The Lab

Complete VPN troubleshooting decision trees for IPsec, WireGuard, and L2TP. Step-by-step diagnostics for connectivity issues, handshake failures, authentication errors, and routing problems. Includes common error messages and solutions.

Complete remote user VPN configurations using WireGuard and L2TP/IPsec. Includes server setup, client configurations for Windows/Mac/iOS/Android, user management, access controls, and troubleshooting. Choose WireGuard for speed or L2TP for built-in OS support.

Simple 5-minute WireGuard VPN setup between two MikroTik routers. Modern encryption, faster than IPsec, easier troubleshooting. Includes interface creation, peer configuration, routing, firewall rules, and support for hub-and-spoke topologies.

Complete copy-paste ready IPsec VPN configuration for connecting two sites. Includes peer configuration, proposal settings, policy setup, firewall rules, NAT exceptions, and troubleshooting. Best for MikroTik-to-non-MikroTik or when IPsec is required.

Deploy working VPN in 30 minutes with copy-paste templates. Four scenarios: Site-to-Site WireGuard (20 min), IPsec (30 min), Remote User WireGuard (25 min), and L2TP/IPsec (30 min). Includes verification checklists and common adjustments for quick implementation.

Systematic VPN troubleshooting with diagnostic commands for IPsec, WireGuard, and L2TP. Solve six common problems: tunnel establishment failures, handshake issues, connectivity problems, random disconnects, client connection failures, and slow performance with decision trees.

Provide secure remote access with WireGuard (fast, requires client) or L2TP/IPsec (built-in OS support). Create IP pools, configure authentication, set up clients for Windows/Mac/iOS/Android, manage user access, and control network permissions with firewall rules.

Modern alternative to IPsec using public/private key pairs. Create WireGuard interfaces, generate and exchange keys, configure peers with allowed addresses, and set up routing. Faster setup (5-8 min vs 15-20 for IPsec) with fewer settings and simpler troubleshooting.

Connect two offices with IPsec VPN. Step-by-step configuration covering two-phase negotiation, peer setup, pre-shared keys, proposals, and policies. Includes required firewall rules, NAT considerations, testing procedures, and troubleshooting decision trees for common issues.

Compare VPN protocols: WireGuard (modern, fast, simple), IPsec (industry standard, interoperable), L2TP/IPsec (built-in OS support), and why to avoid PPTP. Includes decision matrix for choosing the right protocol based on your scenario and performance needs.
