Use a proxy in Firefox to access the Internet for free without logging on to the client.

Education Network uses IPv6 proxy for free Internet access (the premise is that you are in a place where you can use education network, such as in school)

1. First, check whether your computer's IPv6 environment is installed. win7/Vista users have IPv6, while XP users need to install it manually. Press win + R and Enter cmd and press enter to bring up the command line window, enter an IPv6 space, install, and press enter, over.

2. Open the Firefox browser, select "options" in the tool, select "advanced", select "connection" in "network", and open "Settings ". In "connection settings", select manually set proxy.

The settings are as follows:

The HTTP Proxy item can also be used:

Edu6.zzzcn.info port 2012;

Edu.zzzcn.info port 2012;(These two are my most common ones .)

Bv66.zzzcn.info port 2012;(The above three are actually three servers planned for the VPN, and one is down and the other is changed. You can also create three configuration files for manual switching .)

3. You don't have to log on to the client. You can try it on many websites.
