I have a cisco 2611 and i’m trying to set up a small lan. I have a cable modem which I get the ip address on int e0/1 via dchp. my problem is that the nat only works for about an hour sometime more and sometimes less. It nevers stays on all day. If i hard boot the cable modem I can get back on-line temp. When I debug the nat I notice that everytime its not working its trying to get to the dns server and no other ips. PLEASE HELP THIS IS VERY FRUSTRATING
