sorry for late answer.
It doesn't matter wich way is he using the mt box in his side.
If it's routed it's better. If it has a nat on it, it's the same.
Use a simple queue on it for limiting. And put whatever ip you want on it, but make it fixed for simple queue to work. Or, put a second ip on gateway (yours) and give to the client the whole subnet on wich the new ip address is.
As a cpe, its' just that simple. If you used any mt as an ap, do copy the configuration on the wireless, and change the mode to
station. It's the simplest way. If you copied the wireless part of the ap on wich it connects, it should be connected already. ( if you do it from cli, do remove the MAC part from the command, or strange things will happen with duplicate mac's....

) Also, don't forget to set security profiles. It's just so much better to kick off the curious ones at the beggining, and to harden for the knowingly ones to bust you.
