How to Route L2TP IPv6 Link Local to Internet on Mikrotik
Routing L2TP IPv6 link local traffic to the internet can be a complex task, especially when dealing with Mikrotik routers. However, with the right configuration and understanding of the underlying protocols, it’s entirely feasible. In this article, I’ll guide you through the process step by step, ensuring you have a clear understanding of each aspect involved.
Understanding L2TP and IPv6
L2TP (Layer 2 Tunneling Protocol) is a VPN protocol that allows for secure communication over the internet. It’s often used in conjunction with IPsec for encryption. IPv6, on the other hand, is the latest version of the Internet Protocol, designed to replace IPv4 due to its limited address space.
When you’re setting up L2TP IPv6 link local routing, you need to ensure that your Mikrotik router is configured to handle both protocols effectively.
Configuring the Mikrotik Router
Before you begin, make sure your Mikrotik router is running the latest firmware. This ensures that all features and security updates are available.
Step 1: Enable IPv6
Log in to your Mikrotik router and navigate to the IP > Addresses section. Click the plus button to add a new address. Set the following parameters:
Parameter | Value |
---|---|
Address | 2001:db8:0:0:0:0:0:1/64 |
Network | 2001:db8:0:0:0:0:0:0/64 |
Interface | WAN |
Replace “WAN” with the appropriate interface name if you’re using a different interface.
Step 2: Configure L2TP Server
Go to VPN > L2TP > Server and click the plus button to add a new server. Set the following parameters:
Parameter | Value |
---|---|
Interface | WAN |
IPv6 Address | 2001:db8:0:0:0:0:0:2 |
IPv6 Network | 2001:db8:0:0:0:0:0:0/64 |
IPv6 DNS | 2001:4860:4860::8888 |
Replace “WAN” with the appropriate interface name if you’re using a different interface.
Step 3: Configure L2TP Client
Go to VPN > L2TP > Clients and click the plus button to add a new client. Set the following parameters:
Parameter | Value |
---|---|
Interface | WAN |
IPv6 Address | 2001:db8:0:0:0:0:0:3 |
IPv6 Network | 2001:db8:0:0:0:0:0:0/64 |
IPv6 DNS | 2001:4860:4860::8888 |
Replace “WAN” with the appropriate interface name if you’re using a different interface.
