VPNC not connecting when on Company's local network

Here is syslog from start of using NetworkManager to connect to my company's network to when the service failed to connect:

VPNC can connect from a home network connection or from a coffee shop, but not from the network at work (either via wireless or wired from the work DMZ). This started happening on trusty just about 1 week before the upgrade to utopic (I do distupgrade regularly). I upgraded to utopic thinking that it might be fixed there... but it was not.

I did contact my network admin who monitored the exchange, and he said that my RSA token password was accepted... even though my machine said the connection could not be established.

I can access the VPN at work using my iphone's native client and junos; so, I believe that the fault is vpnc. Any help you could provide to help me debug why connections are failing to be established would be appreciated.
