These rules disables NetBios traffic between clients, so they cant see each other shares that are made in windows (shared disks, printers)
You maybe want to block p2p traffic too.

if they are ethernet clients (eg they connect to a hub or switch), then you can’t disable windows file sharing - they will connect over the switch, directly. and not throufh the router.

if they are wireless clients, simply set default-forwarding=no and that’s it

I had big trouble…
my network…can give access with other ip register in one network, if they know the web-proxy port. Clients can throught without bandwith limitting…
even i set ip in mangle they can force without bandwith limiting
How could that be. I want the register Ip can access my IP router? can u give the solution?
Note : I used Web-proxy… with port 8080
i already set all network 192.168.0.0/24 will go throuh web-proxy
now if client used other IP, they can access throuh router with out bandwith limit. Please support me.
