Kai,

I hope you see the problem too. After establishing the
vpn-connection you have 2 default routes (the last 2 lines)
As it will always be used the first, your internet-traffic is now
going through the tap0 interface in the vpn direction which is
obviously not wanted.

A first workaround would be to delete the first default route with:

route del default gw 141.19.173.11

after establishing the vpn-connection.
