[Pkg-utopia-maintainers] Bug#805070: network-manager-pptp deletes default-route on connect

Sat Nov 14 10:41:20 UTC 2015

Package: network-manager-pptp
Version: 1.0.6-1
Severity: important

Dear Maintainer,

When i connect to the configured vpn, the network-manager deletes the
default-route to my router.

I have to add this route manually again with
route add default gw 192.168.0.1

When I stop the connection, the route to the vpn will not be deleted.

Before starting the vpn-tunnel:

Kernel-IP-Routentabelle
Ziel            Router          Genmask         Flags Metric Ref    Use
Iface

wlan0

After starting the vpn-tunnel:

After stopping the vpn-tunnel

Ziel            Router          Genmask         Flags Metric Ref    Use

It's the same, when i activate "use ressources only for this network" or
deactivate this option.
