How To Configure Dynamic DNS for a particular Interface

10/14/2021 205 20892

DESCRIPTION:

This is an enhancement for DDNS.Dynamic DNS is a method, protocol, or network service that provides the capability for a networked device, such as a router or computer system using the Internet Protocol Suite, to notify a domain name server to change, in real time (ad-hoc) the active DNS configuration of its configured hostnames, addresses or other information stored in DNS. Currently, SonicOS supports three DDNS providers, dyn.com , changeip.com and NO-IP. com. Throughout this document, dyn.com is given as an example, but is also applicable to the other providers. DDNS provider will detect your IP based on your wan interface IP, so you have no control on what IP you want to register to the provider.

RESOLUTION:

   • Let the server detect IP Address- The dynamic DNS provider determines the IP address based upon the source address of the connection.This is the most common setting.
   • Automatically set IP Address to the Primary WAN Interface IP Address - This will cause the SonicWall device to assert its WAN IP address as the registered IP address, overriding auto-detection by he dynamic DNS server.
   • Specify IP Address manually - Allows for the IP address to be registered to be manually specified and asserted.
     
     The Off-line Settings section controls what IP address is registered with the dynamic DNS service provider if the dynamic DNS entry is taken off-line locally (disabled) on the SonicWall.The options are:   
     
     
   • Do nothing - the default setting. This allows the previously registered address to remain current with the dynamic DNS provider. This is the most common setting.
