Shared radius server

RouterOS General
1

Hi all,

I have 2 routeros servers now, and I would like the second server to use the same radius server as the first.

I thort I knew how to make it work, but obviously not, I keep getting radius time outs.

Is there anybody who has done such a thing? Is it possible?

Thanks.

Is there NAT between your routers and the radius server?

I haven’t set up any NAT at all, just the masq rule for the clients to get access to the net.

I’m not asking about NAT on your MikroTik routers but if there are any other routers between your MikroTik routers (which are the radius clients) and the radius server, and if there is NAT on any of these other routers that may be between your routers and the radius server…

oh, oops, sorry, no there is nothing between them, just a normal hub.

\

Mikrotik1|-----|HUB|------|Mikrotik2|------|Test Client|

In the hub is the AP, some other clients are also connected straight to the hub. Now for testing purposes, I have a test client, but trying to connect I get a radius time out on the system log of Mikrotik2. Mikrotik1 says nothing.

I’m missing the radius server in your network picture…

Where/how is it connected?

The radius server is sitting on mikrotik1

Ok, so you’re using the RouterOS integrated userman package as a radius server?

  1. Make sure second router can access first MikroTik router, where User Manager is installed. Check that you can ping one from another.
  2. Make sure you have added second router to the ‘tool user-manager router’ list, and RADIUS client is configured properly on the second router.
  3. Check that RADIUS data is not blocked by the any firewall on them or between them.

Tom,

Yes I am using the radius for userman on Mikrotik1.


sergejs,

Thanks, I will relook over my configuration, I must be missing something, I did add the second router to userman, but I guess I am missing the radius client config then.

This is done on the radius option on winbox? or is this another setting I need in the console?

Yes, you can apply radius configuration in Winbox ‘Radius’ menu or ‘/ radius’ in CLI.
User Manager documentation on the wiki provides the configuration for the User Manager and remote routers configuration,
e.g. http://wiki.mikrotik.com/wiki/User_Manager/Hotspot_Example
