Thanks for the quick reply.
We have APs which located at different locations. APs are behind nat.
Clients authenticated over cloud radius server. But the radius server can
not make CoA requests to APs if there is not firewall rules exist. For some
reason we can not add firewall rules to forward CoA port to APs.
Using the same TLS connection is not a must for us if there exists any
other methods to send CoA requests to APs.
So, can we use freeradius as proxy to achieve this purpose?

No. There is no standard specification for this behaviour. No RADIUS
server *or* NAS supports it.

According to the docs and config files... yes.

Feel free to send patches.
But the larger question is why? And what NAS supports this?
You can add this to FreeRADIUS all you want, but nothing else supports
it. So it's a cute idea, but utterly useless in practice.
