We have Cisco 1841 as the data router. We have assigned 2 secondary gateway ip on this router. This router has default route to the Firewall for internet traffic. Now the problem is only for the users with secondary IP as their gateway. (The secondary IP was given since that is a different subnet). Suddenly the users with the Sec. IP gateway cannot browse to the internet. When we login to the router and clear the arp from the router, everything works fine. This does not happen very often.
I am out of ideas with such problem. Please guide.
Thanks in advance.
