Home Questions Tags Users Unanswered. I know there are many tutorials on the net for setting up VPN client and server. I am using an EC2 micro instance running Ubuntu Braiam 50k 20 PPTP is not secure anymore.

Now test it with your OS X client. I'm also wondering which localip and remoteip values are the safest, considering that I'm going to connect to this server from any location. Definetly the default values with Using interface ppp0 May 12 Modem hangup May 12 It doesn't work yet! Yeah this does not work. SorinSbarnea those ips are private and never go over the internet, so I don't know what you mean by "safest".

You'll have best luck if they aren't the same IP range as the cafe, or workplace from which you are connecting. To summarize the main points in the link, though: Open the ports needed. The guide suggests 22 SSH and for the pptp vpn. This example uses OpenDNS servers: Run this command in terminal: Now what the heck do I do: This question only covers setting up the VPN, and the server side.

NOT the connecting to it part. D super fast response: D I think I may have worked it out, I must have just set something incorrectly. This said ufw is active and allowing most ports. Jamie I can give you iptables commands to use when I get home of you prefer iptables to ufw. And the configuration I use is here: Does this method also work on Ubuntu Doesn't work, Ubuntu server Client stuck looking for DNS. Make sure you have the en0 interface and it's not named something else.

You should see a public IP address listed. Then in the Ubuntu network manager the client would list Nick Woodhams 5 6. We need to start the OpenVPN server by specifying our configuration file name as an instance variable after the systemd unit file name. Since our client configuration files will have the client keys embedded, we should lock down permissions on our inner directory:. Next, let's copy an example client configuration into our directory to use as our base configuration:.

First, locate the remote directive. This points the client to our OpenVPN server address. If you changed the port that the OpenVPN server is listening on, change to the port you selected:.

Next, uncomment the user and group directives by removing the " ; ":. Find the directives that set the ca , cert , and key. Comment out these directives since we will be adding the certs and keys within the file itself:.

Next, add the key-direction directive somewhere in the file. This must be set to "1" to work with the server:. Finally, add a few commented out lines. This script uses the resolvconf utility to update DNS information for Linux clients. Next, we will create a simple script to compile our base configuration with the relevant certificate, key, and encryption files.

If you followed along with the guide, you created a client certificate and key called client1. If everything went well, we should have a client1. We need to transfer the client configuration file to the relevant device. For instance, this could be your local computer or a mobile device.

While the exact applications used to accomplish this transfer will depend on your choice and device's operating system, you want the application to use SFTP SSH file transfer protocol or SCP Secure Copy on the backend. This will transport your client's VPN authentication files over an encrypted connection. Here is an example SFTP command using our client1. This command can be run from your local computer OS X or Linux. Here are several tools and tutorials for securely transferring files from the server to a local computer:.

None of these client instructions are dependent on one another, so feel free to skip to whichever is applicable to you. The OpenVPN connection will be called whatever you named the. In our example, this means that the connection will be called client1. Choose the appropriate installer version for your version of Windows. Note OpenVPN needs administrative privileges to install.

OpenVPN must be run as an administrator each time it's used, even by administrative accounts. To do this without having to right-click and select Run as administrator every time you use the VPN, you can preset this, but this must be done from an administrative account.

This also means that standard users will need to enter the administrator's password to use OpenVPN. On the other hand, standard users can't properly connect to the server unless the OpenVPN application 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 Properties. At the bottom of the Compatibility tab, click the button to Change settings for all users.

In the new window, check Run this program as an administrator. Launching the OpenVPN client application only puts the applet in the system tray so that the VPN can be connected and disconnected as needed; it does not actually make the VPN connection. This opens the context menu. Select client1 at the top of the menu that's our client1. A status window will open showing the log output while the connection is established, and a message will show once the client is connected. Disconnect from the VPN the same way: Go into the system tray applet, right-click the OpenVPN applet icon, select the client profile and click Disconnect.

You can download the latest disk image from the Tunnelblick Downloads page. Towards the end of the installation process, Tunnelblick will ask if you have any configuration files. It can be easier to answer No and let Tunnelblick finish.

Open a Finder window and double-click client1. Tunnelblick will install the client profile. Administrative privileges are required. Launch Tunnelblick by double-clicking Tunnelblick in the Applications folder.

Once Tunnelblick has been launched, there will be a Tunnelblick icon in the menu bar at the top right of the screen for controlling connections. Click on the icon, and then the Connect menu item to initiate the VPN connection. Select the client1 connection.

If you are using Linux, there are a variety of tools that you can use depending on your distribution. Your desktop environment or window manager might also include connection utilities. Uncomment the three lines we placed in to adjust the DNS settings if you were able to find an update-resolv-conf file:. If you are using CentOS, change the group from nogroup to nobody to match the distribution's available groups:. Now, you can connect to the VPN by just pointing the openvpn command to the client configuration file:.

To transfer your iOS client configuration onto the device, connect it directly to a computer. Completing the transfer with iTunes will be outlined here. There will be a notification that a new profile is ready to import. Tap the green plus sign to import it.

OpenVPN is now ready to use with the new profile. Start the connection by sliding the Connect button to the On position. Disconnect by sliding the same button to Off. If you try, you will receive a notice to only connect using the OpenVPN app. Open the Google Play Store. Alternatively, if you have an SD card reader, you can remove the device's SD card, copy the profile onto it and then insert the card back into the Android device. The app will make a note that the profile was imported.

To connect, simply tap the Connect button. You'll be asked if you trust the OpenVPN application. Choose OK to initiate the connection. Once everything is installed, a simple check confirms everything is working properly.

The site will return the IP address assigned by your internet service provider and as you appear to the rest of the world. That is now how you appear to the world. Occasionally, you may need to revoke a client certificate to prevent further access to the OpenVPN server. This will show some output, ending in error This is normal and the process should have successfully generated the necessary revocation information, which is stored in a file called crl. At the bottom of the file, add the crl-verify option, so that the OpenVPN server checks the certificate revocation list that we've created each time a connection attempt is made:.

The client should now longer be able to successfully connect to the server using the old credential. This process can be used to revoke any certificates that you've previously issued for your server.

You are now securely traversing the internet protecting your identity, location, and traffic from snoopers and censors. To configure more clients, you only need to follow steps 6 , and for each additional device. To revoke access to clients, follow step English Spanish Portuguese Russian.
