# Web Server

### Prerequisites

Before continuing, make sure that the following steps have been completed:

* NoPorts has been installed on both machines.
* Your NoPorts atSigns are activated, and the associated keys are saved locally.

If you haven’t completed these steps, follow the appropriate installation guide on the [Installation Instructions](https://docs.noports.com/installation) page, then return here once finished.

### Command Line

Here, we demonstrate how to use the NoPorts Tunnel to bridge a web server on a remote machine to localhost:80 so we can access the web server locally.

{% hint style="info" %}
We are assuming that the web server is running on port `8080`, you can replace it with the port that your web server is running on. (Also works over TLS with port 443)
{% endhint %}

\
The command should look like:

```
npt -f @<client> -t @<device> -d <device name> -r @<relay> -p 8080 -l 80
```

Example:

```
npt -f @alice_client -t @alice_device -d my_server -r @rv_am -p 8080 -l 80
```

Now you can access localhost:80 in your browser to access the web server locally.

### Desktop Application

When using the NoPorts desktop application, your connection profile should look something like this:

|                   |                          |
| ----------------- | ------------------------ |
| **Profile Name**  | My Web Server Connection |
| **Device atSign** | @alice\_device           |
| **Device Name**   | my\_server               |
| **Relay**         | @rv\_am                  |
| **Local Port**    | 8880                     |
| **Local Host**    | localhost                |
| **Remote Host**   |                          |
| **Remote Port**   | 8080                     |
