**Module 14: Rule Order and Its Importance in IP Tables**

**Lesson 1: Introduction to Rule Order**
- Understanding the concept of rule order in IP tables
- Overview of how rules are processed sequentially
- Importance of proper rule order for effective packet filtering

**Lesson 2: First Match Wins Principle**
- Explaining the "first match wins" principle
- How IP tables stops processing after a matching rule is found
- Implications of rule order on packet flow and filtering outcome

**Lesson 3: Rule Priority and Hierarchy**
- Understanding how rule numbers determine priority
- Higher rule numbers for higher priority rules
- Importance of arranging rules based on their intended impact

**Lesson 4: Rule Evaluation and Chain Flow**
- Exploring how packets traverse through chains and rules
- Interaction between different chains and the order in which they're evaluated
- Ensuring consistent chain flow and effective rule application

**Lesson 5: Impact on Security and Performance**
- How incorrect rule order can lead to unintended consequences
- The potential for conflicting or ambiguous rules
- Balancing security requirements with performance considerations

**Activity: Rule Order and Evaluation Simulation**
- Hands-on activity: Simulating packet flow through chains and rules
- Experimenting with different rule orders to observe their impact
- Analyzing the outcomes based on the "first match wins" principle

**Module 14 Assignment: Rule Order Strategy**
- Develop a rule order strategy for a given network scenario
- Explain how the chosen rule order aligns with security objectives and efficient packet processing

Upon completing Module 14, learners will have a solid understanding of the importance of rule order in IP tables. They will grasp the "first match wins" principle and understand how to strategically arrange rules to achieve desired security outcomes while maintaining efficient packet filtering and processing.
