Dear All

I have Cisco 3745 router with NM-8A/S module and 12.3.IOS.

Hello Anand,

looking at your configuration, I can see that he peer default ip address pool you have specified under your Dialer 1 interface has a differnt name than the one specified in global mode:<

interface Dialer1

--> peer default ip address pool Dialin-Group-1

--> ip local pool Dailin-Group-1 192.168.16.201 192.168.16.208

Not sure if this is a typo, but the names both have to match. Can you try and change this and see if it works ?

Regards and Merry Christmas,

GP
