Yes, it is completely possible to use a tunnel broker for IPv6 and assign VLANs within a MikroTik device.

Both features are supported by RouterOS, the operating system that powers MikroTik devices.

We explain how each of these technologies can be implemented in MikroTik and how they can work together.

Using Tunnel Broker in IPv6 with MikroTik

A tunnel broker is a service that facilitates the transition from IPv4 to IPv6 by providing IPv6 connectivity to networks that only have native IPv4 access. This is especially useful in situations where your ISP does not provide direct support for IPv6.

Tunnel Broker configuration in MikroTik:

1. Choose a Tunnel Broker: First, you should choose a tunnel broker provider that supports IPv6, such as Hurricane Electric.
2. Create a Tunnel: Register and create an IPv6 tunnel with the chosen broker. They will provide you with the necessary details such as the tunnel server address and the IPv6 addresses assigned to your tunnel.
3. Configure the Tunnel in RouterOS:
   • Access your MikroTik RouterOS.
   • Configure the tunnel interface with the parameters provided by your tunnel broker (you can do this under the “Interfaces” menu).
   • Add the necessary routes to direct IPv6 traffic through your new tunnel interface.

Assign VLANs in MikroTik

VLANs are used to segment a physical network into multiple logical networks. This can improve network management, security, and reduce the size of broadcast domains.

VLAN configuration in RouterOS:

1. Configure the Physical Interface: Choose the physical interface on which you want to create the VLAN.
2. Create the VLAN:
   • Go to “Interfaces” and then “VLAN”.
   • Creates a new VLAN, assigns a VLAN ID, and associates the VLAN with the corresponding physical interface.
3. Configure IP Addresses: Assigns IPv6 addresses to each VLAN as needed.

Integration of Tunnel Broker and VLANs in MikroTik

You can combine these configurations so that the VLANs in your local MikroTik network use IPv6 through a tunnel provided by a tunnel broker.

Each VLAN can have its own IPv6 network segment, and traffic from each VLAN can be routed through the IPv6 tunnel for access to the broader network.

Considerations:

• Security: Be sure to implement appropriate security measures, especially when exposing your local network to the Internet via IPv6.
• Training: Monitor network performance to ensure that tunnel and VLAN settings are not negatively affecting speed or quality of service.

This configuration provides a great way to take advantage of the benefits of IPv6 while maintaining the flexibility and control provided by VLANs in a MikroTik environment.
