HELP WITH CISCO 2611 ARP

Hello,

I have a cisco 2611 that has a problem connecting to the firewall. The router and firewall are on the same subnet, and for some reason you can't ping firewall from router and you can't ping router from the firewall. After couple of hours messing with the router, I found out that if you clear the ARP it works fine, however after couple of minutes it goes back to no connections. All other devices on the network where the router is located are accessible at all times, except for the firewall which in order to access it I need to clear the ARP every 2 or 3 minutes. Any advice or help???

Thanks in advance for all your help, and happy holidays.
