AUtomatic connection with modem

Hi there,

my prob is that we need to connect one office to the internet via MODEM.
We would like to use a LINUX BOX to manage the connection.

We installed SUSE 9.0 => runs smooth!!
We set up the kppp to connect to our provider. => it works!!
We set up the routing and dhcp. = > both do run well!!

Now the thing is that a secretary should just switch on the Box and without
any login of a user the connection should start!!!!!

Is that possible????
Since I do not finde a switch to set in the GUI I am looking forward for
your advice.

Thanks
