After that, you can find the VPN you just set in the network connection area in the upper-right corner of the network, and click it to access the Internet through the VPN.

That bras is used by the South China University Intranet to the Internet. Other schools may have their own methods. In fact, the most important thing is that the network manager cannot use the VPN without the PPTP protocol. Therefore, the key is to install PPTP. It can be used directly after version 10.04. It's no longer so troublesome, bless
