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.

This essay outlines the step-by-step process of configuring an L2TP/IPsec server on a MikroTik router, covering authentication methods, IP addressing, firewall adjustments, and troubleshooting. Comprehensive Guide to Setting Up an L2TP Server

Step 2: Configure the L2TP Server

Enable the L2TP server. By default, it uses port 1701. We'll tell it to use our new pool and allow MPLS and encryption. Windows 10/11 (Built-in client)

/interface l2tp-server server set enabled=yes default-profile=default-encryption use-ipsec=required max-mtu=1400 max-mru=1400

Pro Tip: Setting use-ipsec=required forces clients to negotiate IPsec. No insecure L2TP-only connections allowed.

4.1 Allow IPsec and L2TP ports

Add input chain rules to accept VPN-related packets:

/ip firewall filter add chain=input protocol=udp dst-port=500,1701,4500 action=accept comment="Allow L2TP/IPsec"
/ip firewall filter add chain=input protocol=ipsec-esp action=accept comment="Allow ESP (IPsec)"

On iOS/Android:

Similar steps using the built-in L2TP/IPsec VPN client.

Windows 10/11 (Built-in client)

  1. Create new VPN connection → L2TP/IPsec with pre-shared key.
  2. Use the same YourStrongPreSharedKey.
  3. Disable "CHAP" and "MS-CHAP v1", enable "MS-CHAP v2".
  4. Set authentication to "Allow unencrypted password" (only if MPPE fails – normally leave off).
