Hyper-V 2012 and VPN on 2012 R2 breaking virtual switch

Good Afternoon,

I have a client that uses VPN on a 2012 R2 server which is a VM running on a Hyper-V 2012 R2 server.  For some reason it will randomly stop working and basically time out while connecting to VPN and the only fix is to completely remove the External Virtual Switch and then Create a new one from scratch which basically means I need to be onsite to do it since it disconnects my remote session when I remove the virtual switch.

The bigger problem is that we now have a client that wants VPN setup with the same 2012 R2 Hyper-V and 2012 R2 server setup but they aren't local, so I need a fix for this before I set them up with VPN since I won't be able to get onsite.

If any of you have advice on the matter that would be great!

Thanks,
Adam

Where is RRAS installed?

It's on a Server that is being used for files, PC Law, and Printers and is a Virtual Machine.  No roles have been installed on the server, however, except RRAS

So RRAS is installed in a VM.

Does the host have Broadcom physical NIC ports? If yes, has VMQ been disabled in the driver for all ports? If not, do so and that should help with the network issues.

It has HP Ethernet 1Gb 2-port 332i Adapter installed on the host server.  In the physical LAN drivers VMQ is turned off, on the Hyper-V team the VMQ is turned on.  I'm guessing the Hyper-V Team "NIC" it should be turned off as well correct?  Or does it only matter on the physical hardware drivers.

VMQ needs to be turned off in the adapter's properties (driver). The 332i is a Broadcom chip. The OS settings do not need to be touched.

OK then yeah it's turned off for both 332i units in the driver properties.

Most edge devices have a one or two user freebie license for SSL VPN included. Maybe that would be a better way?

Yeah we use Ubiquiti routers so I'll give that a shot.  It's still a bit concerning that this doesn't work through the server due to the NiC's in some way, or due to Hyper-V.  Whichever is the issue.   I feel like using the router as the solution for VPN is not actually fixing the real issue.  It bugs me but I suppose if that works then it works.

We've not used RRAS for VPN connections for at least ten years. PPTP and L2TP are a pain to use at the best of times and have huge overhead.
