MAc Clone with Pseudobrige

I have a hotpost with mac autentificacion. I had to connect a Mikrotik with other wireless equiment that doný support WDS so I had to use mode psuedobrige of ROS3.

The problem is that all the customer conected thorugth the bridge have the same Ip in Hosts of the hotspot son I can’t make a mac login.

Somebody khows how to solve this?

Thanks,

Txema…
