Mikrotik L2tp Server Setup Full 2021 Jun 2026

The profile defines the bridge between the VPN tunnel and your local network. Go to and click + . Name: l2tp-profile . Local Address: Your router’s LAN IP (e.g., 192.168.88.1 ). Remote Address: Select the vpn-pool created in Step 1. DNS Server: Add your preferred DNS (e.g., 8.8.8.8 ). Step 3: Enable the L2TP Server with IPsec

Before diving into the setup process, ensure you meet the following prerequisites:

/ip firewall filter add chain=forward src-address=192.168.100.0/24 action=accept comment="Allow VPN clients to forward" /ip firewall filter add chain=forward dst-address=192.168.100.0/24 action=accept comment="Allow responses back to VPN"

To begin the setup process, access your Mikrotik router using the Winbox configuration tool or the web-based interface.

Setting up an L2TP server on MikroTik RouterOS provides a secure method for remote users to access internal network resources . While L2TP itself does not provide encryption, combining it with ensures a high level of security compatible with built-in VPN clients on Windows, macOS, and mobile devices . 2. Technical Configuration Steps Phase I: Identity and Addressing

Without proper firewall rules, IPsec traffic will be blocked, or VPN clients won't reach your LAN.

Remote Address: vpn-pool (Select the pool created in Step 1). DNS Server: 8.8.8.8 (Or your local network DNS server). Click and OK . Step 3: Enable the L2TP Server Now, we activate the L2TP server functionality. Go to PPP > Interface . Click on L2TP Server . Check Enabled . Default Profile: l2tp-profile . Authentication: Check mschap2 (Secure). Important: Check Use IPsec .

If you need users to access the internet through the VPN (split tunneling off), you need a NAT rule. Go to > Firewall > NAT . Click + : Chain: srcnat Src. Address: 192.168.80.0/24 (Your VPN Pool subnet) Action: masquerade Step 7: Testing the Configuration Test from an external network (e.g., mobile hotspot). Windows Client Setup: VPN Provider: Windows (built-in). Connection Name: Any name. Server Name/Address: Your Public IP or DDNS. VPN Type: L2TP/IPsec with pre-shared key. Pre-shared Key: The key you set in Step 3. Username/Password: The credentials from Step 4. Summary Checklist Key Setting 1. Pool IP > Pool Range (e.g., 192.168.80.0/24 ) 2. Profile PPP > Profiles Select Pool + Local IP 3. Server PPP > L2TP Server Use IPsec: yes 4. Secrets PPP > Secrets Service: l2tp 5. Firewall IP > Firewall 500,1701,4500 UDP

You must allow L2TP/IPsec traffic through your MikroTik firewall . Go to > Firewall > Filter Rules . Add a new rule (Click + ): Chain: input Protocol: udp Dst. Port: 500,1701,4500 Action: accept Comment: Allow L2TP/IPsec Add another rule: Chain: input Protocol: ipsec-esp Action: accept Comment: Allow IPsec ESP Ensure these rules are at the top of your list. Step 6: Configure NAT Rule

The profile defines DNS servers, local IP, and pool settings.

Double-click your local bridge interface (usually named bridge or bridge-local ). Change the dropdown option from enabled to proxy-arp . Click OK . CLI Command: /interface bridge set [find name=bridge] arp=proxy-arp Use code with caution. 8. Verifying the Connections

(This will be the MikroTik's address within the VPN tunnel). Remote Address DNS Server or your local DNS. 3. Create VPN Users (Secrets) Each user needs a unique username and password. to add a user. StrongPassword123 l2tp-profile 4. Enable the L2TP Server

/ip firewall nat add chain=srcnat src-address=192.168.89.0/24 out-interface=ether1 action=masquerade comment="NAT VPN clients to internet"
