Re: blocking unwanted traffic from hitting gateway

For what it's worth, here are some things I did to cut down on broadcast traffic until I figure out the other pieces --Putting router in between subscribers and gateway (handles thousands of ARP requests every minute much better than Linux) --DCHP relay on one of the northbound interface of the new router (which points towards subscriber gateway) --DHCP unicast settings on the CPE devices Seems to have helped a lot, which leads me to believe it is much more related to broadcast than I previously thought.
