Configuring VidyoRouter NAT Firewall Settings


This page is used for traversal of a NAT when the VidyoPortal and VidyoRouter are hosted behind a NAT. For more information, see the Firewall and Network Address Translations (NAT) Deployments section.


To configure VidyoRouter NAT Firewall settings:

  1. Log in to the Super Admin portal using your Super Admin account.

    For more information, see Logging in to the Super Admin Portal.

    The Components page displays by default.

  2. Double-click on the blue link in the Name column for the VidyoRouter component.

    The VidyoRouter pop-up displays.

  3. Enter the following information:

    The Media Address Map feature is the preferred configuration option. Only enter values for NAT Firewall fields or Media Address Map fields. Enabling both options and by entering values for each causes the system to malfunction.

    • Enter an IP and port of a STUN server in the NAT Firewall fields.

      A STUN server generally uses port 3478.

      If the system is NATed without a 1:1 port mapping, you must configure the VidyoRouter to use a STUN server residing on the WAN side for network traversal.

    • Enter an IP and port in the Media Address Map fields.

      If the system is NATed with a 1:1 port mapping, hence no port translation, you can define local <-> public address mappings.

      The remote IP address is the IP address that the system is NATed to from the side that users connect from.

    • Select the Media Port Range checkbox and provide Start and End port numbers.

      If only one port is available, enter the same port number in each Start and End field.

      This allows you to define a range of ports available in your firewall.
