I have Googled a lot of hits for this problem, but so far I haven't seen
a case that matches my scenario.
I have a FreeBSD 11.2-STABLE system running vm-bhyve-1.2.3 with neither
firewalling nor NAT in use.
The primary symptom that I'm seeing is that the Windows guest sees no
internet connectivity through the virtual Ethernet interface. The
Windows DHCP client is not able to obtain an IP, even though there is
DHCP service available on the host's bge0 public interface. If I
manually configure an IP on the Windows host that is from the same
subnet as the bhyve host, then I *can* ping IPs on the physical host
(there are two, one primary and one jail IP). But I cannot ping any
hosts on the subnet, including the LAN gateway IP.
Some configuration information follows. Please let me know if I can
provide more.
Thank you!
Jim
