Hi! Can any one PLS help me on this topic? i am receiving ARP broadcasts from our local net directed to the router. but the router's arp cache shows that approx. 70% of the ARP entries are incomplete as they are from the IP's that we r not using any where. also our bandwidth is often getting used up. this may be due to frequent broadcasts. i have to mention that we have 31 networks working in the local net. is it possible to filter BC packets using IPTABLES or in any other methods. and if there is any previous postings on this topic PLS Forgive me as i am not getting any time to search them.
