General anytun Internet-Draft Anycast tunneling / relaying The anycast tunneling (anytun) protocol defines a protocol used for communication between unicast clients and anycast servers. It can be used for tunneling information between 2 clients or in relay mode to transmit data form the client over the servers to a third party not using the protocol and vice versa.

anytun defines a Host Anycast Service rfc1546. It can be used to build high scalable and redundant tunnel services. It also supports an IPv4 relay mode, make it possible, that only one of the connection endpoints has to use the anytun protocol. This can be used to make connections through Firewalls or behind a NAT Router RFC3068 DTD. ...

In tunneling mode the payload of the anytun packet is transmitted from one unicast host to the anycast server. This server makes a routing descision based on the underlying protocol and transmits a new anytun package to one or more clients depending on the routing descition.

In relay mode a client using the anytun protocol builds a connection
