**Module 36: Creating a Basic Firewall Configuration with IP Tables**

**Lesson 1: Introduction to Basic Firewall Configuration**
- Exploring the fundamentals of creating a basic firewall configuration
- Overview of the components and considerations for a simple firewall setup
- Understanding the importance of balancing security and network functionality

**Lesson 2: Defining Objectives and Requirements**
- Identifying the security objectives and requirements for the firewall
- Determining which services need to be accessible and which should be restricted
- Addressing scenarios where different security levels are required

**Lesson 3: Designing Rule Sets**
- Creating rule sets based on the defined security objectives
- Using the `filter` table to implement filtering and access control rules
- Applying rules to the `INPUT`, `OUTPUT`, and `FORWARD` chains as needed

**Lesson 4: Implementing Basic NAT and Port Forwarding**
- Configuring Source NAT (SNAT) or Destination NAT (DNAT) for network address translation
- Setting up port forwarding rules to enable external access to internal resources
- Addressing scenarios where NAT and port forwarding are necessary

**Lesson 5: Enabling Logging and Auditing**
- Configuring basic logging and auditing rules for security monitoring
- Using the `LOG` target to generate log messages for specific events
- Understanding how logging enhances visibility into network activity

**Activity: Creating a Basic Firewall Configuration**
- Guided exercise: Creating a simple firewall configuration using IP tables
- Designing rule sets, implementing basic NAT and port forwarding, and enabling logging
- Testing the configuration to ensure network functionality and security objectives are met

**Module 36 Assignment: Basic Firewall Strategy**
- Develop a strategy for creating a basic firewall configuration based on predefined security objectives
- Explain how the chosen approach balances security and network functionality, while ensuring proper access controls and visibility

Upon completing Module 36, learners will have a practical understanding of creating a basic firewall configuration using IP tables. They will be proficient in designing rule sets, implementing access controls, setting up basic NAT and port forwarding, enabling logging, and achieving predefined security objectives. This knowledge will enable them to establish a foundational level of network security while maintaining essential network functionality.
