TURN client passing Message-Integrity back to the STUN/TURN server After the Message-Integrity attribute has been successfully negotiated, the A/V Edge service STUN/TURN server responds to the remote client with an Allocate Response packet as shown in Figure 5. This packet provides the remote client with the information that it needs to

Jul 21, 2014 · If a STUN server cannot establish the connection, ICE can turn to TURN (pardon the pun). Traversal Using Relay NAT (TURN) is an extension to STUN that allows media traversal over a NAT that does not do the “consistent hole punch” required by STUN traffic. TURN servers are often used in the case of a symmetric NAT. Dec 28, 2017 · Running Wireshark we can see that the STUN-requests are being sent to the private IP-address of the other participant. So if I (external) got the private IP and an internal User I'm trying to call got my client will try to send the STUN to the private IP, which will obviously not work. We are going to install coturn package which is a free open-source implementation of TURN and STUN Server. sudo apt-get -y update sudo apt-get install coturn step3 — Start the coturn Daemon at Mar 05, 2018 · The default ports for your STUN and TURN servers (you’re most probably going to deploy them in the same process) are: 3478 for STUN (over UDP) 3478 for TURN over UDP – same as STUN; 3478 for TURN over TCP – same as STUN and as TURN over UDP; 5349 for TURN over TLS; A few things that come to mind from this list above:

STUN and TURN servers¶. If Kurento Media Server, its Application Server, or any of the clients are located behind a NAT, you need to use a STUN or a TURN server in order to achieve NAT traversal.In most cases, STUN is effective in addressing the NAT issue with most consumer network devices (routers).

The STUN protocol is defined in RFC 3489. The STUN server is contacted on UDP port 3478, however, the server will hint clients to perform tests on alternate IP and port number too (STUN servers have two IP addresses). The RFC states that this port and IP are arbitrary. Stun functionality is seamlessly handled by 3CX – an easy to install PBX.

TURN Server. Traversal Using Relays around NAT (TURN) is a protocol that assists in traversal of network address translators (NAT) or firewalls for multimedia applications. . It may be used with the Transmission Control Protocol (TCP) and User Datagram Protocol (UD
