Click "Services >> DNS >> DNS Relay", check "Enable DNS Relay", set the mapping
between the domain name and the IP address, click Add, and then click Apply &
Save. After the settings are completed, when a DNS client on the LAN requests a
host domain name in the list, the DNS agent server returns the corresponding IP
address to the client.
5.4.3 DDNS
The dynamic domain name server (DDNS) maps the dynamic IP address of the gateway
to a fixed DNS. Each time a user connects to the Internet, the client program
transmits the dynamic IP address of the host to the server program on the server
host through information transfer. The server program provides the DDNS service
and realizes dynamic domain name resolution. In this way, you can access the
Internet by entering the domain name, even if the IP address is changed.
Method for enabling the DDNS service for the gateway:
1. If the Custom service is used, set "Method Name" as required, select "Custom"
for "Service Type", and enter the DDNS expression "http://user
name: password@ddns.oray.com/ph/update?hostname= host name" of the server for "Url".
This expression is only for reference. The actual URL is provided by the service
provider (usually available on the official website of the service provider).
