MinimServer stopped on Synology NAS

[Bronx54]

Sorry not sure how to get this information, not very savvy with networks, my NAS drive connects to an Apple airport extreme router via a Linksys 8 port gigabit switch. Internet connection is through a Draytek Vigor 130 modem.

I have looked through the DS115j settings and parameters and cannot find any reference to VPN settings, I have also looked at the Airport Extreme and cannot see any reference to VPN settings.
