Whether at school, home, or in the office, running into ISP blocks on router sharing can seriously hinder everyday internet access. But for every measure, there is a countermeasure, and some clever folks have worked out ways to bypass these restrictions. Below, we share several methods to crack the shared-router limits imposed by telecom providers. If you already have a network cable set up and are using a router, you can give these a try yourself.
1. The implementation is simple but requires two routers for double routing. Here, we use one ADSL modem with routing capability and one TP-Link router. If your ADSL modem does not support routing, you’ll need to find another one. That’s all the hardware required.
Step one: Set the ADSL broadband modem to auto-dial, disable its DHCP function, and turn off the SNMP function in the security options. We won’t go into the detailed process here.
Step two: Connect the network cable from the ADSL modem to the WAN port of the router. Then set the computer’s IP to be on the same network segment as the router’s IP. Open IE (mine is 192.168.123.254) to configure the router:
Change the WAN connection type to Static IP (note: not PPPoE mode). Set the WAN IP address to be on the same IP segment as the ADSL modem, e.g., 192.168.1.2 (my ADSL modem IP is 192.168.1.1), subnet mask 255.255.255.0, gateway 192.168.1.1, DNS: 202.99.***.***.
2. Another method is to download the ShareShield software. If you encounter the failure of starting the ShareShield filter/heuristic, the root cause is that the ShareShield driver was not correctly installed into the network components. Below, we introduce the solution:
First, install ShareShield, which will automatically restart your computer. Then go to Control Panel -> Network Connections -> Local Area Connection -> Right-click “Properties” -> Install -> Service. If you do not see “ChinaStart Software”,
click “Have Disk”, browse to the installation directory of ShareShield, find the “Driver” folder, and install the file “netsf”. Once “Filter Driver” appears, install it, then uninstall it, and finally install it again. That should do it! This must be done on every machine.
How to Prevent Being Blocked
You can download a firewall; I use Kingsoft Internet Security. After downloading and installing, set the firewall’s security level to the highest and close port 161.
Method 1:
First, make sure the computer used for the original internet subscription can access the internet in standalone mode. This confirms that the computer’s network card MAC address is a legitimate one. Enter the system’s MS-DOS mode, run the ipconfig /all command, and you can find the MAC address of this computer’s network card. For example: 00-50-8D-D1-71-A7. After finding the legal MAC address, unplug the incoming line from the standalone computer’s network card and plug it into the broadband router’s WAN port; connect multiple client machines’ network cards to the router’s LAN ports. Turn on the broadband router’s power. On any client machine connected to the router, launch an IE browser. In the IE address bar, type the router’s IP address, e.g., http://192.168.1.1. Enter the router’s web configuration page. Click the “Network Parameters” button in the left window of the configuration page, then select the “MAC Address Clone” button. The “MAC Address Clone” window will appear. In the “Current Management PC MAC Address” window, fill in the “legal MAC address” found earlier: 00-50-8D-D1-71-A7. Then click the “MAC Address Clone” button, and this MAC address will be filled into the “MAC Address” window. Finally, restart the router for the settings to take effect. This way, the router obtains a legitimate MAC address bound by the ISP, allowing multiple computers to share internet access. Note: On some routers, the “Clone MAC Address” button is labeled “clone mac”. Attached: Modifying the network card’s MAC address. Experience has shown that modifying the MAC addresses of all computers’ network cards on the local network can also enable shared internet access.
Method 2:
Some broadband providers bind the MAC address on the authentication server to limit the number of access users. In this case, first connect the computer with the bound MAC address to a LAN port of the router (but do not connect the router to the Modem or the ISP-provided line). Then, use the router’s MAC address cloning function to copy that network card’s MAC address to the broadband router’s WAN port.
Method 3:
Use the broadband router’s “MAC Address Clone” function to break through the provider’s address binding and enable multiple computers to share internet access.
Take the TP-Link TL-R400+ small router as an example. From the computer with the bound MAC address, enter the router’s web configuration page. Under the “Basic Settings” main menu, select “Preliminary Settings”. In the “WAN Interface Type” column, click the “Modify” button, then select “Dynamic IP”.
After saving, return to the “Preliminary Settings” page. Behind the options in the “WAN MAC Address” column, there is a text box. Its content is the current computer’s MAC address. You can directly modify this MAC address in the text box, filling in the bound network card’s MAC address here. If you are unsure of the network card’s MAC address, you can choose the “Clone MAC” button to directly clone the current computer’s network card MAC address to the TL-R400+’s WAN port. Save and restart the router for the changes to take effect.
Note: You must select “Dynamic IP” in the “WAN Interface Type” field, otherwise the options to modify the WAN interface MAC address and clone the MAC address will not appear. If you are using other connection types, such as Static IP or PPPoE, you can first complete the settings above, then re-enter the configuration interface to change the WAN type.
How to Evade Network Rogue Detection
ADSL shared internet access has two modes: proxy and Network Address Translation (NAT). The routing method people commonly refer to is actually NAT mode. There is actually a principle difference between routing and NAT, but we won’t discuss that here. Modern ADSL modems generally have NAT functionality. Using their built-in features for shared internet access is more economical and convenient. This article mainly discusses this method.
1. Check if data packets from the same IP address contain different MAC addresses.
(2) In Windows 2000/XP, click “Start” 鈫?”Run” 鈫?type “CMD” 鈫?press Enter 鈫?type “ipconfig /all” 鈫?press Enter. Alternatively, right-click the local connection icon, select Status, then click the Support tab. “Details” here contains the MAC address and other important network parameters.
1. If your network card driver directly provides a MAC address cloning function, such as the RealTek RTL8139 chip, congratulations. Click “Start 鈫?Settings 鈫?Control Panel”, double-click “Network and Dial-up Connections”, right-click the network card icon needing modification, and select “Properties”. In the “General” tab, click the “Configure” button, then click the “Advanced” tab. In the “Property” area, you should see an item called “Network Address” or “Locally Administered Address”. Click it, and under “Value” on the right, enter the MAC address value you want to assign. Enter 12 consecutive digits or letters, do not include “-” between them. The settings will take effect after a system restart (Windows 98 and Windows 2000/XP users may have slightly different steps, please refer to the system instructions).
If your network card driver does not provide a MAC address cloning function, some alternative methods are provided below. Hope you can find one that fits your situation.
Under WinXP, most network cards can change their MAC address by modifying network card properties in the Control Panel. In “Device Manager”, right-click the network card icon needing modification, and select the “
