Description:

This course provides an introduction to the architecture and implementation of Virtual Private Networks (VPNs). You will learn how to build secure tunnels across public networks, master the mechanics of IPsec and SSL/TLS, and gain hands-on experience configuring and troubleshooting production-grade VPN servers.

Key Highlights:

• Tunneling Mastery: Understanding encapsulation for Site-to-Site and Remote Access.
• IPsec Deep Dive: Mastering IKE phases and protocol modes (AH vs. ESP).
• Modern Protocols: Implementing SSL/TLS VPNs using OpenVPN.
• Practical Troubleshooting: Solving real-world server and client configuration errors.

What you will learn:

• Build Secure Tunnels Master encapsulation to bridge the "Public Network" gap. Practice selecting between Site-to-Site (IPsec) and Remote Access (SSL) based on business connectivity needs.
• Master IPsec & SSL Mechanics Explore Layer 3 security and TLS handshakes. Learn why UDP is preferred over TCP to prevent the "TCP Meltdown" effect in modern tunnels.
• Configure Production Servers Gain hands-on experience setting up OpenVPN. Manage PKI and certificates, and act as a "Config Doctor" to repair broken server files and routing tables.
• Deploy & Audit Clients Learn to deploy client profiles and authenticate users. Analyze failed connection logs as a "Log Detective" to identify and resolve common TLS and gateway errors.
