Configure dynamic DNS

This section describes how to cofigure dynamic DNS on a IX20 device.

Required configuration items

Additional configuration items


  1. Log into Digi Remote Manager, or log into the local Web UI as a user with full Admin access rights.
  2. Access the device configuration:

    1. Locate your device as described in Use Digi Remote Manager to view and manage your device.
    2. Click the Device ID.
    3. Click Settings.
    4. Click to expand Config.

    1. On the menu, click System. Under Configuration, click Device Configuration.

      The Configuration window is displayed.

  3. Click Network > Dynamic DNS.
  4. Type a name for this Dynamic DNS instance in Add Service and click .

    The Dynamic DNS configuration page displays.

    New Dynamic DNS configurations are enabled by default. To disable, toggle off Enable.

  5. For Interface, select the interface that has its IP address registered with the Dynamic DNS provider.
  6. For Service, select the Dynamic DNS provider, or select custom to enter a custom URL for the Dynamic DNS provider.
  7. If custom is selected for Service, type the Custom URL that should be used to update the IP address with the Dynamic DNS provider.
  8. Type the Domain name that is linked to the interface's IP address.
  9. Type the Username and Password used to authenticate with the Dynamic DNS provider.
  10. (Optional) For Check Interval, type the amount of time to wait to check if the interface's IP address needs to be updated.

    Allowed values are any number of weeks, days, hours, minutes, or seconds, and take the format number{w|d|h|m|s}.

    For example, to set Check interval to ten minutes, enter 10m or 600s.

  11. (Optional) For Forced update interval, type the amount of time to wait to force an update of the interface's IP address.

    Allowed values are any number of weeks, days, hours, minutes, or seconds, and take the format number{w|d|h|m|s}.

    For example, to set Forced update interval to ten minutes, enter 10m or 600s.

    The setting for Forced update interval must be larger than the setting for Check Interval.

  12. (Optional) For Retry interval, type the amount of time to wait for an IP address update to succeed before retrying the update.

    Allowed values are any number of weeks, days, hours, minutes, or seconds, and take the format number{w|d|h|m|s}.

    For example, to set Retry interval to ten minutes, enter 10m or 600s.

  13. (Optional) For Retry count, type the number of times to retry a failed IP address update.
  14. Click Apply to save the configuration and apply the change.
  1. Select the device in Remote Manager and click Actions > Open Console, or log into the IX20 local command line as a user with full Admin access rights.

    Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

  2. At the command line, type config to enter configuration mode:

    > config
(config)>

  3. Add a new Dynamic DNS instance. For example, to add an instance named new_ddns_instance:
    (config)> add network ddns new_ddns_instance
(config network ddns new_ddns_instance)>

    New Dynamic DNS instances are enabled by default. To disable:

    (config network ddns new_ddns_instance)> enable false
(config network ddns new_ddns_instance)>

  4. Set the interface for the Dynamic DNS instance:
    1. (config network ddns new_ddns_instance)> interface ?

Interface: The network interface from which to obtain the IP address to register with the dynamic DNS service.
Format:
  setupip
  setuplinklocalip
  eth1
  eth2
  loopback
Current value: 

(config network ddns new_ddns_instance)> interface
    2. Set the interface. For example:
      (config network ddns new_ddns_instance)> interface eth1
(config network ddns new_ddns_instance)>
  5. Set the Dynamic DNS provider service:
    1. (config network ddns new_ddns_instance)> service ?

Service: The provider of the dynamic DNS service.
Format:
  custom
  3322.org
  changeip.com
  ddns.com.br
  dnsdynamic.org
  ...

Default value: custom
Current value: custom

(config network ddns new_ddns_instance)> service
    2. Set the service:
      (config network ddns new_ddns_instance)> service service_name
(config network ddns new_ddns_instance)>
  6. If custom is configured for service, set the custom URL that should be used to update the IP address with the Dynamic DNS provider:
    (config network ddns new_ddns_instance)> custom url
(config network ddns new_ddns_instance)>
  7. Set the domain name that is linked to the interface's IP address:
    (config network ddns new_ddns_instance)> domain domain_name
(config network ddns new_ddns_instance)>
  8. Set the username to authenticate with the Dynamic DNS provider:
    (config network ddns new_ddns_instance)> username name
(config network ddns new_ddns_instance)>
  9. Set the password to authenticate with the Dynamic DNS provider:
    (config network ddns new_ddns_instance)> password pwd
(config network ddns new_ddns_instance)> 
  10. (config network ddns new_ddns_instance)> check_interval value
(config network ddns new_ddns_instance)>

    where value is any number of weeks, days, hours, minutes, or seconds, and takes the format number{w|d|h|m|s}.

    For example, to set check_interval to ten minutes, enter either 10m or 600s:

    (config network ddns new_ddns_instance)> check_interval 600s
(config network ddns new_ddns_instance)>

    The default is 10m.

  11. (config network ddns new_ddns_instance)> force_interval value
(config network ddns new_ddns_instance)>

    where value is any number of weeks, days, hours, minutes, or seconds, and takes the format number{w|d|h|m|s}.

    For example, to set force_interval to ten minutes, enter either 10m or 600s:

    (config network ddns new_ddns_instance)> force_interval 600s
(config network ddns new_ddns_instance)>

    The default is 3d.

  12. (config network ddns new_ddns_instance)> retry_interval value
(config network ddns new_ddns_instance)>

    where value is any number of weeks, days, hours, minutes, or seconds, and takes the format number{w|d|h|m|s}.

    For example, to set retry_interval to ten minutes, enter either 10m or 600s:

    (config network ddns new_ddns_instance)> retry_interval 600s
(config network ddns new_ddns_instance)>

    The default is 60s.

  13. (config network ddns new_ddns_instance)> retry_count value
(config network ddns new_ddns_instance)>

    where value is any interger. The default is 5.

  14. Save the configuration and apply the change.
    (config)> save
Configuration saved.
>
  15. Type exit to exit the Admin CLI.

    Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.
