how I can Block NetCut, mac changer from google play… please help me

In which environment?
It’s really hard if not impossible to make NetCut totally unusable.

If you’re talking about a HostSpot (which I presume), the easiest steps would be:

  • disbale client-to-client forwarding on the APSs
  • add all guest-facing interfaces with the same bridge horizon to your HotSpot bridge
  • hand out random /32 addresses and have one-to-one NAT do the rest.

That will definitely make it hard for the guys using Net Cut.

hand out random /32

how do you manage that?


I absolutely agree on all other points, I usually would add:

  • set proxy-arp to reply only on hotspot interface and set dhcp to add arp for leases

That’s a bit of an effort. Once.
Just create a pool per address and define a next-pool which then contains a totally different address. (like 1.2.3.4 ; 97.99.11.32 ; 120.254.244.13 etc…) From my experience, a couple of subscriber subnets from foreign ISPs are perfectly suited for gatherig random addresses that won’t conflict with internet addresses that might be needed.
Define the /32 mask in your dhcp-server network definition.
Create a real pool for 1to1 NAT.

Since 1to1 NAT needs full ARP, I didn’t suggest to set ARP to reply-only and dhcp-add (which is a good idea as well when not going for the approach described aboce).

That setup makes scanning of the network really really hard.

nice trick, indeed! surely worth a try.

I was guessing.. as ip are assigned by dhcp (so dhcp can add arp dynamically) probably the arp-reply method could work too. You say 1:1 nat needs full arp functionality but probably that is enough, did you test it?

Now we’re talking about it… I think you’re most likely right. I had the feature in mind that allows clients with different static IPs to access the network. But in this case, I’m now almost sure that it’ll work with static arp as well… No need to catch foreign static IPs. Good point!
