Method for enabling DNS forwarding for the gateway:
As a DNS agent, the gateway forwards DNS request and response messages between the DNS client
and the DNS server, and replaces the DNS client for domain name resolution.
If the DHCP service is enabled for the gateway, DNS forwarding is enabled by default and
cannot be disabled.
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.
