Network manager doesn't work anymore with two VPNs

[Saverio Miroddi]

I have two VPNs, an openvpn and a cisco.

Until 14.10, I could use them both, using `nmcli con up` twice.

Since when I moved to 15.04, the two calls succeed, but the cisco VPN doesn't work - it acts like it's been not connected at all.
