how to apply the station bridge mode in wds...

Hi…

i try today, when the link configure under the wds mode…
AP=> bridge mode
CPE=> station-wds

we can see in the AP, there is wds and wireless registration for the CPE.
but when i change the CPE to station bridge mode, i only see in the wireless registration there have the CPE wireless mac address.

but i not able to ping to the CPE and also not able to winbox it.

some thing wrong here?

thanks.
