Hello friends
My networks running well as public, local, map-to-local-one, hotspot, pppoe and Radius server [userman] for AAA hotspot and pppoe on one pishical interface to far... far... ways [over wire and unwire]....it's very nices. with centalized AAA....
Just to ask:
can userman block or additional rule or filtering, when user authenticated[hotspot] than it user too trying login from pppoe must reject....?
how to make policy it acident, can you give me advices.....?
I think mixing HotSpot and PPPoE on the same interface is not good. If you will use apparently PPPoE server and HotSpot server on different interfaces, than PPPoE users will be able to connect only to PPPoE server (do not set IP address or DHCP to PPPoE interface), as well HotSpot interface will not accept PPPoE clients.
In my opinion this question is not related to User Manager.
you are is best friend, and thanks for your suggested,
but, i must used like that, if not ....! how many $ must place for infrastructures.
again, thank for your opinion..
i think you are good opinion but, i don't like it, so..sorry.. 
You could use virtual wireless AP’s using different SSID’s. One for hotspot and the other for PPPOE connections. Just a thought.
