A Virtual Private Network (VPN) allows you to move your internet traffic to a different machine in a different geographical location by creating a private cryptographically protected route to that location. The usual use cases are to get around local censorship of the internet such as when you see the message "<i>this content is not available in your area</i>" when trying to play a video. Maybe you're on holiday and your hotel or workplace internet connection is censored. Using a VPN you can connect to your home server and then use the internet normally.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Using a Tor browser is another way to get around censorship, but there might be occasions where you don't want to use a Tor browser or where Tor relays and bridges are blocked or where you want to run internet apps which aren't within a browser.

Select <b>Administrator controls</b> then <b>Add/Remove apps</b> then <b>vpn</b>. Choose the port which you want the VPN to operate on and then the install will continue.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Only use ports 443 or 80 for VPN as an <i>absolute last resort</i>, since doing so will prevent other web based apps from running on your server.

You will need to ensure that the <i>openvpn</i> and <i>stunnel</i> packages are installed. On an Arch based system:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<div class="org-src-container">
|
||
|
|
<pre class="src src-bash">sudp pacman -S openvpn stunnel4
|
||
|
|
</pre>
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Or on a Debian based system:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<div class="org-src-container">
|
||
|
|
<pre class="src src-bash">sudo apt-get install openvpn stunnel4
|
||
|
|
</pre>
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Now you can connect to your VPN with:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<div class="org-src-container">
|
||
|
|
<pre class="src src-bash">sudo stunnel stunnel-client.conf
|
||
|
|
sudo openvpn client.ovpn

Select <b>Administrator controls</b> then <b>App Settings</b> then <b>vpn</b>. Choose <b>Change TLS port</b> and enter a new port value. You can then either manually change the port within your VPN configuration files, or download them again as described in the <a href="#org1a94be0">Usage</a> section above.

It's possible that your VPN keys might get lost or compromised on your local machine. If that happens you can generate new ones from the <b>Administrator controls</b> by going to <b>App Settings</b> then <b>vpn</b> then choosing <b>Regenerate keys for a user</b> and downloading the new keys as described in the <a href="#org1a94be0">Usage</a> section above.
