Why the Repeater's MAC Address not the LAPTOP's?

Hi, I'm using a DWL-G710 dlink repeater with DWL-7200AP dlink access point.  Network diagram is: laptop -> repeater -> access point -> router -> internet Our router requires the MAC addresses of multiplelaptops connecting to the repeater for access monitoring but for some reason the router sees the MAC address of the repeater.  Is this a problem with the repeater? Thanks, Bench -- bench brought to you by http://www.wifi-forum.com/

Not entirely sure I understand what the problem is...

If you are using MAC address filtering, then you need to specify all
the MAC addresses that appear in the wireless traffic. A repeater is
an implementation of WDS (Wireless Distribution System) described in
IEEE 802.11, and the MAC frames in such a link have 4 address fields.
The are (informally) the original transmitter and the final
recipient, and the transmitter/receiver of the current intermediate
hop [1].

So to get MAC address filtering to work you will need to specify the
MAC address of both the laptop ans the repeater.

Hope this helps

[1] More formally, the MAC addresses are:
  DA Destination Address
  SA Source Address
  RA Receiver Address
  TA Transmitter Address
