I have a Cisco 2610 connected to a fw via a hub. Occasionally I'll lose my connection to the internet and will have to manually clear the ARP cache on the router.(resetting the ARP to the FW) This solves the problem. Does anyone have an idea what may be causing this?
 
sounds to me like some device is stealing pr spoofing your mac addy. do you have a catalyst on your network? do you have advertised routes that are invalid? are you sure there's no blackholing with your routes? is the 2610 conf. w/ "no ip directed broadcast"?

Thx jason.

It turned out to be another device w/ the same ip.
