What is TURN and STUN?

STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) servers are both used in the signaling process but for different reasons. Before establishing a peer-to-peer connection, it is essential for servers to identify the IP address for each participant.

What is a STUN port?

STUN is a tool for communications protocols to detect and traverse network address translators that are located in the path between two endpoints of communication.

What is TURN port?

Implies if a cruise port is a homeport (turn) port or a call port. A homeport is where a cruise itinerary begins (and ends) and where passengers can embark on a cruise ship for the first time. A call port is where passengers can temporarily disembark for a shore excursion or any other touristic activity.

What is the port range for STUN?

The STUN server uses a single port for client connections (3478 by default), so this port should be opened up for the public in the server's network configuration or Security Group. If using TURN relay, then the whole range of TURN ports (49152 to 65535 by default) should be opened up too, besides the client port.

Is STUN TCP or UDP?

A STUN server allows a computer on the internet to determine its own public-facing IP address. STUN uses UDP, and STUN servers typically listen for UDP requests on port 3478. For a client to use STUN, their network must allow UDP traffic.

Does STUN use TCP?

UDP/TCP/TLS: Typically, STUN uses UDP, TCP or TLS as its transport protocol. The well known UDP/TCP port for STUN traffic is 3478. There is no well known port for TLS.

Why STUN and TURN server is used?

STUN is a network protocol used to retrieve the public IP address (or Transport address) of a device behind NAT so that the device can communicate after knowing its address on the internet. Usually, a STUN server is requested by the peer to know its public IP addresses (or specifically its transport address).

What does a STUN do?

The bright light and loud sound of the stun grenade are designed to surprise and temporarily incapacitate persons in the targeted area to permit an immediate entrance by attack personnel under less dangerous circumstances.

What is STUN protocol used for?

The STUN protocol defined by RFC is used to discover NAT devices located along the path between two communicating parties and to obtain post-NAT IP addresses and port numbers of the communicating parties.

What are the 3 types of port?

Three Styles of Port

Within the three categories of Port wine, Ruby, Tawny and White, there are more than one style, each with their own labeling, so it can be frustrating as a consumer to know and remember all the different kinds.

Does TURN use TCP or UDP?

TURN can use different transport protocols to relay its media: TURN/UDP – relaying media over UDP. This is the preferred method for handling real time media. TURN/TCP – relaying media over TCP.

Why STUN and TURN server is used?

STUN is a network protocol used to retrieve the public IP address (or Transport address) of a device behind NAT so that the device can communicate after knowing its address on the internet. Usually, a STUN server is requested by the peer to know its public IP addresses (or specifically its transport address).

What does a STUN do?

The bright light and loud sound of the stun grenade are designed to surprise and temporarily incapacitate persons in the targeted area to permit an immediate entrance by attack personnel under less dangerous circumstances.

What is STUN TURN and ICE?

What are STUN, TURN, and ICE? STUN, TURN, and ICE are a set of IETF standard protocols for negotiating traversing NATs when establishing peer-to-peer communication sessions. WebRTC and other VoIP stacks implement support for ICE to improve the reliability of IP communications.

Is STUN server necessary?

STUN (Session Traversal Utilities for NAT)

This is needed for them to connect directly. A peer does not know its public IP address since that is handled by NAT and is beyond the knowledge of the peer. This is where the STUN server comes into the picture.

What is signaling vs STUN?

Signaling server is used to let peers share service information to start the peer-to-peer streams transmission. STUN server is used to let peers know each other's external address to start the peer-to-peer streams transmission behind the NAT.
