Title:
  No dns resolution after closing a vpn/pptp connection

Status in ppp package in Ubuntu:
  Confirmed
Status in ppp package in Debian:
  New

Bug description:
  step to reproduce

  set a VPN connection configured to connect a Microsoft vpn server
  (pptp)

  internet acces is ok

  enable the vpn connection using the applet on the top right corner of
  the desktop

  internet still ok
  ping works

  disable the vpn connection

  ping doesn't works with a host but works if i specify an ip address

  ping: xx.net: Nom ou service inconnu

  As a workaround, i disable the ethernet link and re-enable it

  name resolution is now ok
