ARP Cache? [Resolved]

[LeoniAquila]

If you go to Firewall tab → Advanced → Attack Detection Settings, there’s an option to “Protect the ARP Cache”. What is that? Should it be enabled? ARP Cache cannot be found either in the Help files or by searching this forum!

Search here or Google for “arp cache poisoning” to get a bit more information on why this can be important.

@http://www.tech-faq.com/arp-cache.shtml

The ARP cache is a table which stores mappings between Data Link Layer addresses and Network Layer addresses.

The Data Link Layer addresses are usually MAC addresses and the Network Layer addresses are most frequently IP addresses.

The ARP cache is stored in RAM by the Operating System.

Should it be enabled?

And like sded said, search for arp cache poisoning on Google if you want to know why this should be enabled.
