how to block shared connection of my client?
If they use a router you really can’t. You could limit the amount of connections but that is really a crapshoot
This was discussed here some time ago. I guess the thread is archived somewhere.
If you check the TTL on packets coming from the network you can delete any that have already traversed a router as they will show a lower value.

how can one check the TTL on packets coming from the network?
It can be done using Iptables…
But maybe some experts here can show us how you do that on RouterOS? Can it be done using RouterOS?
