Hi list.
I was wondering, how can i Drop or Accept the Arp and Rarp packets with
IPtables?
Is there any special command about Adress Resulution Protocol?
Thanks a lot...

Thanks for your fast answer.

I'm already using the Ebtables. Really good tool for Layer2 Frames and
many other Protocols. I can catch Arp Packets with Ebtables. Moreover
Ebtables has got only few option about Arp packets. But I need the use
IPtables. Because I have to redirect some Layer3 Packet (include ARP
packets) with IP header.

Hello,

You cannot. ARP packets are not IP packets. The ethertype, protocol and
packet format are different.

arptables.
