Client avoids Changing Static IP Address

how to prevent the client to change the static IP Address which we provide?. probably one of the questions that you've come to mind. This setting is usually required for school networks. Often try to change-change client ip address, still greet their intentions know that does not get an IP address in the limit. So with this setting if client ip address that does not change according to what we give, they can not use the internet connection. Let us exploit mikrotik firewall functions.

You make bandwidth management with setting like this:

Client 1: IP 172.22.0.23, the limit of 64kbps download 256kbps upload limit
Client 2: IP 172.22.0.34, limit 1mbps download, 256kbps upload limit



Well, the client 1 nyoba2 ya change-change ip address until he met using the client IP 2. He can get automatic client limit 2 limit is greater. Jump up and down a client for over speeding 4x internet so much.

Here's one technique that avoids this, by using firewall mikrotik.

/ip firewall filter
chain=forward action=drop src-address=!172.22.0.23
src-mac-address=00:75:34:65:8Z:5D

chain=forward action=drop src-address=!172.22.0.34
src-mac-address=00:34:62:15:5A:9E

Explanation of the above script:

Mac address one of your client (00:75:34:65:8 Z: 5D) with a chain = forward (past the mikrotik router / access to the internet) when using IP address will be 172.22.0.23 THAN drop dead or contrived.

We make this with the intention to maintain the comfort of our client.
