Enabling UDP-CR Forwarding with Coturn STUN Server

[gzm2015]

When my Customer Premise Equipment (CPE) obtains its external IP and port through the STUN server（x.x.x.x:3478), it sends this information to my Auto-Configuration Server (ACS).
When my ACS wants to initiate communication with the CPE, it sends a UDP Connection Request (UDP-CR) to the STUN server. The STUN server（x.x.x.x:3478) then forwards this UDP-CR to my CPE.
Upon receiving the UDP-CR, the CPE initiates a TCP connection with my ACS.

Now, I'm wondering if coturn has any features or methods to help forward this UDP-CR for me.

Hi @gzm2015
I'm not sure I fully understand your setup of what you are trying to achieve but it looks like coturn does not support what you want.
However, you could probably build that yourself by watching created allocations in redis or from logs and then forward them yourself.
