IEEE 802.11 protocol does not support bridging of a station mode
interface at link layer since it cannot send frames with any other
source MAC address than its own. As such, you would need to use some
other mechanism here like 4-address WDS frames (if the external AP
supports them) or some sort of masquerading NAT/proxy ARP etc.
