Cisco 2600 Router & T1 Timeout

[Robbo19]

Hello,

I have just started at my position here at work. We have a problem that occurs every weekend. We have a T1 connection, and every Monday morning, someone needs to reload the router in order for the internet access to work again. It seems to occur after about 24 hours of nonuse. It may sound like something easy I am overlooking, but when I asked everyone here why does this happen and why haven't they fixed it yet, well... nobody knows. So any help is appreciated.

do a show config and also post a sh service-module, sh int serial 0 or what ever your interface and a sh frame-relay pvc. Jeter@LasVegas.com

[jeter]

well your interfaces look ok only because of the reset of the router a day ago. Now your ip's addresses are 208.255.114.138/29 this gives you 8 static ips
network 208.255.114.136 available 137 thru 142 your broadcast is 208.255.114.143/29. To start I would change your ip route to this ( ip route 0.0.0.0 0.0.0. 208.255.114.136 ) make sure to keep your old commands just in case you have to change back. What is your application here I see a lan ip to a public and nat for the others. Jeter@LasVegas.com
