We also updated our DS920+ yesterday, and since then VPN isn't working.

Glad I've seen this as my VPN connection has all of a sudden stopped working. It was fine the other week but now, although it connects, I am unable to access the NAS by any of the android apps. Synology have really gone AWOL these last few days.
@AdrianEarnshaw I think I remember you had an SRM router. If it’s possible you could migrate over to VPN Plus on that, thereby making your VPN users external to the NAS, just like any other LAN device.
This is my preference as it keeps network functions on the router and content on the NAS.
Actually I maintain VPN Server as a fallback for VPN Plus.
Great memory. Unfortunately I can no longer use the SRM. I had fibre installed with VoIP phones, as they are moving away from copper telephone lines in the UK. Nice package deal so I thought.
I asked the question to BT could I continue to use my own third party router, they answered the affirmative. Turns out I am stuck with the crappy BT SmartHub2 otherwise the phones won't work. Been battling to get it all stable and am just about there now. So no more Synology router which is a shame as it was the best router I ever owned.
How about using the SRM as a LAN based remote access server? I’ve not investigated which mode would be best. I know that my LAN devices can connect to VPN Plus services so at worse you probably will be able to have it on the network using just the LAN interface.
