EyeLink is a data viewer integration messaging protocol that allows you to view, filter, and process gaze data that has been recorded with EyeLink eye trackers.

If you want to track and view data through EyeLink, you might need to route some ports through your router. Routing ports allow internet connection requests to come through EyeLink.

Since routers usually don’t allow outside connection requests, routing a port can fix this problem.

Just before you begin with the process of port forwarding, make sure you have the following things:

  • Downloaded and installed the Eyelink server.
  • The IP address of your router.
  • IP address of your device.

TCP and UDP ports of Eyelink are mentioned in the section below.

Now that you have the above details noted down, you can move to the next stage of Eyelink port forwarding:

  1. On your web browser address bar, type your router’s IP Address/Default Gateway.
  2. Log in with your router’s credentials (username and password) to view your router’s firmware settings.
  3. Navigate to the port forwarding section of your router.
  4. Click on Port Forwarding.
  5. Enter the IP address of your device in your router in the correct box.
  6. Put the TCP and UDP ports of the Eyelink server in the boxes in your router. The default Eyelink port number is 589. And then click the apply button.
  7. And you’re done. Restart your router to let the changes take effect.
  8. Once your changes take effect, now you can host a Eyelink server and let your friends connect to it as well. To let them connect to it, you need to provide them the hostname you are using, along with the port number. For example, ‘hostname.domain.com:25565’.
