CoA Over TLS (radsec) Support

Hi, Radius clients who are behind NAT can successfully initiate traffic to radius server over freeradius proxy. Can radius server initiate traffic for CoA requests to clients which are behind NAT over freeradius (via already established TLS connection with the clients) ? Does freeradius support CoA-Requests over tls? (RFC 3576 - RFC 5176) I have found a similar question which sent to mail list at 2014. ( http://lists.freeradius.org/pipermail/freeradius-users/2014-June/072715.html ) Can i learn if it is not supported still? Thanks for replies.
