/* * anytun * * The secure anycast tunneling protocol (satp) defines a protocol used * for communication between any combination of unicast and anycast * tunnel endpoints. It has less protocol overhead than IPSec in Tunnel * mode and allows tunneling of every ETHER TYPE protocol (e.g. * ethernet, ip, arp ...). satp directly includes cryptography and * message authentication based on the methodes used by SRTP. It is * intended to deliver a generic, scaleable and secure solution for * tunneling and relaying of packets of any protocol. * * * Copyright (C) 2007 anytun.org * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License version 2 * as published by the Free Software Foundation. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
