Hamachi 2.1.0.215

LogMeIn Hamachi 是一套VPN的連線軟體，但不同於一般的VPN，就算電腦位於防火牆後方，只要安裝它，也能提供VPN的功能。 透過它，像是遠端的搖控軟體或是存取資料，都可無視防火牆的Policy，而進行作業，因此我們可以利用這套軟體，建立一個屬於自己的虛擬區域網路。

• 採用Web介面，可遠端佈署和簡單管理。
• 可透過中央派送、安裝和設定。
• 提供Gateway virtual networking、Hub-and-spoke及Mesh networking三種網路模式。
• 提供AES 256-bit網路加密。
• 可用中央控管網路上的存取控制，控制項目包括密碼管理、網路認證等。

# Fixes
* Multicast DNS
- In some cases, LogMeIn Hamachi stopped unexpectedly when multicast DNS (mDNS) packets were transferred. This issue affected Windows, Mac, and Linux clients.
* VPN Alias
- In some cases, peer-to-peer (P2P) connection was lost when you assigned an IPv4 address to the peers of your network. As of this release, P2P connection is reliable when using VPN alias. This fix affects Windows, Mac, and Linux clients.
* Kernel extension (kext) issue
- In some cases, a Hamachi client update did not refresh the necessary kernel extension. As a result, the Hamachi virtual network adapter did not work properly.
* Update notification
- In some rare cases, a message about not having new client updates was incorrectly displayed twice. This issue only occurred when you checked for client updates manually and then automatic updates were run that did not retrieve new client updates either. In this case, a message was displayed both after manual and after automatic checks were run.
