Arptables
Encyclopedia
The arptables computer software utility is a network administrator's tool for maintaining the Address Resolution Protocol
(ARP) packet filter rules in the Linux kernel
firewall modules.
The tools may be used to create, update, and view the tables that contain the filtering rules, similarly to the iptables
program from which it was developed. A popular application is the creation of filter configurations to prevent ARP spoofing
