Two methods to bypass firewall restrictions

Have you ever encountered this problem? The host of your company or school is equipped with a firewall. Due to the limitations of these firewalls, you cannot view some webpages or access some servers at will, if you return to "yes", congratulations, because I can bypass these firewalls.

Method 1: webpage redirection

Some websites provide webpage redirection functions. The server that provides this function is similar to a proxy. The principle of this method for filtering the firewall is as follows:

Suppose a firewall does not allow users to see the http://www.buxuqu.com site, but can go to a website called http://www.proxy.com, and this website has web page turn function. So that the user can go to the site first, and then enter the http://www.buxuqu.com at the specified location, so that you can access. Because the firewall only blocks requests to the http://www.buxuqu.com, but does not block requests to the http://www.proxy.com ..

The following two websites have the webpage redirection function. You can try it:

Http://www.anonymizer.com/
Http://www.anonymise.com/welcomeJava.html

Method 2: Use software

In this way, a tool software called httport is used: http: // 202.103.134.147/download/swdetail. phtml? Id = 2616. TheProgramIt is mainly to map a port locally to a proxy. Using this function may break through the firewall restrictions. For example, if your computer is blocked by a firewall and only provides an HTTP proxy for you to go out, and you want to use other services such as FTP and POP3, at this point, this software can play a role. However, the software does not support HTTP proxies that require user names and passwords. To use this software, you must have the permission to set proxy in the browser. Since it is easy to use, I will not detail it here. You can try it on your own.

Now, you can freely soar in the infinite network space, and you have successfully bypassed the firewall restrictions!
