Multiple Radius server for failover

michael.k

Hello all,

I would like to setup a second Radius server for WPA2 Enterprise authentication under:

Wireless Protection -> Global Settings -> Advanced -> Radius Server

 

This is a single point of failure and I don´t know how it is possible to configure a second Radiusserver.

The possible use of a Radius proxy just move the possible single point of failure to anoter system.

Has anybody a solution for that?

 

Thanks in advance for your help

    Hi René,

    You can't use a regular Network Group, but you can use an Availability Group in a RADIUS server definition on the 'Servers' tab of 'Authentication Services'.

    Hi Bob,

    Thanks for your answer, unfortunately in advanced enterprise authentication for WLAN i can’t choose a different server rather then the host definition I created as a radius server.

    I’m not sure why it only shows this single host definition when trying to change the server for wlan.

    The availability group has been created already for normal radius authentication used by VPN or webadmin/usersdmin Portal and world fine.

    René, you're going to do a facepalm when you see that you were stuck in an incorrect thought process.  Change the server definition used for advanced enterprise authentication on the 'Servers' tab of 'Authentication Services' so that it will use an Availability Group instead of a Host.

    Cheers - Bob

    Be careful with such a configuration and test yourself completely
