I'm fairly new to the Cisco world, and my latest project is to increase security on the network. It was identified that our Access Server should dial-back / callback users when they try to access the network from outside. I've gotten alot of information on how to configure callback clients, and some on configuring callback servers. However, i need a little guidance with respect to this task at hand.
Is there anyone that can give me the configuration adjustments to be made to get myCisco AS2509-RJ Access Server to call back clients?
Please find attached the current config.
