Yeastar FQDN Overview

A Yeastar-supplied Fully Qualified Domain Name (FQDN) helps you to quickly establish a secure remote connection in only one click. It frees you from the risky port forwarding, complicated network setup, and onerous Linkus server configurations. With the private and secure connection, you don't have to worry about exposing your intranet to the public, or NAT issues to happen and affect your remote calling experience.

What is FQDN?

A Fully Qualified Domain Name (FQDN) is the complete domain name for a specific device on the internet. An FQDN consists of two parts: the hostname and the domain name.

Yeastar-supplied FQDN function provides the following advantages:

  • Dynamic DNS solution: Provide a dynamic DNS service for network environments that has no static IP addresses to ensure proper access to the system.
  • Hassle-free network deployment: Simplify network configurations for remote access as the complicated Network Address Translation (NAT) configurations and port forwarding are eliminated.
  • High call quality: Avoid NAT issues that affect call quality, thus guarantee remote calling experience.
  • Secure communication: Eliminate the risk of exposing service ports; secure remote connections with SSL certificates.
