Mikrotik and OpenVPN

Hi Guys, There are some clients on my network that uses some software to change ip address like openVPN GUI, the software use to hit almost all the bandwidth, pls how can i block such from the network

Are you asking how you can block openvpn? You can block default ports easily, but if they are using different ports, then you can’t easily do this. If you are referring to setting speed limits, then you should just use simple queues per customer. Your question doesn’t make sense if it is not one of the two I mentioned.

I think simple queue will be much better…thanks for your reply
