The Complete Guide to MikroTik L2TP/IPsec Server Setup

Introduction

Layer 2 Tunneling Protocol (L2TP) combined with IPsec (Internet Protocol Security) is one of the most common VPN solutions for remote access. While not as modern as WireGuard or SSTP, L2TP/IPsec offers a good balance of security, native support on virtually all operating systems (Windows, macOS, iOS, Android, Linux), and reasonable performance.

6.1 Allow IPsec and L2TP Input

  1. Check the MikroTik router's logs for any L2TP-related errors.
  2. Verify that the L2TP client and server settings are correct.
  3. Optimize the L2TP settings for better performance (e.g. adjust the encryption method, increase the L2TP idle timeout).

Step 7: Optional – Split Tunneling vs. Full Tunneling

By default, all internet traffic from the VPN client will go through your MikroTik (full tunneling). This increases latency but provides security. The Complete Guide to MikroTik L2TP/IPsec Server Setup

Performance Considerations

L2TP/IPsec is CPU-intensive due to encryption and encapsulation. On low-end MikroTik (hEX, RB750), expect: Check the MikroTik router's logs for any L2TP-related errors
