Filtering PPPoE Requests Based on MAC Address in Mikrotik

In this tutorial, we will discuss how to filter PPPoE requests based on MAC address in Mikrotik. This is a common scenario where you need to restrict access to your network by allowing only specific devices with their MAC addresses.

Usually, PPPoE dialer is configured in user WiFi ROUTER. However, if you are running a network or ISP/ WISP and using Mikrotik as a PPPoE server, you may have encountered the problem of many users configuring their wifi router at home to share internet between mobile/laptop and other devices, which is common these days.

To overcome this issue, we can use MAC address filtering in Mikrotik. This allows us to restrict access to our network by only allowing devices with specific MAC addresses.

In Mikrotik, you can create a filter rule that checks the source MAC address of incoming PPPoE requests and only allows connections from specified MAC addresses. To do this, follow these steps:

1. Go to IP > Firewall > Mangle

2. Click on the '+' button to add a new mangle rule

3. Set the chain to 'postroutes'

4. Set the protocol to 'pppoe'

5. Set the action to 'change-mac-src'

6. In the MAC address field, enter the desired MAC address(es) that you want to allow or block

For example, if you want to allow only devices with MAC addresses starting with 00:11:22, you can enter `00:11:22/XX` in the MAC address field.

7. Click on the 'Apply' button to save the changes

By implementing this filter rule, we can restrict access to our network by only allowing devices with specific MAC addresses. This is a simple yet effective way to control who has access to your network.

In this tutorial, we have seen how to filter PPPoE requests based on MAC address in Mikrotik. We hope this helps you secure your network and prevent unauthorized access.
