Router Hangs

[sreekanth sarma]

Hi all i am using 2801 router with 14 Mbps internet. I am presently facing a very new problem the router hangs down after working for half an hour and no packets will be delivered and total internet service is down and the link successfully works when i use proxy server (ISA) as the router and use two NIC cards and use the nat over it it works fine.

can any one give me solution ? i am attaching sh version of router

i will recommand to configure the router to send log messges to one syslog server (that you should install in your PC for example), may be you can collect usefull informations.

also when rtr hangs access it via console or telnet and see what you obtain from show ip interfaces brief and show ip route.
