Linux router ARP storming ISP
by mik256 from LinuxQuestions.org on (#4VF40)
The problem: my linux router (Debian based) losts connection to the gateway and it starts sending ARP like for "who has 8.8.8.8?" in such frequency, that the gateway gets shut down due to packet inspection my ISP has configured on their port. Of course I am on different subnet than Google, so why it makes such attempts if the route is not accessible instead of just waiting? How to prevent this or at least limit? I can't use stuff like arptables or ebtables and tc seems a bit too difficult. Thanks!
