Thank you for quick response, I see what you mean now... I confirm that I can see the bridging interfaces and can sellect them as intended when I select on of the following in: the eth interfaces Edit --> General window: At Boot Time --> STARTMODE='auto' On Hotplug --> STARTMODE='hotplug' In both cases Yast keeps the configuration as intended when revisiting it in Yast. Thanks again for the explanation and I agree with your proposed course of action. Tomas
