4. SocialVPN

SocialVPN (or IP-Over-P2P, as it is also known) is an open-source virtual network that allows end-users to create their own VPNs.

An IPOP virtual network relies on end-to-end tunneling Ethernet or IP via Tincan links. It can also be managed using a control API that allows you to create various VPN overlays.

SocialVPN creates peer-to-peer (P2P), virtual private networks using a social backend such as an XMPP server (JabberNet or Google Chat). This reliable backend can authenticate users securely, keep a list of all parties and establish TLS for X.509 certificate exchanging.

It relies on direct IP connectivity. Multicast support is also provided between two parties, bypassing firewalls, routers, and NATs. It allows IP- and TCP-based applications to communicate seamlessly.

SocialVPN Features:

  • Free and open source
  • IPOP is simple to set up because it works on your existing Internet infrastructure and doesn’t require virtual routers or hardware routers.

  • Remote access to Linux/Windows via RDP or VNC
  • Remote shell access via SSH/SFTP
  • Windows file sharing via SMB/CIFS

5. SoftEther

SoftEther (Software Ethernet VPN Bridge) and VPN Server are compatible with OSX and Solaris as well as Linux and FreeBSD. VPN Bridge is ideal for companies that need to set up site-to-site VPNs. Individual consumers will only require the client and server programs to gain remote access.

SoftEther supports OpenVPN, SSTP, and L2TP protocols. It also features a clone function that allows you to switch between OpenVPN and SoftEther. these are the best OpenVPN alternatives.

SoftEther is able to tunnel through bypass firewalls and NAT firewalls. SoftEther can tunnel over restricted networks that allow only DNS and ICMP packets. Users can use SoftEther’s ‘VPN Over DNS’ or ICMP commands to bypass the firewall.

7. Tcpcrypt

Tcpcrypt protocol can be used as the best open-source VPN alternative because it does not require any configuration changes, nor do you need to make changes to your network or applications.

It is based on the principle of “opportunistic encryption”, which means that the protocol (unencrypted TCP), will remain cleartext and can only be encrypted when another party attempts to communicate with Tcpcrypt.

Tcpcrypt does not get involved in authentication. Instead, it passes a special “session ID” to the application. This ID token can then be used by that application for secure authentication. In other words, certificates, and passwords are also possible to be used as authentication methods.

It is also vital for the client-side, and it also plays an important role in public key connection initiation, reducing DoS attacks and the load on servers.
