3 NAT Books That Separate Experts from Amateurs

VPNs and NAT for Cisco Networks offers a detailed dive into tunneling, DMVPN, VPNs, and NAT as outlined by Stuart Fordham, a CCIE Certified Network Engineer. Drawing from his extensive expertise, Fordham guides you through building networks from the ground up, beginning with GRE tunnels and advancing to phase 3 DMVPN solutions for both IPv4 and IPv6. You gain hands-on understanding of routing protocols like EIGRP, OSPF, and BGP, alongside quality of service implementation. The book also explores IPv6 transition mechanisms such as 6over4 and 6to4, making it a solid pick if you're aiming to master Cisco networking with a focus on secure, scalable architectures.

What if everything you knew about managing Linux firewalls and NAT was wrong? Gregor N. Purdy challenges conventional wisdom by diving deep into Linux's Netfilter system through the lens of iptables, a command-line interface renowned for its complexity and power. You’ll learn how to handle stateful filtering, manage large rule sets effectively, and even monitor network traffic accounting—skills crucial for securing and optimizing Linux network environments. The book’s chapters carefully break down challenging syntax and provide a practical reference for tasks like opening ports or blocking suspicious ICMP traffic. If you’re tasked with Linux network security or NAT, this concise guide puts essential commands and strategies within easy reach.

When Waldemar Quevedo first discovered NATS while working with CloudFoundry at Rakuten, he recognized its potential as a lightweight messaging system ideal for cloud native and microservices architectures. This book walks you through the fundamentals of NATS, from its protocol and communication styles to configuring servers and operating them in production. You'll find practical examples, including how to implement advanced client features like failure detection and tracing, helping you transition from REST APIs to messaging-based designs. If you're developing microservices and want a solid grasp of NATS to improve service discovery, load balancing, and low latency communication, this book matches those needs well.
