FreeVPN
最经D发现，即使拉上电网还是有不听话的天天翻墙出去上网，意识到这是国内技术不过关，于是想起某先人说的一句话：师夷长技以制民，于是花重金从国外买来各种过滤软件加强封锁。就在这种紧要关头，咱们这群坏学生也想起了某先人的一句话：师夷长技以制D，于是从国外网友手中抄录了传说中的5大神器级的免费VPN，本人现内部传阅一下。

Using proxies is highly risky. May be you can use one of these 8 innovative ways to access blocked websites. But then, there is no guarantee that all of them will work. So, what can you do? Use a VPN client.
使用代理有很高的风险，如果你能用8种新方法访问被封锁的网站（上面黄色字体可以链接到那8种方法，类似的，所有黄色字体都是可以链接的）就没有什么问题。如果不能，光靠代理是不能保证每次都能成功。那么，有什么更好的方法？试试VPN客户端吧。
Few days back when I wrote a tutorial on how to access Hulu and Sling outside US, some readers were mentioning how Hulu has blocked Hotspot Shield proxies. But the fact is, HotSpot Shield is just one of the many Free (or cheap) VPN services available on the internet. So, this post is an effort to list out the Top 5 Free VPN Clients currently.
前些天，我写了篇关于在美国以外地区访问Hulu和Sling的教程（英文黄色字体链接），一些网友就提到Hulu最近禁止了通过Hotspot Shield 代理的访问。事实上Hotspot Shield 只是互联网上众多可行的免费（或说是较便宜）的VPN服务。所以这里就列举出了最近的5大免费VPN客户端。
1. AlonWeb – Free VPN client（网站已经被封，要先翻墙才上得去）
（橙色字体下载）
AlonWeb is a free VPN provider. It uses the standard OpenVPN tunneling service by hiding your real IP address enabling you to visit some restricted websites, but injects advertisements to the pages a user browses through their service. The servers are located in the Netherlands and Panama. You have to choose the server on the website. Users are allowed to transfer 1GB of traffic every month. That is enough to browse normal websites, but not for downloading music or movies. With Alonweb you automatically use the OpenDNS-Servers.
AlonWeb 提供免费的VPN服务。他使用 OpenVPN通道服务标准，隐藏你的真实IP地址以允许访问一些受牵制网站，但在使用时会有广告。它的服务器安置在荷兰和巴拿马，你需要选择一个。用户每月只允许使用1GB的流量，这对浏览普通网站是够用的，但对下载音乐和电影是不够用的。在使用AlonWeb时，你将自动使用OpenDNS-Servers（既然是自动就不管是什么东西啦）。
2. PacketiX.NET – Free VPN client（已测可用）
PacketiX.NET is a Japan VPN service. It is actually a premium service, but they have PacketiX.NET online test service as well which is free to use. The service is fast and reliable and it is easy to use as well. Just download the VPN connection manager, install and connect!
