Dynamic DNS

In order to update dns registations when the local IP address changes, a Dynamic DNS service provider can be used. Our os-ddclient plugin offers support for various services using the ddclient software.

Prerequisites

Before installing and using this plugin, make sure to register an account with one of the supported services.

Installation

Installation of this plugin is rather easy, go to System ‣ Firmware ‣ Plugins and search for os-ddclient, use the [+] button to install it.

Next go to Services ‣ Dynamic DNS ‣ Settings to configure one or more Dynamic DNS services.

General settings

The general settings tab offers access to general options used by all configured dynamic dns services on this firewall. By default the service is enabled after installation,

Option	Description
Enable	Enable the client
Interval	The number of seconds address changes will be queried

Accounts

In the primary tab you can register one or more dynamic dns providers which will be used to update dns registrations using an api call over http(s) to the selected service.

Note

The local IP address used for this firewall will be obtained by querying one of the selected providers. Since ddclient currently doesn’t support dual stack (IPv4+IPv6) opertion, make sure to either select an IPv4 or IPV6 address provider in the settings tab.
