Forward Radius Authentication Request To A URL

Actually I have two issues. But, here I'm concerned about the Irule:

 

 

1. Irule: An external device is authenticating via Raduis UDP to our primary site. But, we also need it to authenticate to our secondary site. If I put in the URL (on the internal GTM, that will has both of the radius virtual servers), the device automatically picks up the primary virtual server - the device won't allow me to input the URL on the GTM. Maybe using this URL isn't possible, since I'm using radius UDP?Since both radius devices are at different sites, I can't use a pool member. It looks like I have to use the GTM/Irule?

 

Do you know if this is possible with an irule? Maybe I'm wasting my time.......

 

 

2. Issue 2 is that I need to configure a virtual server with UDP radius.

 

 

Thanks
