6. Broadband router is also a kind of shared Internet equipment, similar to ADSL modem, it also has the function of "routing", which can replace the position of proxy server and become the "gateway" of client. The client uses this "gateway" to access the Internet. Moreover, most of the broadband routers also have 4-port or 5-port switches. The client only needs to plug the network cable into the switch port of the broadband router, and then simply configure it to access the Internet. Its networking mode is shown in Figure 1

Figure 1
broadband router supports the sharing of multiple Internet access modes, such as ADSL, FTTB + LAN (fiber to building + LAN to home), closed-circuit broadband (cable modem), ordinary 56kbps modem dial-up Internet access, etc. However, for ADSL access mode, it only supports Ethernet ADSL modem

next, we will still take Windows 2000 platform as the foundation, and take ASUS aam600ev non routing Ethernet ADSL modem and tp link tl-r400 broadband router as examples to explain how broadband Routers share ADSL (other brands of broadband routers will have different setting interfaces, However, the places and contents to be set are almost the same

first of all, make sure that ADSL modem works normally, that is, we can access the Internet through it. Then, we cut off the power supply of the computer and ADSL modem and connect the tl-r400 broadband router

Figure 2
tl-r400 broadband router is shown in Figure 2. It is a shared Internet device specially developed for home users and small offices. It integrates 4-port 10 / 100Mbps switch, which is used to connect user computers that need internet access. The WAN port on the back panel is used to connect ADSL modem and other network access devices. First, we connect the straight through twisted pair supplied with aam600ev to the RJ-45 port of modem and the WAN port of tl-r400 (originally this straight through twisted pair is used to connect modem and computer), and then connect the RJ-45 port of network card and the LAN port of tl-r400. After connecting, connect the modem and tl-r400, and turn on the computer

I. configuration of broadband router

now, we need to simply configure tl-r400 broadband router, so that it can replace the computer for automatic dialing

Figure 3
like most Ethernet ADSL modems, tl-r400 broadband router also has an IP address and adopts Web page management mode. We can enter it in the address bar of IE browser“ http://xxx.xxx.xxx.xxx ”Enter the management page to set it. Tl-r400 factory default IP address is "192.168.123.254", subnet mask is "255.255.255.0". We should pay attention to, now directly in the computer's IE browser address bar input“ http://192.168.123.254 ”Is unable to access the management page, the reason is very simple: IP address to be in the same network segment can be accessed. So we first need to modify the IP address of the local connection of the computer

Figure 4
right click the "network neighborhood" icon on the system desktop, and select the "properties" item in the pop-up shortcut menu to open the "network and dial up connection" dialog box. Select "local connection" in the dialog box, and then right-click to select "properties" in the pop-up menu to enter the "local connection properties" dialog box. In this dialog box, select "Internet Protocol (TCP / IP)" and click "properties" to enter the "TCP / IP properties" dialog box. In this dialog box, set the IP address to "192.168.123. X" (x is a natural number from 1 to 253) (for example, "192.168.123.200" in this example), and set the gateway to "192.168.123.254" (Figure 3). After "OK" for two consecutive times, the setting takes effect immediately. Now, we can enter it in the IE address bar“ http://192.168.123.254 ”Enter the management page of tl-r400

Figure 5
enter the default password "admin" in the login box on the left side of the login page to enter the management page. In the menu on the left side of the management page, select "primary setup", and the dialog box as shown in Figure 4 will appear. In this dialog box, the default IP address and WAN type of tl-r400 are displayed, and the default is "dynamic IP address". Click the "change" button to enter the dialog box shown in Figure 5. In this dialog box, we need to click "PPP over Ethernet" to change the WAN type to "PPPoE" (point-to-point protocol on local area network). This is because ADSL dialing uses this protocol. Click "save" to enter the next dialog box. Here, we need to set the ADSL account and password (that is, the ADSL user name and password provided by ISP). After that, the task of dialing will be handed over to tl-r400. After filling in, we need to save the settings. But wait!! We think carefully about the process of data transmission from the Internet to the user's computer, which is from Internet → ADSL modem → broadband router → local machine. As we have seen before, in order to access the broadband router, we must unify the IP address segment of the local connection with the IP address segment of the broadband router, Furthermore, the default private IP address of ADSL modem -- ASUS aam600ev Ethernet ADSL modem is "192.168.1.1" (the default IP address of most Ethernet ADSL modems is "192.168.1.1"), and the subnet mask is "255.255.255.0". Obviously, it is not in the same network segment as "192.168.254. X", that is to say, tl-r400 can not access ADSL modem and data can not be transmitted. Only when the IP address segments of ADSL modem, broadband router and local connection are unified, can mutual access and data transmission be realized! Therefore, we also need to modify the IP address of tl-r400. We suggest that the IP address be modified to the same network segment as ADSL modem, such as "192.168.1.2" and "255.255.255.0" in this example (Figure 6). Finally, click "save" to save the settings, and click "reboot" to restart tl-r400 broadband router immediately to make the settings take effect

