Brigde & PtP

Hi guys,
I have a question and I would be very happy if you guys can help me ...

I have this setup ...

Customers <-> Mikrotik <--- PtP ---> Mikrotik <-> Linux Gateway <-> Internet

Ok ...
I'd like to make my customers' MAC addresses reach my Linux Gateway ... I was reading the if I make a bridge between the Mikrotik2 two interfaces that would be possible, but the wlan interface is in station mode because the ptp and this wouldn't be possible ...

Is there any other way to do that ?

Thanks

change from station mode to station-wds, then bridge ether1 and wlan1 on both the station side, as well as the AP side.

Hi ForePoint ...

Thanks for your answer ...
Just one more question ...
Changing it to station-wds, does it loose performance ?

Thanks again,

maybe a little, depends on the CPU of the router, it takes a little more cpu power to run wds.

Or, if you want keep the external party on a different subnet (a really really good idea), just route between them using static route at each end, as in my picture: http://forum.mikrotik.com/viewtopic.php?f=7&t=19568
I use: Subnet for each customer site [/29], one for the backhaul mesh[/24], one for my server room[/24]

I'm sorry ... I haven't understood ...
Are you telling me to create a static route between my ethernet and wlan cards to pass the MACs through ?

Sorry ...
Thanks,

Yes. It may be inefficient (thoughts anyone?) but it works well for me.

Any traffic destined for the remote network gates to the remote radio and the remote router knows what to do with it. You can then manage/audit/filter based on source network address.

WDS uses the BW more efficiently but, from my understanding, wants to bond with a bridge at each end... effectively creating one integrated ethernet layer across everything...a bit scary.

[That said, ForePoint's method is well documented on the Wiki and possibly makes better use of BW]

the only thing that is inefficient in your setup is IP utilization, however it will not work for what marcelocbf needs to do, as it will not pass the mac layer from the client to/through the AP. In order to pass the mac layer, he must use station wds, or setup EoIP tunnels (which add alot of overhead).
