Introduction Want to access the Internet safely and securely from your smartphone or laptop when connected to an untrusted network such as the WiFi of a hotel or coffee shop? Open the OpenVPN Port and Enable the Changes Next, we'll adjust the firewall itself to allow traffic to OpenVPN. OpenVPN can be used in a routed or bridged VPN mode and can be configured to use either UDP or TCP. Here is an example SCP command using our client1 example.

The first area of attention will be for the IP address of your Droplet. Two additional queries at the end require a positive y response: Sign the certificate?

Contents - Towards the end, you will have to enter y to two questions to sign and commit the certificate: Output. Now generate the client configuration files including the private key, certificates.

 

This tutorial will keep the installation and configuration steps as simple as possible for these setups. Schritt 1 — Install and Configure OpenVPN's Server Environment Complete these steps for your server-side setup. OpenVPN Configuration Before we install any packages, first we'll update 's repository lists. This tutorial will use Vim but you can use whichever editor you prefer. You will see a section looking like this: Diffie hellman parameters. Generate your own with: openssl dhparam -out dh1024. This can help prevent DNS from leaking outside the VPN connection. Though OpenDNS is the default used by OpenVPN, you can use whichever DNS services you prefer. The last area to change in server. It should look like this when done: user nobody group nogroup Standardmäßig, OpenVPN runs as the Wurzel user and thus has full root access to the system. We'll instead confine OpenVPN to the user nobody and group nogroup. This is an unprivileged user with no default login capabilities, often reserved for running untrusted applications like web-facing servers. Now save your changes and exit Vim. Packet Forwarding Das ist ein sysctl setting which tells the server's kernel to forward traffic from client devices out to the Internet. Andernfalls, the traffic will stop at the server. It should look like this when done: Uncomment the next line to enable packet forwarding for IPv4 net. Uncomplicated Firewall ufw ufw is a front-end for iptables and setting up ufw is not hard. It's included by default in , so we only need to make a few rules and configuration edits, then switch the firewall on. As a reference for more uses for ufw, sehen. First set ufw to allow. In the command prompt, ENTER: ufw allow ssh This tutorial will use OpenVPN over UDP, so ufw must also allow UDP traffic over port 1194. We'll do this in ufw's primary configuration file. This must be changed from FALLEN zu ACCEPT. The area in rot zum OPENVPN RULES must be added: rules. Enter into the command prompt: ufw enable Enabling ufw will return the following prompt: Command may disrupt existing ssh connections. Proceed with operation y n? Configure and Build the Certificate Authority It is now time to set up our own Certificate Authority CA and generate a certificate and key for the OpenVPN server. OpenVPN supports bidirectional based on certificates, meaning that the client must authenticate the server certificate and the server must authenticate the client certificate before mutual trust is established. We will use Easy RSA's scripts we copied earlier to do this. First copy over the Easy-RSA generation scripts. This information is copied to the certificates and keys, and will help identify the keys later. Aus Gründen der Einfachheit, wir werden verwenden server as the key name. If you want to use a different name, you would also need to update the OpenVPN configuration files that reference server. Pay attention to the dot. That signifies the current working directory source. Since we haven't generated anything in the keys directory yet, the warning is nothing to be concerned about. NOTE: If you run. The output will prompt you to confirm the Distinguished Name variables that were entered earlier into the Easy-RSA's variable file country name, Organisation, etc. If something must be changed, you can do that from within the prompt. Two additional queries at the end require a positive y response: Sign the certificate? Let's copy them into the proper location. An diesem Punkt, the OpenVPN server is ready to go. Start it and check the status. Your OpenVPN server is operational. Re-copy the file and try again. Schritt 3 — Generate Certificates and Keys for Clients So far we've installed and configured the OpenVPN server, created a Certificate Authority, and created the server's own certificate and key. In diesem Schritt, we use the server's CA to generate certificates and keys for each client device which will be connecting to the VPN. These files will later be installed onto the client devices such as a laptop or. Key and Certificate Building It's ideal for each client connecting to the VPN to have its own unique certificate and key. This is preferable to generating one general certificate and key to use among all client devices. Hinweis: Standardmäßig, OpenVPN does not allow simultaneous connections to the server from clients using the same certificate and key. To create separate credentials for each device you intend to connect to the VPN, you should complete this step for each device, but change the name client1 below to something different such as client2 oder iphone2. With separate credentials per device, they can later be deactivated at the server individually, if need be. The remaining examples in this tutorial will use client1 as our example client device's name. As we did with the server's key, now we build one for our client1 Beispiel. Drücken Sie ENTER to accept the defaults. We'll use it as a template which will be downloaded to client devices for editing. In the copy process, we are changing the name of the example file from client. For each client we need to transfer the client certificate, Schlüssel, and profile template files to a folder on our local computer or another client device. Download these two files as well; note that the ca. This will transport your client's VPN authentication files over an encrypted connection. Here is an example SCP command using our client1 Beispiel. It places the file client1. This is created by modifying the client. Once merged, only the single client. We will create a single profile for our client1 device on the local computer we downloaded all the client files to. This local computer could itself be an intended client or just a temporary work area to merge the authentication files. How you do this will depend on the operating system of your local computer. Hinweis: The name of your duplicated client. The client-side OpenVPN application will use the file name as an identifier for the VPN connection itself. Stattdessen, you should duplicate client. In diesem Tutorial, we'll name the VPN connection DigitalOcean so DigitalOcean. Once named, we then must open DigitalOcean. The first area of attention will be for the of your Droplet. Near the top of the file, Veränderung my-server-1 to reflect your VPN's IP. You can have multiple remote entries to load balance between the servers. Hinweis: This doesn't apply to Windows so you can skip it. It should look like this when done: Downgrade privileges after initialization non-Windows only user nobody group nogroup The area given below needs the three lines shown to be commented out so we can instead include the certificate and key directly in the DigitalOcean. Schlüssel files are pasted directly into the. The XML at the end of the file should take this form: insert ca. Save the changes and exit. We now have a unified OpenVPN client profile to configure our client1. Schritt 5 - Installing the Client Profile Now we'll discuss installing a client VPN profile on Windows, OS X, iOS, und Android. None of these client instructions are dependent on each other so you can skip to whichever is applicable to you. Remember that the connection will be called whatever you named the.

This also means that standard users will need to enter the administrator's password to use OpenVPN. Andererseits, standard users can't properly connect to the server unless OpenVPN on the client has admin rights, so the elevated privileges are necessary. To set the OpenVPN application to always run as an administrator, right-click on its shortcut icon and go to Eigenschaften. At the bottom of the Kompatibilität Tab, click the button to Change settings for all users. In dem neuen Fenster, prüfen Run this program as an administrator.
