Mikrotik L2tp Server Setup Full ((full))

Prerequisites:

Step 8: Optional but Recommended – DNS

Step 7: The Firewall Rules (Critical!)

# Check active L2TP interfaces /interface l2tp-server server print

• A MikroTik router (RB series, CCR, or CHR) running RouterOS v7+ (v6 is similar but verify paths).
• A public WAN IP (dynamic DNS is fine).
• A network range for VPN clients (e.g., 192.168.100.0/24).
• WinBox or SSH access.

• use-ipsec=required forces IPsec encryption (L2TP alone is insecure).
• ipsec-secret: Pre-shared key – clients will need this. Change YourStrongPreSharedKey immediately.

1. [ ] PPP Profile setup (Local IP, Remote IP Pool, DNS).
2. [ ] IPsec Peer configuration (with NAT-Traversal enabled).
3. [ ] Strong Proposals (AES-256, SHA-256, MODP-2048).
4. [ ] Firewall Filter Rules (Input chain).
5. [ ] MTU adjustment (fixes web browsing issues).
