tables: `nat` and `mangle` - How NAT tables handle address translation and packet modification - The relationship between NAT and other IP tables components
Lesson 4: IP Masquerading and SNAT - Explaining IP masquerading as a form of SNAT - How IP masquerading dynamically selects a source IP for outgoing packets - Use cases for IP masquerading in NAT scenarios
Lesson 5: DNAT for Port Forwarding and Load Balancing - Understanding how DNAT is used for port forwarding and load balancing - Redirecting incoming packets to specific internal servers or services - The role of DNAT in enabling external access to internal resources
Activity: NAT Configuration Practice - Guided exercise: Configuring SNAT and DNAT rules for different scenarios - Demonstrating the effects of NAT on packet flow and address translation - Testing rules to ensure proper functioning of NAT configurations
Module 24 Assignment: NAT Strategy - Develop a strategy for implementing NAT in a network environment - Explain how the chosen NAT approach enhances network connectivity, security, and resource accessibility
Upon completing Module 24, learners will have a solid understanding of Network Address Translation (NAT) in IP tables. They will grasp the concepts of Source NAT (SNAT) and Destination NAT (DNAT), understand how NAT tables work, and be capable of configuring NAT rules to enhance network functionality and security.
