Hello, I have setup a Router with 3 interfaces as follows. eth0 -- External Network eth1 & eth2 -- Internal Network I am getting unusual ARP traffic continuously on both the interfaces. i.e I am getting ARP packets for every IP address in that subnet. How shall I restrict that packets from thos interfaces. I used ebtables for restriciting ARP traffic. For Eg ebtables -A FORWARD -p arp -i eth1 --arp-ip-dst 172.17.3.0/24 -j DROP Even then I used above rule , the packets are not dropped. Can anyone give me a way to stop that unusual ARP traffic from the network using some rules. Thanks In Advance Phani Kumar IIIT-Hyd India
