Stopping one device from abusing DHCP
Posted: Sun Mar 26, 2017 2:44 am
I have a mystery device somewhere on the network (not a clue who it is--I don't have access to everyone's hardware to start eliminating) that is generating an extreme number of DHCPREQUEST(br-lan)/DHCPACK(br-lan) items in the log.
Blocking in Restrictions has no effect on that traffic, so I thought that I'd add an iptables line to /etc/firewall.user to eventually flush out the device when someone comes to complain:
But it simply has no effect (also tried -j DROP at the end instead).
I tried restarting the firewall both ways (meaning including restart_firewall.sh).
Am I missing something?
