It is possible to create a network of LTE routers?

Hardware Questions and Recommendations
1

Hello , my name is Francisco Zuñiga, We are installing CPE routers that use LTE network, we have 10 sites with these routers and we would like to know if it is possible to access them from internet in order to check how is the performance of the router.

The routers are the Ex-Link HOR101 that use OpenWrt.

I´ll appreciate any advise.

Thanks

Hi,

I've not found that device in the table of hardware, what version of Openwrt is it claimed to use?

Hi, the specs of the equipment is as follows:

Model : openwrt
Architecture: MediaTek MT7628AN ver:1 eco:2
Firmware Version: 1.8
Kernel Version : 4.14.195

Best regard

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.

Hi Francisco,

You may do DDNS if you are receiving public IPs.
If not - you must build some sort of VPN via something with known static IP or a domain name.
In both cases you may need some additional packages, so they must be obtained via the repository of the vendor, if not official OpenWrt. The setup process may differ from the standard one. So you may go to the vendor's webpage and to check if supported.

:warning:This device is claimed to have "Remote management cloud platform" - you may ask the vendor if there is a non-chinase version of this tool. If not - consider migrating to a clean (official) OpenWrt or repacing the devices, since the remote management represents an attack vector which could be easily exploited by the supplier or a third party.

Check, whether "wireguard" (VPN) usable/installable on your device. In case, it is, you should be able to connect all devices to a "relay server" on the web, having public IP. Using this relay (which can be a small VPS), then you can access all devices from remote.
