Module 25: Source NAT (SNAT) and Destination NAT (DNAT) in IP Tables
Lesson 1: Understanding Source NAT (SNAT) - Exploring the concept of Source NAT (SNAT) - Overview of how SNAT modifies source IP addresses in outgoing packets - Use cases for implementing SNAT in network scenarios
Lesson 2: SNAT Configuration - Configuring SNAT rules using IP tables - Specifying source IP addresses for translation - Addressing scenarios where SNAT is necessary for network communication
Lesson 3: Use Cases for SNAT - Applying SNAT for outbound internet traffic - Load balancing outgoing connections with SNAT - Implementing IP masquerading for dynamic source IP assignment
Lesson 4: Understanding Destination NAT (DNAT) - Exploring the concept of Destination NAT (DNAT) - How DNAT modifies destination IP addresses in incoming packets - Use cases for implementing DNAT to redirect traffic
Lesson 5: DNAT Configuration - Configuring DNAT rules using IP tables - Specifying destination IP addresses and ports for redirection - Addressing scenarios where DNAT is beneficial for resource accessibility
Activity: SNAT and DNAT Implementation - Guided exercise: Configuring SNAT and DNAT rules for different scenarios - Demonstrating the effects of SNAT and DNAT on packet flow and address translation - Testing rules to ensure proper functioning of SNAT and DNAT configurations
Module 25 Assignment: NAT Rule Strategy - Develop a strategy for implementing SNAT and DNAT in a given network environment - Explain how the chosen NAT approach enhances network connectivity, security, and resource accessibility
Upon completing Module 25, learners will have a solid understanding of Source NAT (SNAT) and Destination NAT (DNAT) in IP tables. They will be proficient in configuring SNAT and DNAT rules to modify source and destination IP addresses, respectively, and will be capable of using these techniques to enhance network functionality and achieve specific networking goals.
