Hotspot routers to use centralized UserManager

hello,
i have 5 diffrent sites that i want to centralize the radius server for them, but their IP addresses are LOCAL,
i read in the wiki, that i must put the HotSpot router IP address…
my centralized MT UM has public static IP
to add a HS router, in the wiki:
/ tool user-manager router add subscriber=MikroTik ip-address=x.x.x.x shared-secret=123456
where the ip-address= local HOTSPOT ip address in my case..
will this work?? or it has to be public and static??

Hi,
Best Example as per your Requirement. Pl Refer
http://wiki.mikrotik.com/wiki/Centralized_Authentication_for_Hotspot_user

hi, thanks for the example,
i saw in that example that the Hotspot Routers PUBLIC IP was added to the UserManager Router, which make sence..
but in my case, the public interface is either a local ip address, or dynamic public ip address…
any solutions for such case??

thanks.

Hello,

i did VPN connection between the 2 routers so that the HOTSPOT (client) have an ip address that i always know, and i added the server IP address in the radius server,

i tried the following:
on the server: when i add tool/userman/router the public IP of the Hotspot
the hotspot can communicate with the UM radius

on the server: when i add tool/userman/router the PPTP IP of the Hotspot
the hotspot CANNOT communicate with the UM radius , i get radius server not responding message

please how do you people do it? do you always have to have STATIC ip address at all HotSpot Clients? or there is away???

thanks.
