# Traversal Cloud

After enabling the **Traversal Cloud**, you can access and control the 4G routers anytime, anywhere, on a web browser. It offers the easiest way to look over your networks. No public IP address and DDNS configuration are required. **It’s completely free!**

A web proxy is pre-built in the firmware. The traversal cloud is turned off by default. You can follow the below steps to enable it.

1. Log in to the router, go to `Services` > `Traversal Cloud`.
2. Click the checkbox `Enable`, then click the button `Save & Apply`.
3. Now you can access your router at the `Cloud Address` on a web browser.

It is recommended to set up a strong router password (go to `System` > `Administration`) before enabling the traversal cloud.

## Remote SSH <a href="#remote-ssh" id="remote-ssh"></a>

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 into various platforms.

1. Log in to the router, go to `System` > `Administration` and enable the checkbox of `Gateway Ports`. \**You can change the SSH port.*
2. Go to `Service` > `Traversal Cloud`. Click the tab of `Rules`, and click the `Add` button to add an extra SSH proxy.
3. Configure the new proxy using the parameters below.\
   `Proxy Name`Use SSH\_Router-Serial-Number *\*Must be unique!*\
   `Type`: Choose `TCP`\
   `Local IP`: Use `127.0.0.1`\
   `Local Port`: Default `22`. *\* The same as the router SSH port.*\
   `Remote Port`: Adjustable\
   `Privilege Mode`: Must enable this checkbox.
4. Click the `Save & Apply` button.
5. Now, you can access the router via remote SSH on an SSH tool.&#x20;

```
#Example of remote SSH
ssh -oPort=6222 root@ezr33.outdoorrouter.net
```

## Debug <a href="#debug" id="debug"></a>

If unable to access the cloud address, please check the below factors.

1. Please ensure the traversal cloud has been **enabled**. After enabling the checkbox, please click the `Save & Apply` button.
2. Before accessing the traversal cloud server, the router must have an Internet connection. Please check the Internet connection on the router.
3. If you once turned off the traversal cloud function within a power cycle, please reboot the router to refresh the traversal connection session.

&#x20;**\*\*\* REMINDER \*\*\***

The traversal cloud is relayed on the carrier's gateway. Some airlines might block the traversal technology. We do not 100% ensure the cloud address works perfectly. The traversal cloud is provided for free, and it's not involved in the outdoor router quality or working performance.
