minivtun

A fast secure and reliable VPN service in non-standard protocol for rapidly deploying VPN servers/clients or getting through firewalls

Key features

• Fast: direct UDP-encapsulated without complex authentication handshakes.
• Secure: both header and tunnel data are encrypted, which is nearly impossible to be tracked by protocol characteristics and blocked, unless all UDP ports are blocked by your firewall; spoofed packets from unauthorized peer are dropped immediately.
• Reliable: communication recovers immediately from next received packet from client after the previous session was dead, which makes the connection extremely reliable.
• Rapid to deploy: a standalone program to run; all configuration are specified in command line with very few options.

Examples

Server: Run a VPN server on port 1414, with local virtual address 10.7.0.1, client address space 10.7.0.0/24, encryption password 'Hello':

/usr/sbin/minivtun -l 0.0.0.0:1414 -a 10.7.0.1/24 -e Hello -d

Client: Connect VPN to the above server (assuming address vpn.abc.com), with local virtual address 10.7.0.33:

/usr/sbin/minivtun -r vpn.abc.com:1414 -a 10.7.0.33/24 -e Hello -d

Multiple clients on different devices can be connected to the same server:

/usr/sbin/minivtun -r vpn.abc.com:1414 -a 10.7.0.34/24 -e Hello -d
/usr/sbin/minivtun -r vpn.abc.com:1414 -a 10.7.0.35/24 -e Hello -d
/usr/sbin/minivtun -r vpn.abc.com:1414 -a 10.7.0.36/24 -e Hello -d
...
