What does ifconfig on the host show?

Also vboxmanage showvminfo <vm_name> | grep MAC (replace <vm_name> with the virtual machines name (win10vm?))

According to VirtualBox NAT documentation, VirtualBox acts like a router for NAT configured virtual machines. This "router" is part of a "VirtualBox networking engine". This engine maps traffic from and to the virtual machines (internet <--> host <--> guest VM), without creating network interface on the FreeBSD host (like wlan0).

How exactly the VirtualBox network engine taps into the FreeBSD hosts network I don't know (I haven't found any information despite some research).

Following links explain schematically how NAT (and other types of networks) on VirtualBox works.
