L2TP (Ubuntu) server setup for iOS clients
I suppose my kernel maybe does not support NAT-T. It's included by default in Ubuntu Sorry, your blog cannot share posts by email. I cannot seem to get this working. In this step we create an additional secret key that is shared with both the server and the clients. By default, OpenVPN runs as the root user and thus has full root access to the system.

How To Setup IKEV2 Strongswan VPN Server on Ubuntu For iOS / iPhone

The name of your duplicated client. Instead, you should duplicate client. Once named, we then must open DigitalOcean. The first area of attention will be for the IP address of your Droplet. Next, find the area shown below and uncomment user nobody and group nogroup , just like we did in server. This doesn't apply to Windows so you can skip it. 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.

To merge the individual files into the one unified profile, the contents of the ca. The XML at the end of the file should take this form:. Save the changes and exit. We now have a unified OpenVPN client profile to configure our client1. 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. In our example, since the file was named DigitalOcean. Choose the appropriate installer version for your version of Windows. 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 it 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 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 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 the the VPN can be connected and disconnected as needed; it does not actually make the VPN connection. This opens the context menu. Select DigitalOcean at the top of the menu that's our DigitalOcean. 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 DigitalOcean. 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 DigitalOcean connection. To transfer your iOS client profile 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.

You are now securely traversing the internet protecting your identity, location, and traffic from snoopers and censors. We hope you find this tutorial helpful. In addition to guides like this one, we provide simple cloud infrastructure for developers. Not using Ubuntu Choose a different version: 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?

Prerequisites The only prerequisite is having a Ubuntu After completion of this tutorial, It would be a good idea to create a standard user account with sudo privileges for performing general maintenance on your server. This can be done with one command: You will see a section looking like this: Generate your own with: It should look like this when done: The last area to change in server.

You can uncomment this out on non-Windows systems. Now save your changes and exit Vim. Packet Forwarding This is a sysctl setting which tells the server's kernel to forward traffic from client devices out to the Internet. Enable packet forwarding during runtime by entering this command: 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. First set ufw to allow SSH. Custom rules should be added to one of these chains: Enter into the command prompt: Command may disrupt existing ssh connections.

Proceed with operation y n? The result will be this output: Firewall is active and enabled on system startup To check ufw's primary firewall rules: First copy over the Easy-RSA generation scripts. However, this time there are two additional prompts: Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []: An optional company name []: Two additional queries at the end require a positive y response: At this point, the OpenVPN server is ready to go.

Start it and check the status. VPN 'server' is running Congratulations! No such file or directory That error indicates server. Key and Certificate Building It's ideal for each client connecting to the VPN to have its own unique certificate and key.

As before, these two confirmations at the end of the build process require a y response: In this example, our client1 device requires its certificate and key, located on the server in: You can have multiple remote entries to load balance between the servers. Fortunately, I have a router that will pass protocol 50 Dlink Dir -- I think many cheapo routers will not do this.

Experiment to find what works for you. I took them all out. The authentication stuff all seems to be working. Ipsec connects fine and the VPN appears to establish normally on the iPhone. If I open Safari, I cannot get to any external sites. Actually, I can browse to local sites within my LAN. I am also not certain I have nat traversal working. I think nat traversal should be working with the kernel I am running Linux clark 2.

Ok, there's a lot of information. Any suggestions would be greatly appreciated. Last edited by Apollo77; at Ok, well, maybe this will help someone. I found the problem while reading this: This is that file now: Apparently, the 2nd reverse line is also required because chap authentication needs to work in both directions.

Actually, I thought my configuration was refusing chap, so I remain confused about that. Oh well, it works. Other things I did that are probably necessary: This should fix that.

The VPN connection establishes in just a few seconds. The connection occasionally drops, but in general it is quite reliable. If you can get this working, you will be pleased. I wish this were easier to setup. I want to do the same thing from Android. Does it work with Dynamic DNS addresses? The iphone is on a dynamic IP address when connected over 3G. If your VPN server is on a dynamic address, that adds a complication you will need to work out.

There are services like DynDNS that can help with that One thing I have noticed is that my particular VPN setup seems to work only for the iphone. I have tried to set up a VPN from my laptop running windoze and I cannot connect. Maybe I could get it working for both, but it's not worth the effort from my laptop -- I just funnel traffic I want encrypted through an SSH tunnel instead I'd be interested to know if anyone else gets this working on the iphone.

Last edited by bleargh; at I run Tomato also. I could be wrong, but I don't think the "protocol 50" thing mentioned in one of my earlier posts is necessary. I suppose if the IP address changed during a connection then you would get dropped, but that would be a rare event. Local web sites ie.

Regular web browsing is actually a bit slower when connected to the VPN because my upload speed at home becomes the download speed on the iphone. In downtown Toronto where I work this makes little difference because of existing network congestion -- I rarely see kbps download on 3G downtown connected to the VPN or not.
