How about a healthy Internet expert?

I studied 1 1 and Fang Hao. In fact, I got a virtual LAN address after connecting to their platform server. After logging in to the platform, you can use "ipconfig" in the command line tool to check the address change. Similar remote connection software is Kawakes provided by king of fighters Simulator. Some firewalls provide a function called VPN, which enables external users to obtain a virtual intranet IP in order to access the intranet and enjoy it. But I haven't tried ordinary home routers. I tried this function with the company's high-end firewall, and I can connect online. I hope my answer can enlighten you.
