Objectives by Chapter

1. ISP/WISP Network Segmentation

   • Learn how to divide a WISP network into multiple subnets to efficiently handle IP addressing.
   • Understand the problems associated with using a single network segment and how segmentation can solve them.
   • Identify current network needs to determine the number of subnets and devices per subnet required.
   • Use subnetting and VLSM tools to assign appropriate subnet sizes and improve IP address space utilization.

2. Static Routing Configuration

   • Understand how to configure static routing to ensure effective communication between all internal networks and provide Internet access.
   • Learn the importance of having a detailed network diagram and how to use tools to create it.
   • Gain knowledge of how to define manual routes in routing tables, specifying the destination address and gateway.

3. Troubleshooting NAT over NAT

   • Identify and resolve the double NAT issue on a network with multiple devices performing NAT.
   • Configure static or dynamic routing to enable effective communication between internal subnets without the need for multiple instances of NAT.
   • Learn how to disable NAT on intermediate devices, keeping it only on the edge router and client end devices.

At the end of this Tutorial

Upon completion of this tutorial, the student will be able to:

• Design and efficiently segment an ISP/WISP network to improve its performance and security.
• Implement Static and dynamic routing to manage network traffic and improve redundancy.
• Solve double NAT issues, optimizing NAT configuration for efficient and secure Internet access.
• Use subnetting and VLSM tools for more efficient use of IP address space.
• Keep record properly configure the network configuration and established routes to facilitate future maintenance and troubleshooting.
• Identify and resolve connectivity and performance issues resulting from poor NAT configuration.
• Improve network management and monitoring by eliminating unnecessary NAT configurations on intermediate devices.
• Purchase practical skills in network administration that allow applying effective solutions to common network infrastructure problems.
