I'm trying to figure out how to send a CoA from freeRadius to the NAS. The set-up I have involves two servers and an Aruba controller.
i.e. proxying CoA packets through FreeRADIUS to the NAS. While this should work, it's not a deeply tested scenario.
In this test set-up the client authenticates locally on the freeRadius server. The server listen on port 3799 for a CoA request that is generated from another computer, the freeRadius accepts the request and sends a ACK to the generator but it does not send anything to the NAS,
Did you configure the server to proxy the CoA request? Look for "proxy" in raddb/sites-available/coa in 2.1.9.
I tried to supply in the request a NAS-IP-Address attribute and also tried with Packet-Dst-IP-Address with no success. Also tried different things in CoA and Originate-CoA with the same results.
Well.. the "coa" documents exactly what you need to do. Trying random *undocumented* things won't make it work.
The goal I'm trying to reach is to supply the user-name in the CoA request that will force the client to silently reconnect and in the meantime I will have changed the Access-List accessible to the client.
Use a Disconnect-Request packet to make the client disconnect.
1: Is it possible to send a CoA request to the freeRadius server and then have it relay the request to the Aruba controller?
Yes. This is called "proxying"
2: If it is possible what do I have to put in the configs file and where?
This is documented. Alan DeKok.
