Cisco 1811 Dial Backup

[KlediBodinaku24]

Greetings

I need to create a dial Back up connection that comes from a Cisco 1811 running c181x-adventerprisek9-m 12.4 (6)T7.

The router has 1 interface connected that communicates with the Home Branch through a service provider. The router has a VPN connection with a router of the same version.

Since the first router is distant and i have been having problems with the line i need to create a dial backup configuration that automaticaly will dial the Service Provider Router that connects directly to my Home Branch and after that i need to create a VPN form my remote Router to my Home Branch Router.

Any help please

Also of secondary importance, is it possible that when the dial backup is on i can allow only one PC to communicate with the Home Branch

Thanks for you help

I have an 1811 configured for dial back-up with the following attached configuration. The only problem is that I need the cable from our DSL provider to be physically unplugged before dial back-up kicks in. Maybe this will help you :
