Freeradius 3.x - CoA proxy and dynamic-client

Hi everyone,

I'm trying to solve a litte issue with my freeradius scenario.

My scenario is like this

Client ----- proxy (FR 3.x) ------ AAA (FR 3.x)

                          |----------------- COA generator (Java)

So, I have a proxy frontend with dynamc-clients virtualserver wich forwards
the authentication and accounting requests to the backend via realm module.
this is working like a charm.

I would like to use also coa requests to the client. this requests are
generated by a java software, then they should be proxied by the frontend
and forwarded to the client.

from my understanding the realm module needs a static client definition to
proxy the coa requests, but this is not applicable to my scenario.

so now I'm trying to find some kind of workaround, but i'm not able to find
any documentation on known pattern on the documentation.

is someone facing the same problem or had solved it in the past?

thank you and best regards!
