The communist Chinese government has been filtering much of what the Chinese people are able to access on the
Internet. Therefore, proxy servers have been very helpful for the Chinese to get around these government filters. One of the best proxy servers originally setup to circumvent the government filters is UltraSurf. It is a stand-alone program that reconfigures and redirects the Microsoft Internet Explorer’s proxy settings. UltraSurf servers also employ a range of IP addresses which makes it harder to block. I have provided a free proxy server list of some of the top proxies at the end of this article.
Proxy servers have been around a long time. Microsoft developed a proxy server program to help speed up computer Internet access by caching common searches, which frees up valuable bandwidth by redirecting searches to the cache. Proxy servers also allow filtering of IP addresses and content. Individual IP addresses can be blocked along with words, phrases, or domain names.
Tunneling is a term used with proxy servers because proxies can easily penetrate network firewalls and filters by rerouting searches and traffic through the proxy servers. Proxies act as a go between for all traffic that would otherwise be blocked by filters by capturing the traffic and rerouting. This technique allows you to tunnel or pass right through a filter. Filters block IP addresses so the proxy by using a different IP address can reroute the traffic through an unblocked IP address. Network administrators need to be aware of the most commonly used proxies and block the ranges of IP addresses most used by the proxies.
WARNING!!! The dangers in using free proxies are that many hackers setup free proxies to steal credit cards and other personal information. When connecting to a proxy all your data moves through their server so they are able to capture and monitor all data and content.
WARNING!!! Again use caution when using a proxy and remember all data and content can be easily captured and monitored. So never make purchases or use credit cards, or connect to email or other accounts using ids and passwords, because your accounts and credit cards can be easily compromised.
The number one proxy on the free proxy server list is UltraSurf. They have high performing servers and high bandwidth connections to the Internet. Number two would be freeproxyserver.net, three is hidemyass.com, and four is turbohide.com.
Important Note: Remember use proxies at your own risk and/or peril.
