Example: Configure two LANs

The default configuration of the EX15 consists of one WAN (named ETH1), one WWAN (Modem), and one LAN (ETH2). For EX15W Wi-Fi enabled devices, the default configuration of the ETH2 uses a bridge that consists of two devices, the ETH2 Ethernet device and the Digi AP Wi-Fi access point.

In this example, we will:

  1. Create a new Wi-Fi access point (EX15W models only).
  2. Create a new bridge that consists of the new access point and the ETH1 device.

    In this configuration, the ETH1 device will no longer be part of a WAN. Internet access will be provided by the cellular modem.

  3. Create two new LANs:
    • LAN1 will be configured to use the new bridge.
    • LAN2 will be configured to use the ETH2 device.

Task one: Create a new access point (EX15W models only)


  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.

      The Configuration window is displayed.

  3. Click Network > Wi-Fi > Access points.

  4. For Add Wi-Fi access point, type Example_AP for the name of the new access point and click .

    The Wi-Fi access point configuration window is displayed.

  5. For SSID, type Example_SSID.
  6. Type a Pre-shared key that clients will use to access the AP.

  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 EX15 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. Create a new access point:
    (config)> add network wifi ap Example_AP

    New access points are enabled by default.

  4. Set the SSID for the Wi-Fi access point. Up to 32 characters are allowed.
    (config network wifi ap Example_AP)> ssid Example_SSID
(config network wifi ap Example_AP)>

    SSID broadcasting is enabled by default for new access points.

  5. Set the security for the access point to WPA2:
    (config network wifi ap Example_AP)> encryption type wpa2
(config network wifi ap Example_AP)>
  6. Set the password that clients will use when connecting to the access point:
    (config network wifi ap Example_AP)> encryption key_psk2 password
(config network wifi ap Example_AP)>
  7. Save the configuration and apply the change.
    (config network wireless ap Example_AP)> save
Configuration saved.
