Configuration Example for Dynamic DNS
4.1 Network Requirement
Host A gets internet services from an ISP (Internet Service Provider) via a PPPoE dial-up
connection. The user wants to visit the router’s web management interface using another
host on the internet.

Internet Host Host A Router
4.2 Configuration Scheme
For security management, the internet hosts attempting to manage the router must be
permitted by the router. Remote Management is used to manage the IP addresses of these
hosts.
Because the user uses PPPoE to access the network, the public IP address of the router
may be changed each time the dial-up connection is established. When the public IP
address of the router changes, DDNS service ensures the DNS server rebinds the current
domain name to the new IP address. This means the user can always reach the router using
the same domain name, even if the public IP address has been changed.
4.3 Configuration Procedure
4.3.1 Specifying the IP Address of the Host
Before configuring DDNS, it is required to specify the IP address of the internet host
for remote management. For details, go to System Tools > Admin Setup > Remote
Management page.
4.3.2 Configuring the DDNS function
There are four DDNS servers supported by the router, we take Peanuthull DNS as an
example here.
1) Choose the menu
Services > Dynamic DNS > Peanuthull and click Add to load the
following page. Click Go to register to register a domain name on the official website of
Peanuthull.
