Disable SureLink

If your device uses a private APN with no Internet access, or your device has a restricted wired WAN connection that doesn't allow DNS resolution, follow this procedure to disable the default SureLink connectivity tests. You can also disable DNS lookup or other internet activity, while retaining the SureLink interface test.


  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 > Interfaces.
  4. Select the appropriate WAN or WWAN on which SureLink should be disabled..
  5. After selecting the WAN or WWAN, click IPv4 > SureLink.

  6. Toggle off Enable to disable SureLink.
  7. 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 IX14 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. Change to the WAN or WWAN's node in the configuration schema. For example, to disable SureLink for the Modem interface:
    (config)> network interface modem
(config network interface modem)>
  4. Disable SureLink:
    (config network interface modem> ipv4 surelink enable false
(config network interface modem)>
  5. Save the configuration and apply the change:
    (config network interface my_wwan ipv4 surelink)> save
Configuration saved.
>
  6. 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.

Disable DNS lookup

Alternatively, you can disable DNS lookup or other internet activity for device that use a private APN with no Internet access, or that have restricted wired WAN connections that do not allow DNS resolution, while retaining the SureLink interface test. The SureLink interface test determines if the interface has an IP address assigned to it, that the physical link is up, and that a route is present to send traffic out of the network interface.


  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 > Interfaces.
  4. Select the appropriate WAN or WWAN on which SureLink should be disabled..
  5. After selecting the WAN or WWAN, click IPv4 > SureLink.

  6. Click to expand Test targets.
  7. Click to expand the second test target. This test target has its Test type set to Test DNS servers configured for this interface.

  8. Click the menu icon (...) next to the target and select Delete.

  9. 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 IX14 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. Change to WAN or WWAN's node in the configuration schema. For example, to disable SureLink for an interface named my_wan:
    (config)> network interface my_wan
(config network interface my_wan)>
  4. Determine the index number of the target:
    (config network interface my_wan)> show ipv4 surelink target
0
	interface_down_time 600s
	interface_timeout 120s
	test interface_up
1
	test dns_configured
(config network interface my_wan)>
  5. Delete the target:
    (config network interface my_wan> del ipv4 surelink target 1
(config network interface my_wan)>
  6. Save the configuration and apply the change:
    (config network interface my_wan ipv4 surelink)> save
Configuration saved.

  7. 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.
