How to Configure GL.iNet GL-X300B/Collie with Simbase

The GL.iNet GL-X300B, also known as the Collie, is a compact 4G LTE router. This guide covers hardware setup, connecting to the router, setting the APN, and optionally enabling remote access.

Firmware requirements Use the latest GL.iNet router firmware. Older firmware versions have different menu steps.

Before you start, make sure your SIM is activated in the Simbase dashboard. If it isn't, see SIM state first.

Step 1: Prepare the hardware

  1. Press the SIM holder release button with the included needle and remove the SIM tray

  2. Insert your Simbase SIM into the tray, chip facing upwards, and slide it back into the router

  3. Connect the antennas to their labeled connectors

  4. Connect the power cable to the router and plug it into an outlet

RememberThe modem only detects the SIM at boot. If you inserted it while the router was powered on, power-cycle the router before moving on.

Step 2: Connect to the router

The router takes a few minutes after power-on for its Wi-Fi network to appear. The Wi-Fi name (SSID) starts with GL-X300B, and the password is goodlife.

  1. Connect your computer to the router's Wi-Fi, or connect via an Ethernet cable to the LAN port

  2. Open a browser and go to 192.168.8.1

  3. Choose your preferred language and set an admin password

For a visual walkthrough of this step, see GL.iNet's initial configuration guide.

Step 3: Set the APN

  1. In the left-hand menu, click INTERNET

  2. Under Cellular, click Manual Setup

  3. Click More

  4. Clear the APN field and enter simbase (most profiles use simbase; check Set up the APN for the APN specific to your use case and SIM profile)

  5. Optionally, set the MTU value to 1200

  6. Click Apply

Your device should now connect to the internet.

For background on what an APN does and how Simbase's APN profiles work, see Set up the APN.

Enable remote access (optional)

If you need to reach the router's admin panel without being on its local network, you have two options: forwarding a port, or using GL.iNet's GoodCloud platform.

For a visual walkthrough of remote access, see GL.iNet's remote access tutorial.

Option A: Forward a port

Port 80 is unencryptedOpening port 80 makes the router's admin panel reachable over plain HTTP by anything that can reach the IP. On a public IP that includes automated scanners. If you don't need direct access, use GoodCloud instead, or reach the router over a private network.
  1. Make sure your SIM has a public or private IP assigned. See Public IPs

  2. While connected to the router's Wi-Fi or LAN, go to 192.168.8.1 and log in

  3. Click Firewall, then Open Ports on Router

  4. Enter:

    • Name: HTTP

    • Port: 80

    • Protocol: TCP

    • Status: Enabled

  5. Click Add

The router's admin panel is now reachable on its public or private IP.


Option B: Use GoodCloud

  1. Go to ApplicationsRemote Access

  2. Enable GoodCloud, then Remote Web and/or Remote SSH as needed

  3. Select your preferred platform zone

  4. Copy the Device ID

  5. Agree to the Terms & Conditions and click Apply

  6. Log in to GoodCloud

  7. Go to Device List and click + Add device

  8. Paste the copied Device ID, click the refresh button, and select your device

  9. Give the device a friendly name and click Add Device

Your router is now connected to GoodCloud and can be managed remotely from there.

Common questions

It depends on your SIM profile and specific use case. Most use simbase, but other APNs are available. Check Set up the APN for your profile before you configure the router.

Port forwarding needs a public or private IP and exposes the admin panel over plain HTTP. GoodCloud works through GL.iNet's platform whatever your network setup, and is usually the simpler and safer choice.

A lower MTU avoids fragmentation on cellular networks, which can otherwise cause slow or stalled connections. Leave it alone unless you see those symptoms, then try 1200.
