It can be used to build high scalable and redundant tunnel services. It supports both UDP and TCP connections. Additionally to the possibility of establashing an unicast TCP connection over an anycast address as suggested in rfc1546, it supports real anycast TCP connections with state syncronisation and heuristic state forecast. It also has a relay mode, that makes 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</t> <t><xref target="RFC3068">RFC3068</xref> DTD.</t> - <section> <section title="Operation modes"> <section title="Tunnel modes"> @@ -63,7 +62,12 @@ <section title="unicast tcp with anycast initialisation"> </section> <section title="full anycast tcp"> + <section title="keep alive message request"> + <t>Most NAT routers need a tcp connection to transmit some packets once in while to stay open.
