LogMeIn Hamachi Getting Started Guide
Learn the basics of working with Hamachi.
What Is Hamachi?
Hamachi is a virtual networking service that can be set up in minutes and enables secure remote access to your business network anywhere there is an Internet connection.
Unlike traditional hardware and software based VPN systems, Hamachi is an on-demand virtual networking service that allows you to focus your time and energy on providing the remote connections your users and systems need, and not the technology or infrastructure you are using to support them.
What are the key features of Hamachi?
Hamachi is our VPN product, and will allow you to setup a Virtual Private Network that will allow you to share data between the computers in your network. Subscription Model:
- Free subscription allows you to have 5 members in a network
- Standard subscription allows you to have 32 members in a network
- Premium subscription or a Central subscription allows you to have 256 members in a network
- Multi-Network subscription allows you to have 256 members in a network and an unlimited number of networks
Features:
- Cloud-based virtual networking: Deliver virtual networking, over the web, without investing in costly hardware or additional IT infrastructure.
- Gateway virtual networking: Provide remote users with secure access to your private network/LAN, including the resources on it, from a centralized Hamachi gateway, without modifying firewalls or network routers.
- Hub-and-spoke virtual networking: Provide remote users with secure access to specific resources on your network, from any location, without modifying firewalls or network routers.
- Mesh networking: Connect all of your network clients to each other. Quickly and easily create a simple, virtual, mesh network that allows remote machines to directly connect to each other, thereby giving users basic network access to all the network resources they need.
- Centralized software deployment: Quickly and easily provision virtual network client software to new computers without having to go on-site. Simply send end-users a link to download and install the client to participate in a specific virtual network.
- Encryption and Security: Hamachi offers secure communications using AES 256-bit encryption, combined with user- and network-level security authentication and locking.
Hamachi Web Management Features

Who Should Use LogMeIn Hamachi?
Here are a few examples of how you can take advantage of Hamachi.
- IT Support: Building a Mobile Office LAN
-
Many mobile workers use their laptops in the office while connected to their company's shared resources (file servers, network printers, mail servers, etc.). 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 Hamachi, mobile workers become members of a Hamachi network wherein all shared resources are also network members. As a result, network configurations can remain unchanged. Hamachi sets up exactly the same networking environment for the mobile user no matter where he is.
Tip: Hub-and-spoke and gateway are the best networking modes for this scenario.
- IT Support: Setting Up Network Access for Home Workers
-
Home workers can be more productive when they have secure access to shared IT resources. Using the Hamachi 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 Hamachi networks for multiple customers. He uses LogMeIn Hamachi to create Hamachi networks, deploy Hamachi clients, and apply default and custom settings for each customer. He can also manage other administrators in his organization, generate client activity reports, and manage network activity.
- Small to Medium Sized Organizations: Virtual LAN
-
Organizations without a physical LAN can use the mesh network type to set up a virtual corporate LAN.
Free versus Paid Subscriptions
Hamachi is free for users if they have no more than five computers per network. The paid version offers fast relays and is subject to an annual subscription fee.
For information about subscription types, see Subscription Types.
LogMeIn Hamachi Security
All LogMeIn Hamachi communications are encrypted and authenticated with industry-standard algorithms and protocols. Nobody will be able to see the data transmitted between two Hamachi peers.
The Hamachi Client
The term Hamachi client refers to both the Hamachi software itself and any computer or smartphone with Hamachi client software installed. With proper permission from network owners, Hamachi clients can become members of any Hamachi network.
The LogMeIn Hamachi client for Windows
The LogMeIn Hamachi client for Mac
A command-line version of LogMeIn Hamachi is also available for Linux and officially supported on the following distributions:
- Ubuntu 16.04 LTS or newer LTS
- CentOS 7.2 or newer
About the Relationship Between the Client and Your Account
The Hamachi client can only be used with a LogMeIn ID, as an attached member of an account.
About the Hamachi Virtual IP Address
Every Hamachi client has one virtual IPv4 (IP) address in the 25.x.x.x range and one IPv6 address. The virtual IP address is globally unique and is used to access the client from any other Hamachi network with at least one common mesh or hub-and-spoke network.
Hamachi Network Types
LogMeIn Hamachi provides three network types for flexibility in meeting diverse use case scenarios. They differ mainly in network topology.
For information about subscription types, see Subscription Types.
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.
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. 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). For example, in a library, the catalog is a hub while workstations accessing the catalog are spokes. Hub-and-spoke is ideal if you want strict control over connections between network members.
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.
About Gateway Networks
Use the gateway network type to provide transparent access to your entire network from a centralized Hamachi 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.
