Configure Network for Remote Access by a Yeastar FQDN

A Yeastar-supplied Fully Qualified Domain Name (FQDN) frees you from complicated network settings and helps you quickly establish a secure tunnel for remote access. You can create a Yeastar FQDN in the PBX to allow remote access within seconds.

Background information

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 has the following advantages and limitations.

  • For the network environment that has no static public IP address, a Yeastar-supplied FQDN implements a dynamic DNS service for you.
  • Simplify network configurations for remote access as the complicated Network Address Translation (NAT) configurations and port forwarding are eliminated.
  • Secure remote connections with SSL certificates.
Yeastar FQDN is only for Linkus remote access and web remote access.

  2. Turn on Yeastar FQDN.
  3. In the Fully Qualified Domain Name (FQDN) field, select a domain name then enter a hostname.

    For example, select domain name and enter hostname yeastardocs, you will get an FQDN

    Note: Think twice before you enter the hostname. The FQDN cannot be changed after you save the configurations.
