DNS Configuration Using the Web UI

This section describes how to configure DNS and DDNS on the web UI.

For details about the configuration of the DNS transparent proxy and smart DNS function, see Intelligent Uplink Selection.

Configuring DNS

After you specify a DNS server address on a device, the device can serve as a DNS client or DNS proxy agent to send domain name resolution requests to a specific DNS server.

Configuring DDNS

When a FW serves as a DDNS client, a DNS server dynamically updates the mapping between domain names and IPv4 addresses after being notified by a DDNS service provider. This process ensures that domain names are resolved into correct IPv4 addresses.