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 Hamachi client and be set up as hubs. This is fine insofar as these shared resources are servers with a Hamachi compatible operating system; however, the gateway network remains the best option since Hamachi currently cannot be installed on network devices such as printers, routers, access points, etc.
Important: Mac hosts cannot act as gateway nodes.
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 as a hub (the gateway), while members act as 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 Hamachi client can be considered members
- Each member (Hamachi client) will see the gateway and the other members of the gateway's LAN
- Hamachi 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 Hamachi network
- The gateway cannot be a workstation that is the member of a domain
- The gateway must not be a DNS and/or DHCP server since the Hamachi network bridge interferes with the DNS and DHCP services.
- Members can join more than one gateway network, but can only be online in one network at a time. Gateway members can also be members of multiple non-gateway networks
Role of the Hamachi Client in a Gateway Network
- Gateway network members and the gateway device itself must be running the Hamachi client
- Network devices that are physically connected to the LAN do not need to run the Hamachi client to be made accessible to gateway network members
Addressing
Gateway networks integrate smoothly into the LAN in terms of addressing. 25.x.x.x addresses are not available for a gateway network. Instead, the local address space is used.
Subscription Types
Free, Standard, and Premium subscriptions are available at the network level. You can have an unlimited number of Free, Standard, and Premium networks in your account, in any combination. Standard and Premium subscriptions are purchased for and applied to individual networks.
Regardless of the type and number of subscriptions you purchase, you can attach a maximum of 256 clients to your account; the number of clients is independent of the number of members per network.
| Subscription type | Valid for this many networks | Members per network |
|---|---|---|
| Free | Unlimited | 5 |
| Standard | 1 (purchased individually, per network) | 32 |
| Premium | 1 (purchased individually, per network) | 256 |
The Multi-Network subscription option is applied across an entire account, allowing you an unlimited number of networks with up to 256 members per network. With Multi-Network you are still subject to the limit of 256 clients per account. The number of clients allowed at the account level is independent of the number of members per network. This means that you can have potentially far more members in your networks than clients attached to your account.
Tip: When attempting to add a new client, you may be informed that you have reached your client limit. If this occurs, you must create "free space" in your account by removing an unused client. Otherwise, the client can only join your network if it is attached to another account and joins your network as a guest.
| Subscription type | Valid for this many networks | Members per network |
|---|---|---|
| Multi-Network | Unlimited | 256 |
Tip: The current and maximum number of network members are displayed on the Hamachi client next to the name of the network. For example, 11/256 means that there are 11 members in a network that can have up to 256 members.
Frequently Asked Questions
- What if I do not want to renew my subscription?
-
Standard, Premium, and Multi-network subscriptions are paid subscriptions that allow you to have more than five members in your network. If your network has more than five members, you should take the following into consideration before you cancel your subscription:
- Your network will not accept any new members.
- Only five members will be active. Other members will be disabled (offline) in your network until you resolve this issue by purchasing a subscription or evicting network members.
- Your network will still be fully functional but only for five randomly selected members.
- You can renew your expired subscription any time.
- What if I never had a paid subscription?
-
For free networks, only five members remain active and you are unable to add new members. For example, a free network that was created with 14 members before introducing Standard, Premium, and Multi-network subscriptions will be functional for five random members and will not accept new members.
Important: If you have more than five members in a network and you choose to have a free subscription, you will not be able to add new members until you remove some of them from the network.

How do I assign an IP Range for Gateway Members?
Gateway members are assigned an IP address by the DHCP server in your gateway's LAN. If no DHCP server is present, the gateway must be configured to behave as a quasi-DHCP server and assign addresses from a defined range.
- Open the UI on the client that is set as the Gateway.
- Right-click the gateway network and select Gateway settings from the menu. The Gateway Settings dialog box is displayed.
- Select the IP Parameters tab.
- Clear the Obtain IP settings automatically box.
- Under Address range, enter the appropriate addresses.
Important: You must complete each field under Address range.
- If you have a DNS server(s) in the network, you may enter their IP addresses or define a DNS suffix.
- Click OK to save your settings.
How to Attach an Unattached Client to an Account
On Windows
An existing Hamachi client running in Client-only mode can be attached to an account at any time.
This procedure must be executed on the client.
- On the Hamachi client under the System menu, select Attach to LogMeIn account.
- Enter the LogMeIn Account ID (email address) of the account to which you want to attach the client.
- Select Attach networks to attach your existing networks to the selected account.
- Click Attach.
Result: Your relationship with the selected account shows as Pending.
What to do next:
The Account Holder or administrator will see the attachment request on the Join Requests page for the specified account. The Account Holder or administrator must approve or deny the request.
