Force radius requests from management interface

Running LTM 10.2.1, attempting to set up login authentication to a Radius server. I want the Radius server, which is on 10.240.5.20, to receive the requests from the management interface, however it seems to be fairly random whether the requests are sourced from this or the F5-INTERNAL-DMZ interface. (In fact, I don't mind which interface the requests are sourced from, as long as it is consistent).

 

 

The LTM doesn't seem to respect the route to 10.0.0.0/8 from its F5-INTERNAL-DMZ interface. What do I need to do to get some consistency?

 

 

 

The interface addresses and route table are below. Any help gratefully received.

    you will need a b mgmt route statement to send triaffic to the radius server. for example:

     

     

    b mgmt route 10.240.5.20 netmask 255.255.255.255 gateway 10.240.6.1

    Hi Rob

     

     

    I'm trying as well to authenticate users via radius.

     

    I use windows radius server and I'm not really familiar with radius.

     

    Could you help me please?

     

     

    Or what kind of radius server do you use?

     

     

     

    Best regards
