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.

% Password expiration warning.
-----------------------------------------------------------------------
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 <myuser> privilege 15 secret 0 <mypassword>
Replace <myuser> and <mypassword> with the username and password you want to
use.

Cisco Router and Security Device Manager (SDM) is installed on this device.
This feature requires the one-time use of the username "cisco"
with the password "cisco". The default username and password have a privilege level of 15.
Please change these publicly known initial credentials using SDM or the IOS CLI.
Here are the Cisco IOS commands.
username <myuser> privilege 15 secret 0 <mypassword>
no username cisco
Replace <myuser> and <mypassword> with the username and password you want to use.
For more information about SDM please follow the instructions in the QUICK START
GUIDE for your router or go to http://www.cisco.com/go/sdm
