Hi!
Let’s say there is three APs A,B,C and main router D, running routeros 2.9.51
All three access points are connecting to main router (D) in wds slave mode.
What i need to do, so my clients don’t see each other in LAN because they sometime share files,and consume lot’s of network bandwitdh.
I tried on cards where omni antennas are connected to set default forwarding=no, but i don’t see some good results.
Did i miss something?
probably yes 
Thanks!
Best regards!
