Mikrotik L2tp Server Setup |link| Full -

You need WinBox or WebFig access with full administrative privileges. Example Network Topology

Click to add a rule for UDP Port 4500 (IPsec NAT-Traversal): Chain : input Protocol : udp Dst. Port : 4500 Action : accept Click OK . Click + to add a rule for UDP Port 1701 (L2TP traffic): Chain : input Protocol : udp Dst. Port : 1701 Action : accept Click OK .

If you need to optimize this setup for your specific infrastructure, let me know: Your (v6 or v7) Whether your router sits behind an ISP modem/NAT mikrotik l2tp server setup full

Ensure includes sha256 and Encr. Algorithms includes aes-256 cbc for compatibility with modern OS clients. 3. Enable L2TP Server

For the VPN to work, you must allow the specific L2TP and IPsec traffic through the MikroTik firewall. You need WinBox or WebFig access with full

: The router’s internal IP (e.g., 192.168.89.1 ). Remote Address : Select the vpn-pool created above. DNS Server : Enter your preferred DNS (e.g., 8.8.8.8 ). 2. Security: IPsec Configuration

RouterOS auto-creates proposals for PPP/IPsec L2TP but you should tighten them. Example for IKE1/main mode with strong algorithms: Click + to add a rule for UDP

By default, RouterOS uses weaker IPsec algorithms. For modern security, enforce strong ciphers.

/ppp secret add name=vpnuser1 password=StrongUserPassword123 service=l2tp profile=l2tp-vpn-profile Use code with caution. Step 4: Enable the L2TP Server with IPsec

L2TP/IPsec is actually two protocols. IPsec handles the encryption. Let's define a modern, secure proposal (AES-256 with SHA256).
