Whether in schools, homes, or offices, if China Telecom blocks router sharing, the Internet access is severely blocked. The magic of a high foot, or a high person summed up the method of cracking and blocking. The following describes how to share routes restricted by China Telecom. If you have already pulled the network cable, you can try it yourself.

1. the implementation method is very simple, but two routers need to be used for two routes. Here we are an ADSL cat with a route and a TP-LInk router. If your ADSL does not have a route, let's find another one. That's the hardware requirement.

Step 1: set ADSL Broadband cat to automatic dialing to disable its DHCP function. Disable the SNMP function in the security options.

Step 2: connect the network cable on the ADSL cat to the WAN port of the router, set the IP address of the computer and the IP address of the router to a CIDR block, and enable IE (192.168.123.254) configure the vro:

Change the WAN connection type to a static IP address (note that it is not in PPPOE mode). Change the wan ip address to an IP address segment with ADSL cat, for example, 192.168.1.2 (the IP address of your ADSL cat is 192.168.1.1) and the subnet mask is 255.255.0, gateway 192.168.1.1, DNS: 202. 99. ***. ***.

2. the other method is the solution to the failure of starting the shared yundun filter/inspiration in the next shared yundun software. The reason is that the shared yundun driver is not correctly installed into the network components, the solution is as follows:

Install the shared security Software first, and restart it automatically. Then, choose "Control Panel"> "network connection"> "Local Connection", right-click "properties", and choose "Install"> "service" if you do not see ChinaStart Software.

Click "Install from disk", find the folder where you installed the shared Alibaba Cloud Security Driver, and install the file netsf with the Filter Driver character, it will be okay if you unload, plant, and install it again. You must install each machine!

How to prevent being blocked

You can download a firewall. I use Kingsoft network. After the download and installation are complete, set the security level of the network segment to the maximum and disable port 161.

Method 1:

First, make sure that you are able to access the Internet in the single-host computer. It indicates that the MAC address of the computer Nic is a valid MAC address. Go to the MSDOS mode of the system and run the ipconfig/all command to find the MAC address of the computer Nic. Example: 00-50-8D-D1-71-A7. Find a valid MAC address, ununplug the external lead from the NIC of the single-host computer, and insert the WAN port of the Broadband Router. Connect the NIC of multiple clients to the lanport of the Broadband Router. Turn on the power of the Broadband Router. Start ie on any client connected to the Broadband Router. In the address bar of IE browser, enter the IP address of this Broadband Router, http: // 192.168.1.1. Go to the Web Settings page of The vro. Click "Network Parameters" in the Left window of the configuration page and select "clone MAC address. The "clone MAC address" window appears. In the "MAC address of the current management PC" window, enter the "valid MAC address": 00-50-8D-D1-71-A7. Click Clone MAC address. The MAC address is entered in the "MAC address" window. Finally, restart the vro to make the settings take effect. In this way, the vro obtains a valid MAC address bound to the ISP. You can share the Internet with multiple computers. Note: The "clone MAC address" button for some routers is "clone mac" in English ". Appendix: Modify the MAC address of the NIC. Experience has proved that the MAC address of all computer NICs in the LAN can be modified or shared with the Internet.

Method 2:

Some broadband providers have bound MAC addresses on the authentication server to limit the number of connected users. At this point, you can first connect the computer bound with the MAC address to the lanport of the router (but the router should not connect to the Modem or the wiring provided by the ISP), and then use the MAC address cloning function of the router, copy the MAC address of the network adapter to the WAN port of the Broadband Router.

Method 3:

The "MAC address clone" function of the Broadband Router breaks through the address binding of the broadband provider to achieve Internet sharing among multiple computers.

Take TP-Link TL-R400 + small router as an example. Go to the Web Settings page of The vro from the computer with the bound MAC address, and select "Initial Settings" under "Basic settings" in the main menu ", click "modify" in the "wan interface type" column, and then select "Dynamic IP ".

After saving, return to the "Initial Settings" Page. There is a text box after the option in the "Wan MAC address" column, where the content is the MAC address of the local machine, you can modify the MAC address in the text box and enter the MAC address of the bound Nic. If you do not know the MAC address of the NIC, you can select the Clone MAC button to Clone the MAC address of the NIC of the current computer to the WAN port of the TL-R400 +. Save and restart the vro.

Note: You must select "Dynamic IP" in the "wan interface type". Otherwise, the option of modifying the MAC address and cloning MAC address of the WAN interface will not appear. If you are using other access methods, such as static IP addresses and PPPoE, you can go to the configuration page to modify the WAN type after completing the preceding settings.

How to escape detection by network Vanguard

There are two ways for ADSL to share the Internet. One is proxy and the other is address translation (NAT). Generally, the routing method is actually NAT, in fact, the principle of routing and NAT is still different. We will not discuss it here. Currently, ADSL cats generally have NAT functions. It is more economical and convenient to use its own functions to achieve Internet sharing, this article mainly discusses this method.

1. Check whether packets with the same IP address have different MAC addresses,

(2) in Windows 2000/XP, click Start → run → Enter CMD → press ENTER → enter ipconfig/all → press Enter. Alternatively, right-click the local connection icon, select the status, and click the support tab. "details" contains MAC and other important network parameters.

1. if your NIC Driver directly provides the clone MAC address function, such as the RTL8139 chip from RealTek, congratulations! Click "Start> set> Control Panel ", double-click "network and dial-up connections", right-click the NIC icon to modify the MAC address, and select "properties ". On the "General" tab, click the "configuration" button and click the "advanced" tab. In the "attribute" area, you should see a project called "Network Address" or "Locally Administered Address", click it, and under the "value" on the right, enter the MAC address value you want to specify. You must enter 12 numbers or letters consecutively. Do not enter "-". After the system is restarted, the setting will take effect (Windows 98 and Windows 2000/XP user operations are slightly different, please refer to the System Instructions)

If your NIC driver does not provide the clone MAC address function, here are some methods to find a suitable

In WinXP, most NICs can change their MAC addresses by modifying the NIC attributes in the control panel. In Device Manager, right-click the NIC icon to modify the MAC address and select the properties/Advanced tab. In the "properties" area, you can see a project called "Network Address" or another similar name. Click it and click it at the bottom of the "value" on the right, enter the MAC address to be specified. You must enter 12 hexadecimal numbers or letters consecutively. Do not enter "-". Other software that can modify MAC can be run in XP/W2K. You can search for it online.

2. SNMP (Simple Network Management Protocol) is used to discover multi-host internet access.

Some routers and ADSL cats have built-in SNMP services through scanning software (ipscan, superscan ......) after scanning, we found that port 161 is open and port 161 is the service port of SNMP (Simple Network Management Protocol). Is it the number of hosts found through the SNMP protocol, and xscan is used to scan the cat for vulnerabilities, there is a default password, which is logged on to the management interface of the cat but cannot be found to close the SNMP service. It seems that it is a backdoor, and it can be concluded that it is the number of hosts found through the SNMP protocol. In order to further confirm that an SNMP management software, ActiveSNMP, is used to view the connection status of the ADSL cat, 2 shows that the SNMP protocol can clearly identify the number of hosts accessing the Internet at the same time.
