1. Know the IP or domain name of the extranet of the Internet bar.

2. Map the two ports of the hosts 5800 and 900 to the remote ports of the route, or configure the DMZ host on the router.

Using a client to connect to a remote host uses port 5800, and using a browser to connect to the host uses port 5900.
