I have some public NAS(free without pay) and some payment NAS (hotel).
It’s possibile to ensure that a “free user” can browse on certain NAS (free) and not on others(hotel)?
As a paying user navigates on everyone?
Yes. In the radius radcheck table, you can enter attribute=WISPr-Location-Name with value=free for users that are using the free system. Then in the free routers:
/ip hotspot profile set 0 radius-location-name=free
In the paid routers:
/ip hotspot profile set 0 radius-location-name=paid
Users without the WISPr-Location-Name assigned can login anywhere.
