Vita: simple and fast VPN gateway

For example, to install Vita and the Snabb monitoring tool on the local machine:

A Vita network can be as small as two nodes with a single route, and as large as you like. It can be as simple as adding an entry to the IP routing table of your default gateway, to ensure that packets to destinations within your private network are routed over an extra hop: the Vita gateway. To configure a Vita route, you need to specify the address prefix of the destination subnetwork, and the public IP address of the target Vita gateway (in addition to the pre-shared key).
