F5 with TACACS+ Cisco ISE for users authentication

Hi Guys,

 

I'm trying to setup F5 TACACS+ authentication against Cisco ISE, however I notice my F5 is using external interface's IP to communicate with Cisco ISE, is there a way to tell F5 to use mgmt or internal interface's IP to communicate with Cisco ISE instead of external?

 

Thanks.

  • You probably have default route from external interface so this is the interface used.

    You can create mgmt routes if you want to use mgmt interface or more specific route from any other interface.

      You're right. It was the route. I added a route for mgmt interface and it works. Thanks.
