Creating a physical interface did not communicate with the network

I’m trying to create a network physical connection on my host using this command:

lxc config device add ctn-001 tap10 nic name=eth0 nictype=physical parent=brvlan7

The interface is attached fine to the container but I dont have external communication inside the container.

If I use for example other type of interface everting works fine:

lxc config device add ctn-001 tap10 nic name=eth0 nictype=bridged parent=brvlan7

Obs. I need to have the same tap MAC address inside the container because of the DHCP.

lxc config edit ctn-5b3135e252aa80-93343168