Once approved, the client can be managed using the LogMeIn.com website. All networks that were created on the unattached client are also manageable from your account if they are attached to the account.
Tip: Another option is to send an installation link to a user with an unattached client. The user will click the link to reinstall the Hamachi client as an attached member of your account.
Important: You cannot attach a network to a web account that was created on an attached client. You must delete the client from the web account first and then reattach it to add all networks that were created on the client.
On Mac
On a Mac, simply log in to the Hamachi client using the account to which you want to attach the client, as follows:
- On the Hamachi client, click the Power icon.
Result: You are prompted to sign up or log in to continue using Hamachi.
- Click either Log In or Sign Up, as required.
Be sure to use the account to which you want to attach the client.
Result: The Login window is displayed.
- Enter the information requested.
- Select either Login or Create Account, as required.
Result: Your relationship with the selected account shows as Pending.
What to do next:
The Account Holder or administrator will see the attachment request on the Join Requests page for the specified account. The Account Holder or administrator must approve or deny the request.
Once approved, the client can be managed using the LogMeIn.com website. All networks that were created on the unattached client are also manageable from your account if they are attached to the account.
Tip: Another option is to send an installation link to a user with an unattached client. The user will click the link to reinstall the Hamachi client as an attached member of your account.
Important: You cannot attach a network to a web account that was created on an attached client. You must delete the client from the web account first and then reattach it to add all networks that were created on the client.
On Linux
Before you can connect to a network, you must attach the client to your LogMeIn Hamachi account.
- Execute sudo hamachi login to log in.
The login command establishes a link between your computer and the Hamachi server. After your first login, the Hamachi client running on your computer will remember your details and whenever your restart your computer, it will automatically log you in to the Hamachi server.
- Execute sudo hamachi attach [email@example.com] using your LogMeIn ID (email address) to attach the client running on your computer.
Attaching your LogMeIn Hamachi client to an existing LogMeIn Hamachi account is optional and has the following advantages:
- You can manage your networks from the LogMeIn.com website.
- With the attach-net command, you can attach those networks that you have created on your client to a LogMeIn Hamachi account. This way, ownership of those networks will be transferred from the client (that created the networks) to the LogMeIn Hamachi account. This also means that you can manage these networks from the LogMeIn.com website.
What do the Different Color Indicators Mean in LogMeIn Hamachi?
A circle in front of each peer on your Hamachi list is a status indicator.
Note: This functionality is not available on Linux.
The color of this indicator reflects the status of the connection between you and a peer.
| Color | Description |
|---|---|
| grey | The peer is offline. |
| blinking green | The client is trying to establish connection to the peer. |
| solid green | There is a direct link between the client and the peer. |
| blue | There is a relay tunnel between the client and the peer. You may have to set a static TCP or UDP port for Hamachi to use. This is generally necessary when you have a computer behind a router or NAT device and its support of NAT is poor. In this case, you should set up a static port forward on the router/NAT, and then fix a static port in Hamachi. For Port Forwarding, please note that every device is different, and very detailed info per device can be found on www.PortForward.com. If you are setting up port forwarding, it is recommended to set them up for both TCP and UDP protocols, and to keep them the same number.
Note: You do need to enter an IP Address if you have more than one active internet connection. Enter the IP Address of the Local adapter you wish Hamachi to connect through. |
| red | Traffic is blocked between the client and the peer. Right-click on the peer to find out why communication is blocked. |
LogMeIn Hamachi Glossary
Here are a the most commonly used LogMeIn Hamachi terms.
- Gateway network
- Use the gateway network type to provide transparent access to your entire network from a centralized Hamachi 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.
Note: Gateway networks are not supported on Azure.
- Hamachi client
- The term Hamachi client refers to both the Hamachi software itself and any computer or smartphone with Hamachi client software installed. With proper permission from network owners, Hamachi clients can become members of any Hamachi network.
- Hamachi network
- For Hamachi, a network is not a physical network, but rather a group of users who want to use common resources or applications (two or more Hamachi clients interconnected by tunnels make up a Hamachi network). Hamachi 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.
- Mesh network
- In a mesh network, every member is connected to every other member.
- Peer
- A computer that is a member of a computer network.
- Peer Label
- The Peer Label is used to define your online presence to other Hamachi users. This is what other users see as your identification when you are in a Hamachi network.
- Unattached network
- The term Unattached network refers to any Hamachi network that was created on an unattached client. Unattached networks can only be mesh networks and they cannot be managed on the web using the My Networks page or Central.
- VPN
- Virtual Private Network
