[-- Attachment #1 --] My goal is to setup a p2p connection between the host and a guest vm and use the host as the nethop for the vm. I'm uskng bhyve for this setup: 1. on the host i create a tap tap0 interface and assign to it the IP 10.1.0,1 2. i create and start the vm using vm-bhyve. 3. in the vm I set the vtnet0 interface to 10.1.0.2 and set the default router to 10.1.0.1. i can ping the host but nothing up. When i run tcpdump on the host for this interface i can see the ping reply coming but it doesn't go to the guest. Any idea what's wrong? could it be related to the setup of the console port in bhyve? -l com1,stdio . Thoughts?
