Hi. I've just got some VPN software, the vyper package. I'm struggling to set it up, as I keep getting an error message. I've been googling all afternoon and some support sites seem to suggest I need to make changes in system prefs, but I've had a play around and nothing is working. Has anyone on here got it working and wouldn't mind going through the setting with me? I'm just terrible at network stuff and I'd be hugely grateful. I've pictured the error message I keep getting, and the SP page where the settings are, in case that helps. Thanks.
