VpnCloud is a high performance peer-to-peer mesh VPN over UDP supporting strong encryption, NAT traversal and a simple configuration. It establishes a fully-meshed self-healing VPN network in a peer-to-peer manner with strong end-to-end encryption based on elliptic curve keys and AES-256. VpnCloud creates a virtual network interface on the host and forwards all received data via UDP to the destination. It can work on TUN devices (IP based) and TAP devices (Ethernet based).
Connecting two nodes can be as easy as:
$> vpncloud --ip 10.0.0.1 --password 'mysecret' -c REMOTE_HOST:PORT
or as a config file:
crypto: password: mysecret ip: 10.0.0.1 peers: - REMOTE_HOST:PORT
