How To Block Neighbor Discovery On MikroTik
The main challenge of users with Neighbor Discovery is that when they have a Mikrotik on the internet, it means that everyone is able to access it through Neighbor Discovery. As you guess it seems a little scary because your Mac address and Mikrotik information could be easily stolen by hackers.
What is the solution?
It is clear that you need to disable this protocol to prevent your Mikrotik from being found through Winbox and the Neighbor Discovery section to be able to connect it only by entering your IP address.
Ways To Block Neighbor Discovery On Mikrotik
There are two ways to block Neighbor Discovery on your Mikrotik.
1) Block Neighbor Discovery via WinBox
2) Blocking Neighbor Discovery via Mikrotik Terminal
Let’s see how you should use these solutions and how do they function.
Block Neighbor Discovery Via WinBox
In this part, you will learn the first way of blocking Neighbor Discovery on Mikrotik. Let’s review the required below steps to learn it completely.
1) First, you should connect to your mikrocontroller to block MNDP via Winbox.
