Hello I have looked in the internet but I have not been able to find a pratical example of the configuration that I need.
I have an 1841 router with 12.4(22) IPBASE IOS on it.
I connect to the internet using a sHDSL connection.
My interfaces are as the following:
FastEthernet0/0 109.168.2.xxx First of my public subnet /29 FastEthernet0/1 unassigned YES NVRAM administratively down down BRI0/0/0 unassigned YES NVRAM administratively down down BRI0/0/0:1 unassigned YES unset administratively down down BRI0/0/0:2 unassigned YES unset administratively down down Serial0/1/0 unassigned YES NVRAM up up Serial0/1/0.1 109.168.3.xxx Point to point
On the fast0/0 I have connected a firewall that does nat for all my lan.
Since the sHDSL link goes down very often, I need to setup a dialer interface to call out when the shdsl doesnt work.
Here is the config.

Cisco Router and Security Device Manager (SDM) is installed on this device and it provides the default username "cisco" for one-time use. If you have already used the username "cisco" to login to the router and your IOS image supports the "one-time" user option, then this username has already expired. You will not be able to login to the router with this username after you exit this session.
It is strongly suggested that you create a new username with a privilege level of 15 using the following command.
username privilege 15 secret 0
Replace and with the username and password you want to use.
