Networking scheme of Internet café with ADSL

This time, ADSL with its many outstanding skills to get Internet family's widespread favor, the high speed network bandwidth, the security network structure, forever on-line the Super dazzle feeling, plus the Internet does not have to pay the convenience characteristic of the telephone bill, has become the ADSL and its owner's proud capital.

On the internet often see some friends asked about in the ADSL network in the various problems encountered, I feel that everyone is using a more cumbersome method to form their own local area network. I am here with my own ADSL internet cafes experience and talk about my views on this type of networking.

Analysis of common scenarios

At present, Internet cafes and Soho users most of the LAN is the use of a dual network card server sharing ADSL connection method.

　　

The user's ADSL Modem and the server's network card 1 communication, then the server through the network card 2 connected to the hub or switch. This makes it a way for internal users to access the Internet: LAN user → switch → server network card 2→ Server network card 1→ADSL modem→isp (Internet). (Computer science)

But is this networking approach the best way? We all know that there are many proxy server software, Sygate, Wingate and WinRoute. But I found that the problems of the online friends are caused by these software. Here we take sygate as an example, from the version of the software itself, only Syate 4.0 version of the correct support ADSL, so that we used to use the lower version can not continue to use. Sometimes when using the Sygate network, there is a failure that some of the client's Web sites cannot access. If you remove these software problems, the use of dual network card has increased the cost of our network, at the same time, in order to ensure the stability of the network, the general proxy server needs a dedicated computer, which also caused the waste of resources. Moreover, by experience, the general machine in the installation of dual-card after the often some inexplicable problems.
Friends may ask, this networking solution has so many drawbacks, then you have a better way? Friends, don't worry, there is no ink to swim here. Below, I will use all to QL1680 ADSL Modem Network of convenient program to everyone, please see:

Friends have looked at Figure 2, may ask: This networking program can complete the sharing of Internet? Don't worry, let me talk to you slowly.

　　

In this scenario, an internal user accesses the Internet in a different path: The LAN user → switch →adsl modem→isp (Internet). What is the difference compared to the previous scenario? One less server and it's two cards!

The omni-direction QL1680 ADSL Modem has the function of routing, can be used as a router completely, can replace those soft router completely. Because of the routing function in the modem interior, stability is much better, to avoid the soft routing of all kinds of inexplicable maintenance, configuration failures and problems (hear here, friends are not in front of a bright). It is so simple, the whole to QL1680 to switch to any port on a plug, hardware connection all OK. Let QL1680 do all the other things. Configuration is also very simple, as long as we have the PC network card IP set to automatically obtain, Gateway set to ADSL modem IP address, and then start ADSL Modem to dial. So you can surf the Internet. And also save a network card, is very worthy of our pocket is not very rich funds.

See here, you might say, the plan looks good, but what is the actual effect? How many machines can the QL1680 routing function support? Ask a good, QL1680 routing function is how powerful, you have to ask the Omni, I only know their own internet café 50 machines, a 2M ADSL line, fast, user satisfaction much. There is a marked increase in attendance, profits ... Hey. Friends, do not hurry to try?
