Problem with hotspot and celular phone (android)

I have users who use cell (android) to enter the hotspot, the set have to do the automatic login by MAC.
The problem I have is when these phones come with your connection to the cellular data network (3G / 4G) enabled hotspot not valid for mac and redirected to the hotspot login page.

If I look at the menu of “host” 2 connections, Ip1 = ip mobile data network, Ip2 = ip hotspot (DHCP) appear.
In the log appears as invalid login for MAC

To fix this I have to go to “host” and remove the two lines corresponding to the MAC cell.


Any idea that this happens?
