    I have an AS5300


    Cisco Internetwork Operating System Software
    IOS (tm) 5300 Software (C5300-I-M), Version 12.2(16), RELEASE SOFTWARE (fc3)



    This is a machine that I inherited which allows users to dial a number which comes in to the Cisco via a PRI and gives them an IP address, allowing them internet access.



    the problem I am having is that users can dial via their PC modem and they get an IP address assigned to them from the Cisco. But they have no internet connectivity at all. They are not even able to ping the very cisco that gave them they dialled into



    I am pretty new to Cisco in general, so any kind of information would be useful, including debug methods and commands. Pointer to sample configurations would help out a lot as well. Below is my config
