I reinstalled network manager vpnc
and re entered general settings info only.
left everything else alone and it worked.

I did this today with Xubuntu 14.04.

I had to install the network-manager-vpnc-gnome package (which depends on a few other packages) in order to get the required options to appear in the NetworkManager applet.

I downloaded Sonic's Cisco VPN Client for Linux, but I didn't install it. Instead, I extracted the Sonic.net.pcf and rootcert files from that archive. The .pcf file guided me in what settings to use in the open source client, and the rootcert file is necessary for authentication.

In the NetworkManager applet's Network Connections dialog box, I chose Add, Cisco Compatible VPN (vpnc), and clicked the Create.. button.

The settings I used:

Connection name: Sonic.net VPN
General
☑ All users may connect to this network: Yes
VPN
Gateway: 208.201.249.242
User name: <my main sonic account username>
User password: <my main sonic account password>
Group name: Enhanced VPN
Group password: enhanced
☑ Use hybrid authentication: Yes
CA File: <the rootcert file that I extracted from Sonic's VPN client>
Advanced...
Domain:
Vendor: Cisco (default)
Version:
Encryption method: Secure (default)
NAT traversal: Cisco UDP
IKE DH Group: DH Group 2 (default)
Perfect Forward Secrecy: Server (default)
Local port: 500
☐ Disable Dead Peer Detection: No
IPv4 Settings
Method: Automatic (VPN)
Additional DNS servers: 208.201.224.11, 208.201.224.33
Routes...
(no specific routes here)
☐ Ignore automatically obtained routes: No
☐ Use this connection only for resources on its network: No

Once those settings were saved, I activated my new VPN connection in the NetworkManager applet, the VPN was established, and my routing tables were updated appropriately.
