What Is a Fiber-Optic Router?

In order for the router to dial automatically, we also need to integrate the ADSL account into the router. Click the "Home" tab at the top, and then click "WAN" to change. At the PPPoverEthernet, you will see the place where the ADSL account is set. Enter the ADSL account and password you applied for and save the settings. Now go to the "System Information" section of the "System Status" tab to check the network status. On the WAN side, you can clearly see the network information obtained by ADSL dial-up.

Fiber router settings: prevent messy bt

By default, all computers connected to the router are protected, that is, they are in the internal network, and the use of p2p software such as bt will be affected to some extent. We can use the "DMZ" in the "Advanced Settings" tab to set the announced host. The host set here is exposed to the network. On the one hand, you can use bt to download software and set up IIS and FTP server without any care. On the other hand, it is also exposed to hackers and viruses. Therefore, the security of this computer must be certain. Be good. (It is very unwise to announce the host just to use p2p software such as bt. In fact, we can use the upnp function to solve the problem that the p2p software cannot be used on the internal network. The method is to click "Tools" on the router settings interface "Other items" under the label, and then set upnp to "Enable".) Enter the filter tab in the broadband router settings interface, we can filter a variety of items on the source and address of the datagram, including IP Address, url information, mac address, and area information. Set "Activate" IP address filtering, and then enter the IP address in the IP address range, such as 192.168.0.111. The "Port range" is actually filled in the port information. Since bt download uses ports 6881 to 6889, we Filter it here. Select "TCP" for "Protocol", and set the time when the filtering takes effect (the prohibition time depends on the actual situation).

Fiber router settings: service and security

If the computer is exposed to the internet, hackers and viruses may use vulnerabilities to attack the computer. In fact, we can solve this problem by setting up a virtual server. Log in to the Broadband Router Settings interface. Select the Virtual Server tab in the advanced settings interface. Activate the virtual server settings and enter the relevant virtual server information. For example, if we want to allow the computer 192.168.0.112 to provide ftp service, but want to let other ports be protected by the router, we can just virtualize the ftp service. The personal IP address is set to 192.168.0.112, the protocol mode is tcp (ftp service uses tcp protocol), and personal port 21 (ftp uses port 21). In addition, you can set the time period for the virtual service to take effect at "Arrange".

Fiber router setup: common hardware connection methods

1.Telephone line-> ADSLMODEM-> Computer

2.Twisted pair (Ethernet cable)-> Computer

3.Cable TV (coaxial cable)-> CableMODEM-> Computer

4.Fiber-> Optical Converter-> Proxy Server-> PC

ADSL / VDSLPPPoE: Run a third-party dial-up software such as Enternet300 or WinXP's own dial-up program on your computer, fill in the account number and password provided by your ISP, and dial the number before going online each time;

Or your ADSLMODEM has the routing function enabled, filled in the account and password provided by the ISP, and the dialing action is left to the MODEM; (this broadband access method is typical, such as the "network express" provided by China Southern Telecom)

Static IP: Fixed IP address, subnet mask, default gateway, DNS provided by your ISP;

Dynamic IP: The computer's TCP / IP property is set to "Obtain an IP address automatically", and you can access the Internet every time you start the computer; (This broadband access method is typical, such as Shenzhen "Tianwei Video")

802.1X + static IP: ISP provides fixed IP address, special dialing software, account and password;

802.1X + dynamic IP: ISP provides special dialing software, account and password;

WEB authentication: before each time you go online, open the IE browser, go to the homepage designated by your ISP, fill in the username and password provided by your ISP, and then perform other online operations after passing the authentication;

The content of the optical router settings is introduced here for you. The connection authentication methods mentioned above are only some broadband access methods with high penetration rates. Of course, there are other topological connections and authentication methods; therefore, when you cannot When you are sure of your broadband method, it is best to consult your ISP: Is your IP address static or dynamic? Is the protocol used for authentication PPPoE, 802.1X, or WEB authentication? When the above two questions are answered, the router can be configured. ^[1]
