We have been experiencing slow internet speeds at work. So I started investigating and was using the Colasoft Capsa program.

I found that when doing a security analysis with this program that it said we were under ARP attack.

I found a article on the Colasoft site on ARP spoofing. http://www.colasoft.com/capsa/troubleshoot_arp_attacks.php

When looking at the physical endpoint (Solution 4:) example I found the mac address of our Cisco Small Business RV042 10/100 4-Port VPN router with about a 100+ IP addresses linked to it.

I jumped on the cisco site and the closest thing I could find to helping me is http://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-protocol-snmp/13495-clear-arp.html

However to my knowledge this won't work on this router since we only have access to the GUI interface.

Can anyone confirm that this is indeed a ARP attack on this router?

If so how do I stop it and protect this router?

Any help guidance is greatly appreciated!
