Dial-on-demand

I am using SuSE 9.0 and installed ADSL The Ethernetcard is installed as Accton Network Everywhere Fast Ethernet 10/100 model NC 100 and configured as eth0 with DHCP DSL is configured as dsl0 provider Planet.nl At 10.0.0.138 I get a Speedtouch screen in which I can switch between connected and disconnected. Trying in Kinternet with Yast2 to configure dial-on-demand (as suggested in the Administration guide) with dns 1 as 195.121.1.34 and dns 2 195.121.1.66 (as suggested by the provider) failed. Can anybody tell me how to proceed to the desired state of dial-on-demand?
