GUI network-manager-vpnc doesn't connect over wired connection only
I have a problem with a user's laptop running Ubuntu 8.04 and network-manager-vpnc. I cannot get vpnc to connect to our corporate network via the gui interface and a wired connection only (wireless works fine). With ethernet cable plugged in, I click on the NM icon at the top right, select vpn connections and then select a profile that I created (and recreated) that has all the correct settings to vpn into our network. But nothing happens. No error message, no asking for passwords, nothing.
If I run vpnc-connect from a command line and use the correct settings, I connect just fine. Again, this only happens when connected via ethernet. It works fine when using wireless.
Anybody have any ideas?
