Hi all,
I have a problem with this configuration
MT1 >>>>> MT2 ----- MT3 >>>>> CPE

where >>>> is a wireless link and ------ is a cable link. MT1, MT2 and MT3 have two wireless cards and one eth interface each.

MT1 and MT2 are in bridge on their wlan1 interfaces, following what explained here [url]http://wiki.mikrotik.com/wiki/Transpare ... o_Networks[/url, with MT1 in "bridge" mode and MT2 in "station wds" mode. MT2 and MT3 are connected via a switch.
There are two bridges:
Bridge1 that includes MT1 (eth1, wlan1) and MT2 (eth1, wlan1)
Bridge2 that includes only MT3 (eth1, wlan1, wlan2)
Bridge1 is inserted into WDS link (MT1>>>>MT2).

Since yeasterday everything worked fine, but suddenly it stops!!!
The problem is that MT3 seems to be out of broadcast domain: I can reach it from MT1 on its IP address, but I cannot see it via "IP neighbors" utility, and I cannot receive PPPoE authentication requests on MT1 from CPEs anymore..

Any idea about the problem ?!?!?

Thanks

Do WDS mode, you cant use CPE in bridge mode.

Thank you Dallas,
the problem was a switch (Zyxel) that connects MT2 and MT3: I've simple rebooted it and everything went ok...
CPEs are configured as normal AP client in NAT router mode.
