**VpnCloud** is a simple VPN over UDP. It 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). Tunneling traffic
between two nodes can be as easy as:
```
vpncloud -c REMOTE_HOST:PORT --ifup 'ifconfig $IFNAME 10.0.0.1/24 mtu 1400 up'
```
More details can be found in [the manpage](vpncloud.md).

All connected VpnCloud nodes will form a peer-to-peer network and cross-connect
automatically until the network is fully connected. The nodes will periodically
exchange information with the other nodes to signal that they are still active
