Practice: how to configure routes to achieve multi-PC Internet sharing (group chart) (1)

Some people may say that a network administrator will configure a route to achieve multi-PC Internet sharing. Although this is an absolute point, it is not biased. Theoretically, a network administrator must first learn these things. Of course, it is common to learn to write and forget words, and the details of Route configuration will inevitably be forgotten. This article will detail every step you need to take to configure a route for multi-PC Internet sharing. I hope you will be able to wake up when you forget to write a word.

The following content of this document mainly describes the following parts:

1. Collect and judge the information to prepare for configuring the router;

2. Enter the vro management interface and configure the vro;

3. Simple troubleshooting during configuration;

Let's get started and get started!

1. Preparations before configuring the vroIf you have a clear connection method, you can directly jump );

The first thing to confirm is what your "Broadband Access Method" is like?

Of course, the simplest way is to give a call to your ISP Internet Service Provider. You can also make a quick judgment by using the previous network connection method of the router you purchased.

Common Hardware connection methods include the following:

1) Telephone Line> adsl modem> Computer

2), twisted pair ethernet cable)-> Computer

3), Cable TV coaxial Cable)-> Cable MODEM-> Computer

4), optical fiber-> photoelectric converter-> Proxy Server-> PC

ADSL/VDSL PPPoE: A computer runs a third-party dialing software such as Enternet300 or a dialing program provided by WinXP. Fill in the account and password provided by the ISP, and dial the number before accessing the Internet each time; alternatively, your adsl modem has enabled the routing function, fills in the account and password provided by the ISP, and sends the dialing action to the MODEM; this broadband access method is typical, such as the "Network Express" provided by China Southern Telecom ")

Static IP: the ISP provides you with a fixed IP address, subnet mask, default gateway, and DNS;

Dynamic IP: The TCP/IP attribute of the computer is set to "automatically obtain IP addresses", and the computer can access the Internet each time it starts. This broadband access method is typical for Shenzhen "tianwei video ")

802.1X + static IP: the ISP provides fixed IP addresses, dedicated dialing software, accounts, and passwords;

802.1X + Dynamic IP: the ISP provides dedicated dialing software, accounts, and passwords;

WEB Authentication: before accessing the internet, open the Internet Explorer, specify the home page of the ISP, enter the user name and password provided by the ISP, and perform other online operations only after the authentication; the above blacklist is your broadband access method, but the access method and hardware connection method are not fixed)

The above mentioned connection authentication methods are only some of the broadband access methods with high penetration rate, and of course there will be other topological connections and authentication methods; therefore, if you are not sure about your bandwidth, you 'd better ask your ISP: is the IP address static or dynamic? Are the protocols used for authentication PPPoE, 802.1X, or WEB Authentication? With the answers to the two questions above, you can configure the router;

2. How to enter the vro management interface?

First refer to the above figure in the user manual, connect adsl modem, router, computer; TL-R4XX series router management address factory default: IP Address: 192. 168. 1. 1. subnet mask: 255. 255. 255. 0 TL-R400 and TL-R400 + two management addresses default: 192. 168. 123. 254, subnet mask: 255. 255. 255. 0) Use a network cable to connect the LAN port of the router to the computer network card. Because the Ethernet port on the router has a polar auto-flip function, you can use a direct line or cross line to connect the network cable, it is necessary to ensure that the production of the cable crystal head is reliable and stable, the crystal head copper is not rusted.

Right-click "Network neighbors" on the desktop and select "properties". In the displayed window, double-click "Local Connection" and click "properties ", find "Internet protocol TCP/IP)" and double-click the "Internet protocol TCP/IP) properties" window. In this window, select "Use the following IP Address ", then fill in the corresponding location:

IP Address: 192. 168. 1. XX range: 2-254 ),

Subnet Mask: 255. 255. 255. 0,

Default Gateway: 192. 168. 1. 1. After filling in, click "OK" twice;

The "Internet protocol TCP/IP) properties" window is as follows:
