The switch is not a computer, but a machine similar to a router. The extranet is a wide area network. If there is only an intranet, you can't browse web pages, It can only do some internal services, such as setting up internal resource sharing, and then clients go to the host to download, but can't download things such as Xunlei, and can't open the website. Therefore, in order to connect users in the intranet to the Internet, the host needs to be able to connect to the Internet...

No matter what broadband you use, as long as you connect to the Internet, you can communicate with the outside world (worldwide), that is, the outside network.
