That looks good; thanks.

It looks like it's making a simple HTTPS connection to the server, from
which it'll be downloading some configuration information and then
setting up an IPSec connection.

Can you point it at a secure web server of your own and see the query it
makes (you can do this with openssl s_server from the command line).

Then make that same query to the 'real' server and see what the response
looks like.... basically play man-in-the-middle until you can see what's
going on.

With a bit of luck you should be able to come up with a simple wrapper
which makes the HTTPS request to the server to get the details, then
invokes vpnc...
