Tunnel Setup Protocol

FREENET6's TSP is a new model based on a client/server approach, a protocol is used to request a single IPv6 address to a full IPv6 prefix from a client to a tunnel server. We can use Freenet6 as an anonymous user or as an authenticated user:

• Anonymous user of Freenet6 will not have a static IPv6 assigned to them, the address will change when we run again the TSP client and Freenet6 provides one single IPv6 address to a client without authentication. If the IPv4 address changes then the IPv6 assigned will change also. Anonymous tunnels will expire 5 days after the last TSP client connection.
• If we are authenticated users Freenet6 provides one single address and a /48 IPv6 prefix to a client after a successful authentication to the server. If we have a dynamic IPv4 address, we will be able to update our tunnel each time our IPv4 changes by running the TSP client and preserving the IPv6 address. Authenticated tunnels will expire 3 months after the last TSP client connection.
