g其WAN侧的全局IP 118.18.81.33。但真正的电子邮件服务器位于LAN侧，网关是电子邮件服务的端口转发器。NAT环回允许您从内部NAT本地网络访问WAN全局IP地址。当您在网络中运行服务器时，它非常有用。例如，若您在LAN端设置了邮件服务器，当启用NAT环回功能时，您的本地设备可以通过网关的全局IP地址访问该邮件服务器。无论是在LAN端还是在WAN端访问电子邮件服务器，都不需要更改邮件服务器的IP地址。虚拟计算机“虚拟计算机”允许您将LAN主机分配给全局IP地址，以便它们对外界可见。尽管如此，它们作为Intranet中的客户端主机也受到网关防火墙的保护。例如，如果您在LAN端设置了本地IP地址为10.0.75.102、全局IP地址为118.18.82.44的FTP文件服务器，则远程用户可以访问隐藏在NAT网关后面的文件服务器。这是因为网关负责对IP地址的所有访问lobal IP 118.18.81.33 from its WAN side. But the real E-mail server is located at LAN side and the gateway is the port forwarder for E-mail service. NAT Loopback allows you to access the WAN global IP address from your inside NAT local network. It is useful when you run a server inside your network. For example, if you set a mail server at LAN side, your local devices can access this mail server through gateway’s global IP address when enable NAT loopback feature. On either side are you in accessing the email server, at the LAN side or at the WAN side, you don’t need to change the IP address of the mail server. Virtual Computer "Virtual Computer" allows you to assign LAN hosts to global IP addresses, so that they can be visible to outside world. While so, they are also protected by the gateway firewall as being client hosts in the Intranet. For example, if you set a FTP file server at LAN side with local IP address 10.0.75.102 and global IP address 118.18.82.44, a remote user can access the file server while it is hidden behind the NAT gateway. That is because the gateway takes care of all accessing to the IP address, including SMTP service port 25 and POP3 service port 110. So, the remote user can access the E-mail server with the gateway’s
