Subject to the maximum number of memberships (see below)

Subject to the maximum number of memberships and network capacity (see below).

Both types of client can also use the one-click web-based join option, which allows joining the network by clicking on an HTML link.

Each network can contain up to a specified number of accounts of each type. These limits are the same for all Hamachi networks, regardless of the owner's account type.

In other words, a network can contain 1 owner, up to 16 basic members and up to 256 premium members.

The maximum amount of networks the account can be a member of (including those it owns).

Anyone trying to join the network is required to present a valid network password.

The password must be non-empty and it can be changed by an owner or an administrator.

Anyone is able to join the network just by knowing its name.

The network can be locked to prevent any new members from joining it. This preserves all other access control settings.

All new members will not have full access to the network until manually approved by an owner or an administrator.

An owner or an administrator can evict existing network members. This revokes their membership, but does not prevent them from re-joining the network.

A network can prepare a list of Hamachi clients that cannot join it under any condition.

The ban list is managed by an owner or a network administrator.

An owner of the network can assign one or more network members to be network administrators.

An owner can also control the list of rights assigned to administrators:

• Set network password
• Lock network and modify network access options
• Approve and reject membership requests
• Evict members
• Ban and unban members
• Set welcome and announcement messages (see below)

* Network administrators can only be selected from members having Premium accounts.

An owner or an administrator can set welcome and announcement messages for each network.

A Welcome message is sent to every new member of the network and it is useful for propagating network policies and regulations.

An Announcement message is distributed to every network member and it is good for ... well ... making announcements; e.g. policy changes.

A network can be marked for unencrypted communication, in which case all premium clients in the network will not be encrypting the traffic towards each other.

Premium-to-basic and basic-to-basic traffic will still be encrypted as usual.

This feature is intended for improving the performance of Hamachi network transfers under a load and in situations where even slightest latency is bad.

* Only premium account holders can turn off encryption off in their networks.

Exchanging Instant Messages with online Hamachi peers.

Exchanging Instant Messages with offline Hamachi clients via a server.

* Both clients must be Premium.

Network Messaging, a.k.a. Group Chat, is an option for chatting with all online network members at once in a single chat window.

Basic members are limited to receiving messages only.

Relays are used for connecting Hamachi clients that cannot, for any reason, establish a direct communication channel. Statistically, the chances of requiring a relay when using Hamachi is about 5%.

An option to run the Hamachi client as a system service. This is typically needed when running Hamachi on servers or in setups involving Windows domain authentication.

In the case of a line up at the server, priority login gets the client online faster by processing its requests at a higher priority.

In addition to handling traffic between Hamachi clients, Hamachi can be set up to allow remote access to LAN computers that do not or cannot run the Hamachi client. This is a very powerful feature that essentially allows the tunneling of arbitrary traffic over Hamachi P2P connections.

An option to use Hamachi as a simple web proxy. This way, your Hamachi peers may configure their Web browsers to access the Internet via your computer and therefore protect their Web traffic while it is in transition between you and them.

This feature is typically used for securing Web surfing from untrusted locations including cybercafes, coffee houses, hotels, etc

* Free accounts are limited to proxying to 2.5MB of traffic per Hamachi login. The traffic counter can be reset by re-connecting the proxying Hamachi client to the system.
