Good afternoon! The scheme: Base station (wlan1) - client AP - client PC. With a connection of problems is not present. When in a role client AP the transparent bridge (Tellus A14, GL2411AP, D-Link 2000), that is any AP which does not substitute the mac-address for work in a network client PC not ping acts.
