What do command do I enter to start a pre-configured VPN connection?

I am trying to set up the synchronisation/backup program that I use on my desktop/laptop which synchronises my files on my university's servers. In order to connect to my network share I first have to connect to the University VPN. I'd like to automate this in the synchronisation program and I'm hoping someone can tell me what to enter in the box (see screenshot). I'm guessing it would be the same as what I'd enter into the Run dialogue to do the same thing.
