I have installed Cisco 3745 router with NM 8A/S module at central location which is connected to the PSTN network for dialup connectivity. Now remote users are connecting to central location through PSTN dialup connection.
Is it possible to do some configuration at central cisco 3745 router so that a specific telephone number subscriber can only make dialup connection to a specific NM 8A/S port.i.e. is it possible to restrict the diaiup users based on their telephoine number at the central router.
Also is it possible to create GRE or IPSec tunnel in this dialup connection.
