sets default route, although server doesn't push that route!

[Ralf Hildebrandt]

Until recently, openvpn via network-manager was working fine (in jaunty). Now, all ove a sudden, network-manager-openvpn changes the default route to point into the tunnel, although the server doesn't push that route:

With a bare-bone openvpn call:

network-manager-openvpn 0.7.1~20090213+bzr14-0ubuntu1 is broken
network-manager-openvpn 0.7-0ubuntu1 seemed to work

[Ralf Hildebrandt (ralf-hildebrandt)]

Seems to work with 2.6.28-8-generic #26-Ubuntu

[Ralf Hildebrandt (ralf-hildebrandt)]

Turn out I was wrong, it's still there

[Lionel Porcheron (lionel.porcheron)]

Looks like a duplicate of #279597, what do you think Ralf?

Yes, I would think so.
But it used to work for me in intrepid, so...

Same here. When I connect to an openVPN network using my Jaunty machine the default route is replaced for the VPN address.
