Design and Configure DMZ Networks Using Cisco Routers in Packet Tracer – A Practical Security Lab Course
Are you ready to take your networking skills to the next level? Want to build secure network architectures just like the pros—without being held back by outdated tools? Then this course is for you.
What you’ll learn
- Understand what a DMZ (Demilitarized Zone) is and why it’s critical in network security design..
- Design and build a functional DMZ network in Cisco Packet Tracer..
- Implement NAT and Port Forwarding to expose public services safely from the DMZ..
- Use OSPF and static routing to connect internal, DMZ, and external networks logically and securely..
- Apply Access Control Lists (ACLs) to tightly control traffic between internal, DMZ, and external networks..
- Understand the role of edge routers, DMZ routers/firewalls, and internal LAN segmentation..
- Control outbound and inbound traffic to protect internal resources and prevent unauthorized access..
- Use real-world best practices to simulate enterprise-grade security setups—even in Packet Tracer!.

Requirements
Are you ready to take your networking skills to the next level? Want to build secure network architectures just like the pros—without being held back by outdated tools? Then this course is for you.
In this hands-on course, you’ll learn how to design and configure a fully functional DMZ (Demilitarized Zone) Network using Cisco routers in Packet Tracer.
You’ll start with the basics—what a DMZ is, why it’s important, and where it’s used. Then, you’ll dive into the practical skills: configuring an Edge Router, setting up the DMZ Firewall Router, connecting your internal LAN, and adding public-facing servers like web and mail servers. You’ll also configure NAT, port forwarding, OSPF routing, and powerful ACLs to manage and secure traffic between each zone.
What makes this course different? It’s designed to be 100% hands-on, realistic, and engaging. You’re not just watching commands—you’re building, configuring, and troubleshooting like a true network engineer.
By the end of this course, you’ll have:
- A fully working DMZ topology in Packet Tracer
- A deep understanding of how to control traffic between internal, DMZ, and external networks
- Practical experience with NAT, ACLs, and routing protocols in a secure design
- The confidence to design and explain DMZ networks in interviews or the workplace
Whether you’re studying for certifications, building a lab, or just passionate about network security, this course gives you the skills to level up your networking career.
