ubuntu 14.10,networkmanager and openconnect

[Nuxx]

Hello,

Ubuntu 14.10 Lenovo X240.
network-manager-openconnect 0.9.8.6-1ubuntu2
openconnect                                          6.00-1

over Wifi, networkmanager manages okay openconnect vpn, but using build 
in 4G internet, it wont add default route anymore.
using USB tongle 3/4G works fine.
using command line openconnect vpn.myserver.com works fine.

i think there a problem with interface name wwan0 what internal 4G 
creates. usb tongle uses ppp0
