# Expose NAT server

## Test the server

One of the best options is to use a SSH jump host server. For example, you can use serveo.net to test.

In your proxy server, run:

```bash
/usr/bin/ssh -R 35854:localhost:3128 serveo.net
```

In your client, run:

```bash
export http_proxy="http://USER:PASSWORD@serveo.net:35854"
export https_proxy="http://USER:PASSWORD@serveo.net:35854"
export ftp_proxy="http://USER:PASSWORD@serveo.net:35854"
export no_proxy="localhost,127.0.0.1,::1"
curl http://www.google.com
```

### Setup serveo.net as a service

Make sure systemd is installed:

```
apt update
apt install systemd
```

Create the service file:

```bash
nano /etc/systemd/system/serveo-proxy.service
```

With the following content:

```
[Unit]
Description=Serveo proxy tunnel
After=network-online.target

[Service]
User=root
ExecStart=/usr/bin/ssh -R 35854:localhost:3128 serveo.net
RestartSec=3
Restart=always

[Install]
WantedBy=multi-user.target
```

Start and enable the service:

```
sudo systemctl daemon-reload
sudo systemctl enable serveo-proxy.service
sudo systemctl start serveo-proxy.service
```
