The virtual private network daemon vpnd is a daemon which connects two networks on network level either via TCP/IP or a (virtual) leased line attached to a serial interface. All data transfered between the two networks are encrypted using the unpatented free Blowfish encryption algorithm.
vpnd is not intended as a replacement of existing secured communications software like ssh or tunneling facilities of the operating system. It is, however, intended as a means of securing transparent network interconnection across potentially insecure channels.
