help setup hotspot and usermanager on seperate routers

I want to change my Authentication method from pppoe server to a hotspot server with authentications coming from my separate usermanager PC.

Currently i have a large bridged network and i want remove the bridge from my High sites which serves clients and implement the hotspot on the AP.

Below is an example of what i want to do.

client))))((((Wlan1 on RB433 and ether1 connects to ether1 on PC usermanager ether 2 on UM connects to Internet

Wlan1(hotspot) must not be in bridge mode and run on a separate ip range to that of the ether1.

Can the Hotspot operate on a non bridged network and how do i get the clients to authenticate with the usermanager wich is connected to the ether1 on the UM PC?
Will there be routing involved? Please point me to a wiki i can follow.

Thanks

HotSpot can operate on non-bridged network, but clients should have direct (layer2) connections to the server.
It does not matter, where User Manager is connected (when there is public IP address assigned to the box).

Thanks Sergejs


I am following this wiki but seem to have run into some problems.
http://wiki.mikrotik.com/wiki/Centralized_Authentication_for_Hotspot_user

The Hotspot works fine but when i try to log in it gives me username and password error. Looking at the log it appears that its trying to authenticate from the hotspot server and not the Usermanager on the PC router.

Also looking at the radius Status on the hotspot it says 8 requests and 8 timeouts.

Hotspot IP(RB433)= 192.168.2.1/24
Lan IP (Rb433)=192.168.1.177/24

Usermanager IP(Pc router)=192.168.1.200/24

Do you have use-radius=yes for the HotSpot profile?
What configuration do you have at /radius on HotSpot router?
