I don't have anything capable of running Hyper-V on Windows Server (R1 or R2) nearby so I can't easily confirm the issue, but from the sound of the FreeBSD bug report it's a known issue and has already been fixed upstream.

If it works on Windows Server 2012-R2, what's the incentive to go out of our way to pick up a fix so it works on an out-of-date version of server 2012-R1?

We will eventually get the fix once it is in a FreeBSD branch we release from, that may be pfSense 2.4, might be 2.4.1, it depends on if the fix makes it into an errata release on FreeBSD 11.0. In the meantime, if pfSense 2.3.x works there, that can be used for the time being.

I'll leave this open in the meantime in case the fix comes in from FreeBSD along the way to 2.4

This seems to be relevant commit -
Assign to Luiz for evaluation to make sure it can be cherry-picked

This is not so easy, there are a lot more relevant commits to MFC, a lot.

  • Status changed from New to Rejected

There is no much we can do at this point for a release that seems to be unsupported by Microsoft according

If you need to stay using R1, you will need to stay on pfSense 2.3.x. If you need to run 2.4 you will need to upgrade Hyper-V to R2
