How to Create a LAN through a vro

Before creating a vro, review the basic knowledge of the vro.

The networking methods are described as follows:

Method 1:A hub is one of the most widely used network devices.

However, because all ports of the hub share the bandwidth of the hub, the more computers you connect to, the slower the network speed. Because, as the price of vswitches and vrouters decreases, the hubs have been abandoned in Small and Medium network construction solutions.

Method 2:A vswitch is also one of the most widely used network devices. It is also used to build a network with a star topology.

In terms of appearance, the vswitch is almost the same as the hub. However, because the switch adopts the exchange technology, its performance is much better than that of the hub. However, considering the need for Internet sharing, because the vswitch and ADSLMODEM provided by most broadband service providers do not support the ADSL dial-up function, they are not commonly used in the networking of Internet sharing at home.

Method 3:Using a Broadband Router to share broadband Internet access is currently the most convenient solution.

The principle of a Broadband Router is similar to that of a proxy server. If you purchase a Broadband Router, you do not need to buy a switch or hub. By inserting the network cable of each computer into the router port and using the automatic dialing function of the Broadband Router, you can easily achieve Internet sharing, saving the trouble of dialing each time you start up. In addition, when we build a large network, too many hosts in the same network will generate too much broadcast traffic, thus reducing network performance.

To improve performance and reduce broadcast traffic, we can use routers to separate networks into different subnets. Vrouters can isolate broadcasts between networks so that broadcasts from one subnet are not forwarded to another subnet, thus improving the performance of each subnet. Of course, for some large Internet cafes with many machines, campus networks, and enterprise networks, the performance requirements for routers are high. General routers cannot cope with such problems. In this situation, vrouters and vswitches are a good choice for cost effectiveness.

Vro Basic settings

Step 1: we must first connect the power of each hardware device. Second, insert the telephone LINE into the LINE port of the modem, and use an Ethernet cable (non-crossover) to connect the Ethernet port of the modem to the WAN port of the router. Then, use an ethernet cable (non-crossover) to connect the LAN port of the router (either of the interfaces provided) to the UpLink port of the hub or switch. Of course, if you have few machines, you can also directly use an ethernet cable (non-crossover) to connect the LAN port of the router to the computer's Nic.

Step 2: Start setting. Set the IP address of each computer to be automatically obtained, the DNS address is also set to be obtained by force, and the gateway is empty. Then, run the ipconfig command at the DOS prompt. If the IP address such as 192.168.1X is obtained and the gateway is 192.168.11, the router works normally. If you cannot obtain the IP address, you have to enter the lnternet protocol attribute of your computer for manual settings. Here, we take the Linksys BEFWllS4 router as an example: assign an IP address. Because the default IP address of the Linksys BEFWllS4 router is 192.168.1.1, therefore, you must set the IP address of a local computer, such as PC_A, to 192.168.1.X (the value of X is between 2 and), the gateway address to 192.168.1.1, And the subnet mask to 255.255.255.0. In this way, you ensure that the vro and PC_A are in the same network segment and are ready to log on to ADSL.

TIPS: You need to know the DNS server address of the network service provider in advance. Otherwise, you only connect your computer through a vro and cannot share the internet.

Because the Linksys BEFWllS4 router supports modifying its configuration through the Web, as long as you open IE browser on PC_A and enter 192.168.1.1 in the address bar, the Login Dialog Box will pop up immediately, enter the user name and password respectively in the user and password blocks, and then confirm to log on to the vro Management page. The "WAN connection mode" option is displayed in the settings menu, this is the most important step to configure the WAN port working mode of lnterne.

Assume that your bandwidth access method is ADSLPPPoE, select "WAN port connection type" as "PPPoE", fill in "Internet account", "Internet password ", if you are a monthly subscription user, select "Automatic Connection" as the connection mode ", click "save" to complete the configuration. The "Internet password" box contains several more passwords, this is a router dedicated for security. Then, click "running status" in the left column of the management interface. On the "running status" page, "WAN port attribute ", at the beginning, the corresponding IP address subnet mask, default gateway, DNS server, and other addresses are not displayed. This indicates that the vro is in the dialing process and the corresponding information appears after these addresses, fill in the DNS server address in the "lnternet protocol TCP/IP)" page to determine the corresponding location, the basic settings are complete, if there is no serious problem, you can surf!

If your service provider gives you a Static IP address, select Static IP from the drop-down list. Fill in the IP address, subnet mask, default gateway, and DNS server. After the settings are complete, enter any URL in the right IE address bar to bring up the authentication dialog box, enter the username and password provided by the network service provider.

TIPS: common default vro addresses, accounts, and passwords

The default IP address of the Huawei router is http: // 192.168.1.1. The admin password is blank.

TP-LINK router default IP http: // 192.168.1.1 username admin password admin

KINGNET router default IP http: // 192.168.1.1 username admin password admin

D-LINK you flood router default IP http: // 192.168.1.1 username admin password is blank

ZTE 831ADSL terminal default IP http: // 192.168.1.1 username ZXDSL password ZXDSL

Default IP address of the alicat 511 ADSL terminal http: // 10.0.0.138 username root Password orroot

Huawei SmartAX MT800 ADSL terminal default IP address 192.168.1.1 username admin password admin

Poor website Filtering

The Internet is a double-edged sword. There are both good and disturbing aspects for parents. That is, bad information may make our next generation poisoned and the Internet may attract them deeply, they are trapped in it and forget to learn and rest. The only good way to prevent the last adult from accessing bad information is to isolate bad information.

The essence of our online operations is that computers constantly send request packets. These request packets must contain some parameters, such as: IP, destination IP, source port, destination port, and so on. The router restricts these parameters to control the different Internet access permissions of computers on the internal LAN, many vrouters have already added the website filtering function. You only need to use some functions to input the URLs of poor websites into the filter form, which can effectively prevent users from logging on to these websites. For example, the current aolympus NK BR204/BR304 Broadband Router, TP-link TL-FWRll00 has this function. Take aolympus br204 as an example. You only need to log on to the br204/br304 WEB page, go to the "" "site filtering page, and click" "·". The site filtering configuration page appears, enter the website address of the website you want to disable.

Restrict IP addresses

After configuring a vro, it means that all the machines in the network can access the Internet, but how can we better control these computers? For network administrators, uncontrolled computers often cause security problems. Some users will bring their own computer into the infected computer. This requires further vro configuration.

Generally, a vro provides an IP address segment filtering function. You can set an IP segment based on the number of computers in the network, for example, you can enter the IP addresses 192.168.1.10-192.168.1.20 in the filter list. Next, we will still use the Linksys BEFWll4 router as an example. after entering the vro management interface, go to the "advanced)" filter Filers) subitem, enter the IP segment to be restricted in the IP address filtering range. Click agree. Of course, if you only restrict the IP address of a machine, you can use the "MAC address filtering" function in the route. On the "MAC address filtering" Page, enter the MAC address of the machine Nic to be restricted, and click agree.

Have you learned how to set up a vro to create a lan? This is a very practical technique. It can help you both in your work and life. I hope you can understand it.
