Additionally 1.0 series of client software are capable of relaying traffic through vendor-maintained 'relay servers'. This process does not work on certain combinations of NAT devices, requiring the user to explicitly set up a port forward. Detailed information on how it works has not been made public. When establishing tunnels between the peers, Hamachi uses a server-assisted NAT traversal technique, similar to UDP hole punching. When a member of a network goes online or offline, the server instructs other network peers to either establish or tear down tunnels to the former. The synchronization step brings a client's view of its private networks in sync with other members of these networks. The discovery is used to determine the topology of the client's Internet connection, specifically to detect the presence of NAT and firewall devices on its route to the Internet. The login step authenticates the client to the server and vice versa. When the connection is established, the client goes through a login sequence, followed by the discovery process and state synchronization. The Windows version also recognizes and tunnels IPX traffic.Įach client establishes and maintains a control connection to the server cluster.

Hamachi currently handles tunneling of IP traffic including broadcasts and multicast. Outbound traffic sent by the operating system to this interface is delivered to the client software, which encrypts and authenticates it and then sends it to the destination VPN peer over a specially initiated UDP connection. Client software adds a virtual network interface to a computer, and it is used for intercepting outbound as well as injecting inbound VPN traffic. Hamachi is a proprietary centrally-managed VPN system, consisting of the server cluster managed by the vendor of the system and the client software, which is installed on end-user computers.
