It is easy to access and control your outdoor 4G routers 24x7 on a web browser. You don’t need public IP address and DDNS configuration. And it’s free of cost!

Enable the traversal cloud by the following steps.

  • Log in the router admin at Select Services and then Traversal Cloud

The custom Remote SSH is an advanced tool to connect your router remotely via the command-line interface. It offers a flexible solution to integrate your router to various platforms. The customised traversal cloud proxy rule is available for firmware version EV3104 only.
