MikroTik L2TP/IPsec VPN Server Setup: A Full Guide (2026 Edition)
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.

MikroTik RouterOS is a versatile platform that allows users to configure a wide range of network solutions. Among its most popular features is the ability to function as a VPN server. Setting up a Layer 2 Tunneling Protocol (L2TP) server with IPsec encryption provides a secure, remote access solution for connecting back to a home or office network from anywhere in the world.
Before enabling the server, you must define the IP address range for remote clients and a profile to manage their connection parameters.
Before diving into the configuration, it is important to understand the technology. L2TP by itself does not provide encryption; it merely creates the tunnel. To secure the data, IPsec is used to encrypt the traffic. This combination is known as L2TP/IPsec. It is widely supported across all major operating systems (Windows, macOS, iOS, and Android) without the need for third-party software, making it an excellent choice for cross-platform compatibility.

L2TP alone does not provide encryption. For a secure "L2TP/IPsec" setup, you must configure the IPsec layer. : Define modern encryption standards. IP > IPsec > Profiles > + Hash Algorithms : sha256 Encryption Algorithms : aes-256 DH Group : modp2048 . IPsec Proposal : IP > IPsec > Proposals > + (or edit default ).
For multiple users, repeat this command with different names.
This is the most critical step for security. Since L2TP is unencrypted, IPsec creates the secure envelope around the tunnel. This link or copies made by others cannot be deleted
: If your MikroTik router or your Windows client is behind a carrier NAT router, Windows may fail to connect. To fix this, you must add a registry DWORD key named AssumeUDPEncapsulationContextOnSendRule with a value of 2 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent , then restart your PC. macOS Configuration
