Home > VoIP > STUN Configuration

Simple Traversal of UDP over NAT (STUN) − is a protocol which enables a VoIP device, such as this router or an IP phone, to detect the presence and type of NAT behind which the phone is placed. This router supports STUN and can intelligently modify the private IP address and port in its SIP/SDP message by using the NAT mapped public IP address and port through a series of STUN queries against a STUN server located on the public Internet. This will allow SIP signaling and RTP media to successfully traverse a NAT without requiring any configuration changes on the NAT.

STUN is useful if you need to use the DVG-1402S behind a modem or router that provides the connection to your ISP and then to the Internet and does not support symetric NAT. You will need access to a STUN server on the Internet and its IP address to use STUN on the DVG-1402S.

STUN State

Use this drop-down menu to Enable or Disable STUN on the

 

router.

STUN Server IP Address Enter the IP address of a STUN server in this field.

STUN Server Port

Enter the port number the STUN server will use in this field.

 

If you do not have any information as to the proper port

 

number, leave the default setting here.

STUN ReqInterval

This determines the amount of time, in seconds, between

 

STUN requests. If you do not have any information as to the

 

proper interval, leave the default setting here.

STUN NAT Type

Displays the result of the STUN NAT examination.
