Noel is right in this case. I set up something similar with openswan some time ago. I do not want to route my local network traffic through the tunnel. Therefore I need a passthrough connection. Perhaps you misunderstood that… 

@Noel: I will later search the bug database and if needed fill a bug report. 

Kind regards
