This guide provides a comprehensive, step-by-step tutorial on setting up an on MikroTik RouterOS (v6 and v7). L2TP (Layer 2 Tunneling Protocol) combined with IPsec (Internet Protocol Security) is a secure, widely compatible method for remote access, allowing mobile devices and remote offices to connect securely to your MikroTik network.

: Enter a strong, pre-shared key (e.g., MySuperSecretKey ). Clients will need this key. Authentication : Check mschap2 . Click Apply and OK . Step 5: Create a VPN User (Secrets) Create credentials for a user to connect to the VPN. Go to PPP -> Secrets . Click + (Add) . Name : remoteuser Password : UserPassword123! Service : l2tp . Profile : l2tp-profile . Click Apply and OK . Step 6: Firewall Configuration (Crucial)

In the world of remote access, security and reliability are paramount. While PPTP is now considered obsolete due to known vulnerabilities, L2TP (Layer 2 Tunneling Protocol) combined with IPsec provides a robust, secure, and widely compatible VPN solution. Almost every operating system—Windows, macOS, iOS, Android, and Linux—supports L2TP/IPsec natively, requiring no third-party client software.

Click to add a rule for the IPsec-esp protocol (Encapsulating Security Payload): Chain : input Protocol : ipsec-esp Action : accept Click OK .

If your router is behind another NAT device (e.g., an ISP modem in router mode), you must forward UDP ports 500, 1701, and 4500 to your MikroTik’s LAN IP. For best results, put your ISP modem in bridge mode.

With the IP addressing sorted, the next step is to enable the L2TP service.

/ip firewall filter add action=accept chain=input dst-port=1701,500,4500 protocol=udp comment="Allow L2TP/IPsec" add action=accept chain=input protocol=ipsec-esp comment="Allow IPsec ESP" Use code with caution. Copied to clipboard 6. Verification and NAT (Optional)
