User manual LOGMEIN HAMACHI 2 GETTING STARTED

[. . . ] Using the Hamachi² client, home workers gain a secure tunnel directly into their company's network. They can work from home and still access the resources they need. Tip: Hub-and-spoke and gateway are the best networking modes for this scenario. Outsourced IT: Managing Multiple Networks A service provider with a number of administrators on his team wants to set up and maintain multiple Hamachi² networks for multiple customers. [. . . ] Spokes connect to hubs, but never to each other. 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. 5. x. x. x addresses are not available for a gateway network. 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. Copyright © 2003-2010 LogMeIn, Inc. 9 Installing LogMeIn Hamachi² System Requirements Hamachi² client · Operating System: Windows XP, Windows 2000, Windows 2003, Windows Vista, Windows 2008, Windows 7 · Internet connection · There are no special hardware requirements How to Install the Client to a Local Computer Follow this procedure to download and install the Hamachi² client to a local computer. The client will be attached to your LogMeIn account. Important: You must be logged in to the LogMeIn account to which you want to attach the new Hamachi² client. On the LogMeIn web site, switch to Network mode and click Add Client. The recipient must click on the installation link to actually install the client on the chosen computer. Once installation is complete, the client can be used to create and connect to Hamachi² networks. How to Install the Client in Client-Only mode Follow this procedure to download and install the Hamachi² client without associating it with a LogMeIn account. Important: Do not log in to your LogMeIn account. [. . . ] When prompted to attach the client to your LogMeIn Account, be sure to select Attach networks and click Attach. You will now be able to manage your Hamachi² clients and networks on the web. 12 LogMeIn Hamachi² ­ Getting Started LogMeIn Hamachi² Glossary Attached client The term Attached client refers to any Hamachi² client that has been added to a LogMeIn account. Any LogMeIn account holder can manage attached clients on the web using the My Networks page, while LogMeIn Central subscribers can use LogMeIn Central. Gateway network 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. Hamachi² client The term Hamachi² client refers to both the Hamachi² software itself and any computer with Hamachi² client software installed. 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).