Figure 6
2. Client configuration

when tl-r400 is restarted, a dialog box with the words "system is restarted please reconnect manually" will pop up. Let's reconnect the management page. At this time, you enter it in the IE address bar again“ http://192.168.123.254 ”The management page can no longer be accessed because the IP address segment of tl-r400 has been modified and is not in the same segment as the IP address of the existing local connection. So now we need to reconfigure the client

Figure 7
enter the dialog box shown in Figure 4. Here, change the IP address to "192.168.1. X" (x is a natural number from 3 to 255) (in this case, "192.168.1.3"), and the subnet mask is still "255.255.255.0". As tl-r400 now replaces the previous proxy server and acts as a "gateway", here we set the "gateway" to the IP address of tl-r400 "192.168.1.2". Since the "gateway" sharing mode is adopted, the DNS server of the client should also point to the "gateway", that is, "192.168.1.2" (Figure 7) (we have mentioned this point when using Sygate sharing Networking)< Now, the private IP addresses of ADSL modem, broadband router and local connection are all in the same network segment, and data transmission can be realized
enter in the IE address bar“ http://192.168.1.2 ”Then enter the management password to enter the tl-r400 management page, and click the "connect" button in the lower right corner to make a dial-up connection. After waiting for about 5 seconds, the connection is successful. At the same time, tl-r400 will display the obtained public IP address, ISP DNS server address and other information (Figure 8)

figure 8
now the client can access the Internet. Open IE and enter the web address - go

when you want to access the Internet in the future, as long as you turn on the power of ADSL modem and tl-r400, tl-r400 will automatically dial and connect to the Internet. At this time, after the computer login, you can directly access the Internet, without any additional operation. If you don't want to surf the Internet, turn off the tl-r400
tl-r400 supports four computers sharing the Internet. If there are more than four computers, a hub (or switch) can be added. The networking mode is shown in Figure 9

[advantages and disadvantages of routing ADSL sharing]

some readers may say, I don't want to share the Internet, routing doesn't matter. It's true that it doesn't seem to be very important for a single Internet user whether to route or not, but for users who need to share, there is a more intuitive difference between routing and not. Finally, let's summarize the advantages and disadvantages of routing mode. You can decide whether to use routing mode according to your actual situation

advantages

1. The network is convenient, and does not need a single computer as a proxy server, which can rece the loss and save electricity

2. After setting once, the computer will be able to access the Internet when it is turned on, so it is very convenient and easy to dial without installing dialing software

3. All computers are not exposed to the public network, which is relatively safe. If the firewall function of broadband router is turned on, the Internet security will be further guaranteed

disadvantages

1. All computers have no public IP address, and the exposed ones are routing ADSL modems or broadband routers. Some applications need public IP address (such as peer-to-peer information sharing, such as P2P; All kinds of servers (such as streaming media server, mail server, etc.) need port mapping. Although most ADSL modems and broadband routers support port mapping, they still need to be set separately, which is not so convenient

2. The number of shared computers supported is limited, which is not comparable to the sharing mode of single proxy server / gateway computer. The general routing ADSL modem can stably support 5-12 computers, while the broadband router that can stably support 60 computers (without switch, and need to buy switch or hub separately) needs more than 2000 yuan, and the price is not cheap.
