Yes, that is what I thought: that a new virtual device would be created
(say eth2) that would be bound with the ip address and gateway
information that is provided by QuickVPN. This is the step I'm not
seeing. And being that I'm establishing the VPN connection via QuickVPN
and it's a windows application I shouldn't expect that it would create
My assumption is that QuickVPN has in fact established the connection
(as is evidenced by QuickVPN and the log files on the VPN router) but
that it has no way to hand off that information to linux. Again, just a
wild stab in the dark.
At any rate, it seems my best bet will be to use a windows PC to
establish the VPN connection, then use ssh to connect to the windows box
with my linux lappy. Then I should be able to run tightvnc to connect
to my workstation desktop...
Let me know if you come up with anything more direct.
