Configuring the network on the host system
In order to access a network interface of the host system from the vkernel, you must add the interface to a bridge(4) device which will then be passed to the -I option:
kldload if_bridge.ko
kldload if_tap.ko
ifconfig bridge0 create
ifconfig bridge0 addm re0 # assuming re0 is the host's interface
ifconfig bridge0 up
Note : You have to change re0 to the interface of your host machine.
