Mikrotik RouterOS

The following guide was created using a Mikrotik network with the following components:

• Router: Mikrotik RouterBoard 450G
• Firmware: 3.22
• WebFig: v6.23

Requirements

You need to have a Mikrotik RouterBoard with Internet access already configured.

You can reset your RouterBoard and connect the cable with Internet access at the ethernet gateway port (ether1-gateway).

By default, the RouterBoard is configured with automatic address acquisition, so it will get the IP and Gateway from your Internet cable connection and will set up a DHCP Client also.

Interfaces

By default, the RouterBoard 450G comes with 5 ports and the following interfaces:

• ether1-gateway
• ether2-master-local
• ether3-slave-local
• ether4-slave-local
• ether5-slave-local

In this guide, we'll create a new interface (bridge-hotspot) and associate one of the slaves interface to the bridge.

Ethernet

Go to Interfaces and edit one of the interfaces (e.g. ether4-slave-local). Change the following options:

• Name: ether4
• Master Port: none

Bridge

Go to Bridge and click in "Add New". Set the following options:

• Name: bridge-hotspot

Now you need to associate the Ethernet interface to the bridge.

Go to Bridge > Ports tab and click in "Add New". Set the following options:

• Interface: ether4
• Bridge: bridge-hotspot

Radius

Go to Radius and click in "Add New". Set the following options:

• Enabled: checked
• Service: Hotspot
• Address: the RADIUS server IP according to your environment/region
• Secret: the provided RADIUS client secret
• Authentication Port: 1812
• Accounting Port: 1813
