From the originate-coa documentation, it seems I can?t originate coa-request at the section of pre-proxy or post-proxy.

It?s documented, pretty clear.

It's nice to hear that the documentation helps. :)

I thought docs are very helpful at most of time. :p

I?m not sure whether it is the cause of my following questions.

It is.

...

But what if I need two steps below finished continually both in the same move:

1. **proxy** auth request to other AAA dispatcher(also FreeRADIUS) to decide where to authenticate.

That's easy.

2. Getting Access-Accept in post-auth, then originate coa request at once in order to change redirect profile to forward profile for subscriber.

That's hard. At least with "originate-coa".

So.. the core concept of *originate-coa* is just "proxy-the-coa" instead of initiating a coa request?

The short answer is that you can run "radclient" as an external program from the post-proxy section. It's ugly, but it will work.

Hmm..that is indeed an alternative, but like you said, it's kind of not a neat way to achieve my goal. And I'm worrying that might have some performance issue if supposed I will have high traffic.

But I got the warning that **cannot proxy and originate CoA packets at the same time**.

Yes. We're looking into fixing that for 3.0.

No offense, I'm curious that why can't view these two request: "Proxy-Auth Request" and "CoA Request" as two independent request? Or this is about some kind of concern on designation? I thought that was intuitive until I saw the result and got your kind but hopeless response : (

Actually I move the coa origination to my AAA dispatcher, it also can?t works and occurs the same warning.(It makes sense because both are doing coa request after proxying auth request I guess.

Originating a CoA packet is really proxying it. And the server can't proxy to two different destinations.

Ok. I got your point.

...

So here are my questions:

1. Does this flow works possibly in my scenario? I mean can I originate coa at once after getting Access-Accept?

Not today.

Does this would be a difficult demand?

...

2. What if I set a **virtual coa server** for receiving coa request from itself, then send to gateway at the section of

That won't change anything.

It may be easy to originate CoA packets *after* proxying. Just so long as it doesn't do both at the same time.

What do you mean *after*? The next any-kind-of request? But I really need they do it in the same sequence. It a bit upset me.

I'll see if I have time to look into it.

Thanks Alan! Thanks your contribution and devotion to FreeRADIUS. It's really impressive. Not a compliment at all. lol
