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:

Field NameValueDescription
Enableyes | no; Default: noTurns the DDNS instance ON or OFF
Use HTTP Secureyes | no; Default: noEnables SSL data encryption
Use IPv6yes | no; Default: noUse IPv6 for this configuration
Statusstring; Default: N/AData 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
Servicethird party DNS service (chosen from list*) | — custom –; Default: dyn.comThird-party DNS service provider
Lookup hosthost; Default: yourhost.example.comFully 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)
Hostnamehost; Default: yourhost.example.comHostname that will be linked with the router’s IP address
Usernamestring; Default: your_usernameUsername required to login to the third party DNS service; used to periodically login to your DNS service account and make necessary updates.
Passwordstring; Default: your_passwordPassword required to login to the third party DNS service; used to periodically login to your DNS service account and make necessary updates.
IP address sourceCustom | Public | Private | Script; Default: CustomDefines 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
NetworkLAN | WAN | WAN2 | WAN3 | PPP | PPP_USB; Default: WANSpecifies which interface’s IP address should be bound to the hostname
IP renew interval integer [5..600000]; Default: 10Frequency at which the device will check whether it’s IP address has changed
Force IP renewinteger [5..600000]; Default: 72Frequency at which IP update requests are sent to the DNS provider
