My ISP's switch port is being put down due to error in dynamic arp inspection.
I investigated and the reason is that when Kerio Control internet interface loses connection to its gateway, it start sending ARP requests like "Who has", so when the gateway comes back again, it's instantly disconected again due to massive ARP traffic sent to ISP's switch.

I need to either make Kerio Control stop asking my ISP about Google's MAC address absurdly or at least limit frequency of such requests.

If devs can't fix such behaviour, please integrate ebtables or arptables at least.
