[. . . ] But if a user moves away from the local network, he will no longer be able to access these resources. Software that is configured to work inside the office becomes useless outside the office. Using Hamachi², mobile workers become members of a Hamachi² network wherein all shared resources are also network members. Hamachi² sets up exactly the same networking environment for the mobile user no matter where he is. [. . . ] Any LogMeIn account holder can manage attached clients on the web using the My Networks page, while LogMeIn Central subscribers can use LogMeIn Central. 4 LogMeIn Hamachi² ­ Getting Started About the Hamachi Virtual IP Address Every Hamachi² client has one virtual IP address in the 5. x. x. x range. The virtual IP address is globally unique and is used to access the client from any other Hamachi² network with at least one common mesh or hub-and-spoke network. The virtual IP address does not conflict with any other IP ranges and therefore has no impact on standard network communications.

Hamachi² clients can be members of any network; however, there is a limit of 16 members per network for a non-commercial license, or 256 per network owned by a commercial license holder or LogMeIn Central subscriber. About Mesh Networks In a mesh network, every member is connected to every other member. Organizations without a physical LAN can use the mesh network type to set up a virtual corporate LAN. Mesh is also the typical choice for gamers, because network games constantly have to broadcast their current status to all other participants in the game. Figure 2: Mesh network Note: Mesh is the only network type that can be created directly from the Hamachi client interface. About Hub-and-Spoke Networks In a hub-and-spoke network, one or more computers act as hubs, while other clients connect as spokes. Hub-and-spoke is typically used when a workstation (spoke) needs to connect only to servers (hubs). Hub-and-spoke is ideal if you want strict control over connections between network members. Figure 3: Hub-and-spoke network Important: If you set every member of a hub-and-spoke network to be a hub, you essentially turn the network into a mesh network. Similarly, if you set only spokes, your members will be unable to make a connection. 6 LogMeIn Hamachi² ­ Getting Started About Gateway Networks Use the gateway network type to provide transparent access to your entire network from a centralized Hamachi² gateway. Members of a gateway network, such as mobile workers, will see one computer acting as a gateway towards an entire LAN, thus making all network resources accessible. Figure 4: Gateway network Tip: Theoretically, a hub-and-spoke network would also be a good choice for enabling mobile LAN access; however, all shared resources would also need to be running the Hamachi² client and be set up as hubs. This is fine insofar as these shared resources are servers with a Hamachi² compatible operating system; however, the gateway network remains the best option since Hamachi² currently cannot be installed on network devices such as printers, routers, access points, etc. Characteristics The gateway network type is a hybrid of the meshed and hub-and-spoke network types: · As in a hub-and-spoke network, one computer acts like a hub (the gateway), while members act like spokes · There can only be one gateway, which is typically a permanently online server connected to the LAN · The number of members is virtually unlimited since even network devices that are not running the Hamachi² client can be considered members · Each member (Hamachi² client) will see the gateway and the other members of the gateway's LAN · Hamachi² clients will not see each other in a gateway network Restrictions For technical and security reasons there are strict rules for both the gateway and members: · The gateway cannot be a member of any other network · Members can join more than one gateway network, but can only be online in one network at a time · The gateway cannot be a workstation that is the member of a domain Role of the Hamachi² Client in a Gateway Network · Gateway network members and the gateway device itself must be running the Hamachi² client · Network devices that are physically connected to the LAN do not need to run the Hamachi² client to be made accessible to gateway network members Addressing Gateway networks integrate smoothly into the LAN in terms of addressing. Instead, the local address space is used.

The commercial version offers fast relays, allows up to 256 computers per network, and is subject to an annual subscription fee. 8 LogMeIn Hamachi² ­ Getting Started LogMeIn Hamachi² Security All LogMeIn Hamachi² communications are encrypted and authenticated with industry-standard algorithms and protocols. Nobody will be able to see the data transmitted between two Hamachi² peers. For detailed information, see the LogMeIn Hamachi² Security Whitepaper. LogMeIn Hamachi² and Firewalls If running a firewall application, you may need to ensure that Hamachi² is able to access the Internet. Please refer to the LogMeIn Hamachi² Knowledge Base for up-to-date information for working with various popular security suites.

[. . . ] With proper permission from network owners, Hamachi² clients can become members of any Hamachi² network. Hamachi² network For Hamachi², a network is not a physical network, but rather a group of users who want to use common resources or applications (two or more Hamachi² clients interconnected by tunnels make up a Hamachi² network). Hamachi² offers three network types: meshed, hub-and-spoke, and gateway. Hub-and-spoke network In a hub-and-spoke network, one or more computers act as hubs, while other clients connect as spokes. Spokes connect to hubs, but never to each other. LogMeIn Central LogMeIn Central is LogMeIn's Essential Remote Services solution for IT professionals and small and medium businesses. Certain premium Hamachi² features are only available to LogMeIn Central subscribers.
