8 Free Open Source VPN
👨💻
A Virtual Private Network (VPN) is a private data network that uses the public communications infrastructure (Internet), and maintains privacy through the use of tunneling protocol and security measures. The idea of a VPN is to give a company or person the same capabilities at a much lower cost by using shared public infrastructure rather than private infrastructure. In our case, we use a VPN to connect you to our servers in Europe and Asia.
😭 😍 😂 Top 10 Free VPN with UK US Server [ Best Speed ]
- Protect your computer from attacks and intrusions on the Internet.
- Prevents from unauthorized access to your computers from the Internet.
- Filter network spam by our servers’ firewall system.
- Anonymize, secure all your internet traffic and replace your IP address.
- Works with VOIP, web browsing, email, p2p, ftp, instant messaging, streaming, gaming, etc.
If a free VPN isn’t your cup of tea or you find it unreliable, try this paid VPN. Based on my own experience, VyprVPN is really reliable and good. They are from Germany and have their own unique “Chameleon” technology which sets them apart from other VPNs that use the same open source technology.
- NordVPN | Comes with P2P servers, 100% no log. Pay 1 year and get 2 years free! 70% off!
- VyprVPN | Unique Chameleon VPN Technology Beats VPN Ban
Together with the VPN service, they create a connection called a VPN. This is a secure connection that encrypts all your information and no one else can read it, so wherever you are your privacy is always preserved! The best part is that there is no software to install because most VPN works on all platforms including Windows, Mac, Linux, IPhone, etc using the VPN software that is built into your operating system. Without further ado, here are 9 open source VPNs that can be used with a VPN gateway.
Libreswan is a free application of the most widely supported and standardized VPN software based on Internet Key Exchange (“IKE”) (“IPsec”). These standards are produced and maintained by the Internet Engineering Task Force (“IETF”). Libreswan does some additional hardening of the IKEv1 protocol that has not been implemented in other applications. This is not a vulnerability and CVE-2016-5361 has been incorrectly released.
OpenConnect is an SSL VPN client initially built to support Cisco’s AnyConnect SSL VPN. It has since moved to support Juniper SSL VPN which is now known as Pulse Connect Secure. OpenConnect is released under the GNU Lesser General Public License, version 2.1. Like vpnc, OpenConnect is not officially supported or associated with Cisco Systems, Juniper Networks, or Pulse Secure in any way. It just happens to handle their equipment. Development of OpenConnect began after the Cisco client experience under Linux found that it had several shortcomings:
- Not being able to use SSL certificates from a TPM or PKCS#11 smart card, or even use a passphrase.
- No support for Linux systems other than i386.
- Lack of integration with NetworkManager on Linux desktop.
- Lack of proper encapsulation (RPM/DEB) for Linux distributions.
- The “daemon” use of libraries with dlopen(), even using only development symlinks like libz.so – making it difficult to detect what dependencies the appropriate packages would have expressed
- Tempfile sprints allow non-privileged users to trick it into overwriting random files, as root.
- Unable to run as a non-privileged user, which may reduce the severity of the above error.
- Not being able to audit the source code for more “Security 101” errors.
Naturally, OpenConnect addresses all of the above issues and more.
- Connection through HTTP proxy, including libproxy support for automatic proxy configuration.
- Connect via SOCKS5 proxy.
- Automatic detection of IPv4 and IPv6 addresses and paths.
- HTTP Forms Authentication.
- Authentication using SSL certificates – from a local file, trusted platform module, and PKCS#11 smart cards.
- Authentication with SecurID tokens (when generated with libstoken)
- Authentication using OATH TOTP or HOTP tokens.
- Authentication with Yubikey OATH tokens (when generated with libpcsclite)
- UserGroup support to choose between multiple configurations on a single VPN server.
- Data transfer via TCP (HTTPS) or UDP (DTLS or ESP).
- Keepalive and Dead Peer Detection on both HTTPS and DTLS.
- Automatic update of VPN server list / configuration.
- Roaming support, allowing reconnection when changing the local IP address.
- Run without root.
↓ 03 – OpenSwan | linux
Openswan is an IPsec app for Linux. Supports most extensions (RFC + IETF drafts) related to IPsec, including IKEv2, X.509, NAT Traversal digital certificates, and many others. Openswan has been the de-facto virtual private network software for the Linux community since 2005. If you’re running Fedora, Red Hat, Ubuntu, Debian (Wheezy), Gentoo, or many others, it’s already included in your distribution! Just start using it right away.

↓ 04 – OpenVPN | Windows | Mac | Android | iOS
OpenVPN is a full-featured open source SSL VPN solution that accommodates a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-grade remote access solutions with load balancing, failover, and fine controls granular access. Starting with the basic premise that complexity is the enemy of security, OpenVPN offers a cost-effective and lightweight alternative to other well-targeted VPN technologies for SMB and enterprise markets. With OpenVPN, you can:
- Tunnel any IP subnet or virtual Ethernet switch over a single UDP or TCP port,
- Configure a scalable, load-balanced VPN server farm with one or more devices that can handle thousands of dynamic connections from incoming VPN clients,
- Use all the encryption, authentication, and authorization features of the OpenSSL library to protect your network traffic as it traverses the Internet,
- Use any cipher, key size, or HMAC digest (for datagram integrity check) that the OpenSSL library supports,
- Choose from traditional hard key-based encryption or certificate-based public key encryption,
- Use pre-shared static keys or TLS-based dynamic key exchange,
- Using real-time adaptive link compression and traffic shaping to manage link bandwidth usage,
- tunnel networks whose public endpoints are dynamic such as DHCP or demand clients,
- tunnel networking through connection-oriented state-of-the-art firewalls without the need to use explicit firewall rules,
- Tunneling networks via NAT.
- Create secure Ethernet bridges with virtual clickers, and
- Control OpenVPN with a graphical user interface on Windows or macOS.
↓ 05 – SocialVPN | Windows | CentOS | Ubuntu | OpenWRT directives
SocialVPN is an open source IPOP-based virtual network that connects your computers privately with your friends’ computers. It automatically maps online social networking relationships with Jingle and XMPP to create user-defined peer-to-peer VPNs – no hassle, support for unmodified TCP/IP applications.
In SocialVPN, each user controls who the VPN connects to. To expand into large online social networks, SocialVPN uses a unique method of dynamic IPv4 address assignment/translation that avoids conflict with local networks and devices outside the user’s social network. These are some of the ways you can use SocialVPN:
- Sharing private data – SocialVPN allows you to create all-inclusive VPNs that connect you with your friends. You can use these links to share data privately with your friends, using existing applications to transfer and share files.
- Mobile Cloud Computing – SocialVPN runs on Android devices and allows users to create VPNs that connect mobile devices as well as desktops, laptops, and servers. It provides a basis for research and development in “social area networks” for data sharing and computational decoding.
- Decentralized OSNs – SocialVPN creates a communications overlay that can be used as a basis for designing decentralized OSNs.
