I have a few questions since it’s not really clear what are the circumstances of your setup.
Do you have a public IP address?
Does your RUT240 have a dynamic IP, if yes, you would need to set up DDNS on your router, since it’s public IP is changing.
Do you have a static lease set for your LAN device, so that is has the same IP address all the time?
Do you have port forward set up in the routers firewall? If not, then try to set up a rule in WebUI -> Network -> Firewall -> Port forwards, then in the opened window:
- Enter the any name;
- For External port enter 8096;
- For internal IP address select your device‘s IP address;
- For internal port enter 8096;
- Click the ADD button;
- When a window opens, just clock SAVE & APPLY at the bottom to save the configuration;
Try to see if this resolved your issue.
If the issue persist, could you send us the troubleshoot file? The files attached are only seen for Teltonika Networks engineers. You can download the file from WebUI System -> Administration -> Troubleshoot and then download the troubleshoot file.
Also, could you provide the network topology of your solution with IP addresses, subnet masks and ports.
