Configure Dynamic Domain Name Server on RV320 and RV325 VPN Router Series

Objective

Dynamic Domain Name System (DDNS) is a network service that allows a networked device using communication protocols (e.g., a router) to let the Domain Name System (DNS) know that it needs to change its active DNS configuration. It allows routers with different IP addresses to be located by the same Internet domain name. The benefit of using the DDNS is that it assigns fixed host and domain names to a dynamic Internet IP address. DDNS is useful if you want to host a website, FTP server, or other server behind the router.

The objective of this document is to explain how to configure DDNS services, which are offered by the DDNS service providers DynDNS.org and 3322.org.

Note: Before you use any of these features, it is necessary to sign up for DDNS services at DynDNS.org or 3322.org. The router notifies changes in the WAN IP address to the dynamic DNS servers so any public services on the network can access it through the static domain name.
