Using Real-Time ADSL modem for shared network connection (1)

With the rapid development of Internet technology, the wave of informatization is approaching. With the rapid development of communication technology, Internet users and business volume are growing at an extraordinary speed, and people have higher and higher requirements on network bandwidth and quality.
As a mature broadband access technology, ADSL, with the advantages of fast transmission speed, simple installation and use, saving investment, "surfing the Internet" and "talking", and high-speed network interconnection and sharing, more and more users are accepting the advantages.

When talking about Internet sharing, we can use the ADSL Modem with the routing function, and use the NAT Function of Internet sharing provided by Windows to easily achieve multi-user access. NAT refers to Network Address Translation (NAT), which is also called an Internet route connection. It is an IETF standard that allows an organization to appear on the Internet as an Address. NAT converts the addresses of each LAN node into one IP address. It can also be applied to the firewall technology to hide individual IP addresses from external discovery, so that the outside world cannot directly access internal network devices. At the same time, it also helps the network go beyond the address restrictions, reasonably arrange the use of public and private IP addresses in the network. NAT-based efficiency, security, and ease of use have become the best choice for ADSL Internet sharing.

To enable more users to experience the charm of fast Internet access through multiple ADSL hosts and the new experience brought about by broadband access technology, we will introduce adsl modem4.x using the bandwidth modem at 2516PPPoE) related NAT network sharing settings. As we all know, the HTTP port number is 80. Assume that the IP address of the NIC of the computer that provides WEB Services is 192.168.10.5. The steps for configuring NAT are as follows:

1. Open IE and enter 192.168.10.1 in the address bar. The following page is displayed:

Click OK to go to the modem web configuration page: 2. Click Services. The following page is displayed: 3. Drop down the small arrow on the Right of NAT Options and select the second option NAT Rule Entry. The following interface is displayed:
