Thanks Daniel

So the "phys" is not compliance with "Virtual interfaces" ?

When you said : "Note the container won't be able to communicate with
the host."
is container can communicate with the world ? and is container should be
contacted by the world (except the host) ?

i have tried using veth+ bridge but it is not compliance when running
LXC containers on host virtualized by ESXi
Containers can communicate with host but did not communicate with the
entire network.

Best regards
