- Ensure the correct network interface:
- The cloud node should be connected to the correct Ethernet interface of your physical machine that is part of the same network as your MikroTik device (which you're trying to access with Winbox).
- Check local machine's firewall settings:
- Sometimes, the firewall on your Windows or other OS may block Winbox neighbor discovery traffic. Ensure Winbox traffic is allowed through the firewall.
- Verify Winbox neighbor discovery:
- Ensure that your Winbox neighbor discovery settings are enabled on your MikroTik device.
- Bridge connections if necessary:
- If your GNS3 setup involves virtual devices and they need to communicate with real devices, make sure to bridge the correct network interfaces between GNS3 and your physical network.
