Dynamic DNS Setup
7.1 Introduction
Before you set up the Dynamic DNS (Domain Name Server) function, you
have to subscribe free domain names from the Dynamic DNS service
providers. The Vigor router provides up to three accounts for the function
and supports the following providers: www.dynsns.org,
www.dynamic-nameserver.com, www.no-ip.com, www.dtdns.com,
www.changeip.com. You should visit their websites to register your own
domain name for the router.
The Dynamic DNS function allows the router to update its online WAN IP
address which assigned by ISP to the specified Dynamic DNS server. Once
the router is online, you will be able to use the registered domain name to
access the router or internal virtual servers from the Internet. Use the
following setup link on the Setup Main Menu to configure the Dynamic DNS
Setup function.
