During this time, ADSL gets a wide range of personal skills, high-speed network bandwidth, safe network architecture, always online, more popular, and add online without having to pay the phone. ADSL and its owners proud capital. I often saw some friends asked about the problems encountered in the ADSL network, I feel that everyone is using a troublesome way to form their own local area network. Here I talked about some views on this networking method with their own ADSL Internet cafes experience and everyone. Analysis of Common Schemes At present, most of Internet cafes and SOHO users use the local area network to share ADSL connections through a dual-NIC server (shown in Figure 1):
figure 1
The user's ADSL MODEM and server network card 1 communication, then, the server is connected to the HUB or switch via the NIC 2. In this way, it constitutes an internal user access to the Internet: LAN User → Switch → Server NIC 2 → Server NIC 1 → ADSL MODEM → ISP (Internet). But this networking method is not the best way? Everyone knows that the agent server software has a variety of, Sygate, Wingate, and WinRoute. But I found that problems in the online friends are taken out by these software. Here we use Sygate as an example, from the software itself, only Syate 4.0 or higher version can support ADSL correctly, so that the low version of us cannot continue to use. Sometimes when using the Sygate network, there is a fault where the client cannot access. If you remove these software issues, use dual network cards to add our networking cost; in order to ensure the stability of the network, the general proxy server requires a special computer, which also causes the waste of resources. Moreover, with experience, the general machine often has some inexplicable problems after installing the Double NIC. My choice of friends may ask, this kind of network plan has so many shortcomings, then have you have a better way? Don't worry about it, there is no ink to hack here. Below, I will give yourself a convenient plan for the QL1680 ADSL MODEM network, please see: Friends have seen Figure 2, maybe ask: Can this network plan to complete the shared Internet? Don't worry, let me explain to everyone. The key is here ...
figure 2
In this scenario, an internal user access to the Internet is different: LAN users → Switch → ADSL MODEM → ISP (Internet). What is the difference than the previous program? Less a server and two network cards! The whole port of QL1680 ADSL Modem has routing functions, which can be used as a router to completely replace those soft routers. Because routing features are more stability in MODEM, there is a lot of stability, avoiding various inexplicable maintenance, configuration failures and issues of soft routing (hearing here, friends are not bright). It is so simple, put the full-to-one QL1680 to the switch any port, the hardware connection is OK. Other things make QL1680 to do it. It is also very simple to configure, as long as we set the PC's network card IP to automatic acquisition, the gateway set into an IP address of the ADSL MODEM, then starts the ADSL Modem to Dial. This will surf the Internet. Moreover, I saved a network card, which is very worthy of our pocket is not very rich. Seeing this, you may say, this program looks good, but how is the actual effect? How many machines can the QL1680 routing? If you ask, QL1680's routing is more powerful. You have to ask you all, I only know your own Internet cafes 50 machines, a 2M ADSL line, speed is fast, and users are satisfied. The last rate is significantly increased, the profits ... Hey. Friends, don't hurry up?
