arp-spoofing detection

Does anyone know a script to detect ARP spoofing.
That by which a client is connected to the router board.

Just a suggestion: is management-frame protection deployable on your scenario?

Hello Pukkita, What exactly do you want to say?
My English is very poor
Thanks for your quick reply

I mean, how does the client connect to your network? By using a mikrotik CPE device connected to a mikrotik AP device?

No, with computer or laptop.

I would love to know the answer for the mikrotik ap/cpe scenario.

Regarding a Mikrotik AP/CPE scenario, management frame protection adds an additional layer of security preventing MAC spoofing see http://wiki.mikrotik.com/wiki/Manual:Interface/Wireless#Management_frame_protection

plisken, is this a hotspot scenario? a (W)ISP?

No, its not a hotspot but public ap.

So to control access you just use MAC ↔ IP binding?

Maybe this post can give you some ideas: http://forum.mikrotik.com/t/32-subnet-mask-to-prevent-arp-spoofing/26921/1
