Can I configure an IOS router to dial out on a scheduled basis? I have 25 sites that I want to dial out every night at midnight and stay up for 30 minutes so I can make updates to the configuration. None of them have broadband and they are all dial on demand with ports 53, 80 and 443 as interesting traffic

Is this possible?

Create a time-based ACL that only permits the traffic you mentioned above. Configure the time-range command to be effective only between midnight-12:30am. Associate the ACL with the dialer-list configured to trigger the DDR traffic. Ofcourse, for time-based ACL to function accurately the router should derive the clock from an NTP source.
