Some users on my network using
netcut to prevent other users from accessing the internet
[ ISP's router: public IP ] - [ gateway: public IP eth1 - network eth0 (NAT) ] - [ switch and access point ] - [ clients ]
all other computer connects to eth0 as gateway, using Wifi or LAN..
how to prevent one client poison other clients arp cache, the gateway is using Linux?
arpon seems has no effect..
or is there any product (switches and access point) that has ARP spoofing protection?
