While it is/was a personal use/experiment I have used all the following under Windows 10 Pro's Hyper-V with networking via hn0 Ethernet as seen from the guest FreeBSD: releng/11.1 (no longer around to remind me of the most recent -r?????? but various updates ) stable/11 (various updates, -r320807 currently) head (various updates, -r323147 currently) I had no problems with my use. (By no means a traffic match to your context but definitely used.) In all cases the Virtual Switch Manager was tied to the (builtin) "External network" that is listed as: Intel(R) I211 Gigabit Network Connection in the Virtual Switch Properties pop-up for External network. The machine is not a server. So not totally broken as far as I can tell. Something more specific to your context would seem to also be involved. Hyper-V has worked nicely for assigning 14 of the machine's 16 hardware threads to FreeBSD and doing buildworld buildkernel and poudriere based port builds. (Windows 10 Pro not being otherwise busy.) =3D=3D=3D Mark Millard markmi at dsl-only.net
