BeamOS – Dynamic DNS

BEAM OS Logo

Summary

Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS). This is most often utilized when the end-user has a dynamic IP address and wants to bind it to a static hostname.

The router is compatible with many different third-party DNS services that provide the possibility to create a custom hostname and bind it to an IP address. The DDNS service periodically updates the IP address information of the hostname, making sure that the device remains reachable via the same hostname even in cases when its IP address has changed.

This chapter is an overview of the Dynamic DNS section for BEAM routers.

Dynamic DNS Overview

By default, an unconfigured DDNS instance will be present in the Dynamic DNS Overview page (the figure below is an example of this). You can create more DDNS instances by entering a New configuration name and clicking the Add new button or you can edit the existing instance since it is not operational by default.

Editing a DDNS instance

To configure a DDNS instance, click the Edit button located next to it.

The figure below is an example of the edit page of the default DDNS instance called “MyDDNS” (already present in the router by default) and the table below provides information on the configuration fields contained in that page:

yes | no; Default: no
Use IPv6 for this configuration
Status
string; Default: N/A
Data on the last status update of the DDNS instance. When status is shown as “N/A”, it means that the router has not been able to establish a connection to the DNS service provider
Service
third party DNS service (chosen from list*) | — custom –; Default: dyn.com
Third-party DNS service provider
Lookup host
host; Default: yourhost.example.com
Fully qualified domain name (FQDN) of your defined host. This is required to verify what the hostname’s current IP address at DNS is (using nslookup/host command)
Hostname
host; Default: yourhost.example.com
Hostname that will be linked with the router’s IP address
Username
string; Default: your_username
Username required to login to the third party DNS service; used to periodically login to your DNS service account and make necessary updates.
Password
string; Default: your_password
Password required to login to the third party DNS service; used to periodically login to your DNS service account and make necessary updates.
IP address source
Custom | Public | Private | Script; Default: Custom
Defines the source to read the system’s IPv4-Address from, that will be sent to the DNS provider. So if, for example, your RUT has a Private IP (i.e., 10.140.56.57) on its WAN interface, then you can send this exact IP to DDNS server by selecting Private
Network
LAN | WAN | WAN2 | WAN3 | PPP | PPP_USB; Default: WAN
Specifies which interface’s IP address should be bound to the hostname
IP renew interval
integer [5..600000]; Default: 10
Frequency at which the device will check whether it’s IP address has changed
Force IP renew
integer [5..600000]; Default: 72
Frequency at which IP update requests are sent to the DNS provider
