While WDS bridge is completely transparent (i.e. ethernet frames across bridge 
maintains original source mac-address), as far as i have read on dd-wrt docs 
(http://www.dd-wrt.com/wiki/index.php/Wireless_Bridge#Limitations and 
http://www.dd-wrt.com/phpBB2/viewtopic.php?t=68) Client Bridge and Repeater 
Bridge mode are not so transparent, so that every packet coming from the 
Repeater/Client side has AP mac-address as source (as a result of 802.11 
protocol specifications), and that's confusing coova which give the same IP 
address to all  the clients associated to the repeater.
Sniffing traffic with wireshark on the coova host shows dhcp request packet formed 
as described earlier: i can provide it to you if you need it and i can help 
with more tests
