双路由器方法解决网通封锁

双路由器方法解决网通封锁 The following analysis I try to introduce in plain, flowing and concise language, make sure that non-computer professionals can also read it. In theory and engineering, each network has the world's only address, the MAC, which is a binary number of 48 bits. When we dialed the Internet through a router, the netcom's router would assign us a router with an IP address. In order for each packet to quickly find a computer that initiates data requests, the router tends to encapsulate the MAC into the packet. At this moment, netcom, through "international network", "trade winds" type of scanning software, monitoring each IP address data request, once found a IP data request contains two or more MAC address, it will block the IP. How do you block IP? You can't block IP addresses first, because most users' IP addresses are temporarily allocated; Second, can't block account, because once the blocked account, after an hour unblock is the technical difficulties, and netcom will also be at risk in violation of the agreement of the law. What exactly does netcom do? We found that even blocked the router, we still can on the qq, you can use to download emule exchanges sources, which means neither blockade IP netcom, also have no closed accounts, also not all block TCP/IP port. So, they can only block the port that the browser needs, blocking the DNS. That's the crux of the problem. Netcom weighed costs and benefits, minimized the cost of the blockade and blocked most of the unknowledgeable users. Companies are always maximizing the benefits, and blocking out blocks is only a means of doing things that they can't do without cost. By upgrading the router firmware, avoid blockade, principle is router changed the way of packaging, shielding the MAC information in the packet, for the wide area network, see is the router's MAC. This is the perfect way to do it. However, as mentioned above, not every router can find firmware that can escape the blockade. In fact, routers are already under pressure from netcom and telecoms. The first place to block a router in China is xuzhou, which works well. So netcom, telecom began to promote experience. Then the tp-link developed the firmware that was able to evade blocking to the official website. However, the obvious eye will find that the blocked firmware LINK disappears quickly on tp-link's official website. Why is that? We can't say what we don't know, but we can still make a bold guess: netcom and telecom are putting pressure on tp-link. Perhaps netcom and telecom knew that blocking routers was not legal, and they put pressure on tp-link through the ministry of labor. Tp-link can ignore netcom and telecom, but he can't ignore the production department. For the ministry of industry, tp-link is only a baby girl, and netcom and telecom are the first blood. Tp-link is a bold and dare not to offend the production department. As a result, we will find that many routers and manufacturers are no longer offering downloadable services that can evade blocking. Is there no other way to solve Shared problems by upgrading firmware? There is. Not to upgrade the firmware to avoid blocking method are many, but we can divided them into two categories: one is to install the software, but modify the network card MAC address, 3 it is pair of routers. I'll introduce you. The first category, by installing software, either provides proxy services to each other, or changes the packaging of packets. There are a lot of such software, such as Sygate, WinGate, Windows, etc., etc. Rummy thinks the Shared divine shield is stable. There is a lot of information available online, and rummy is no longer talking. This type of approach, in general, requires users to have simple computer knowledge, which is difficult to set up. And it has a certain effect on the speed of the Internet, and if the user is using P2P software, the overall transmission efficiency of the network will be greatly affected. Once the reinstall system, or the agent software problem, will not be able to go online. This method, in general, is not stable. Second, modify the MAC address. Change the physical address of network card, need very professional knowledge. With the exception of reatek8139, the network CARDS for other chips, even professionals, are hard to modify. The average user can only modify the MAC of the network through the operating system or the relevant software, making all the network CARDS use the router's MAC. This type of approach is also unstable. Reloading systems or software problems can also lead to the inability to access the Internet. Both of these methods are theoretically possible. But in general, the network is unstable, the setting is more complicated, and the limiting factor is more, and it is easy to fail. Is there a way to do it once and for all? No matter how the netcom escalates the "network spigot", no matter how the client reinstalls the system, does not affect the sharing? That's what I'm going to focus on. This is the two-router blocking method. This method, without any technical requirements, does not need to install any software, or even set parameters, once and for all. What is a dual router? What is a dual router? Let's assume that your broadband cat doesn't have the routing function (in fact, the broadband cat that netcom gives has almost no routing function). We buy two routers, a method according to the normal cat and broadband connections, dial-up parameters have been set, set the LAN port IP to "192.168.1.2 instead -- 192.168.1.255", subnet mask 255.255.255.0, as usual. A line is then pulled from any LAN port of this route to access the WAN port of a router. Then set this router to fixed IP: "192.168.1.2". Note: the LAN mouth is set to "192.0.0.0.0.0.255" and the subnet mask is set to "255.0.0.0". The knowledgeable person knows that as long as the network segment is different, the IP address is actually arbitrary. Then, connect all the computers that you need to share to the second router. You will find that netcom, telecom is a big deal and can't be blocked. What is the principle? The router is actually a dedicated computer, which is exactly the same as the host in the network. The first router ACTS as the dial-up server already, also ACTS as a proxy server, packets after two encapsulation, "international network" is to have the immortal wisdom can't see. Rummy strongly recommend using this method, the method is simple to set up and maintenance is simple, does not fear the netcom upgrade scanning software, does not fear the client reshipment system, customers don't even need to set any parameters, bt can use, is the best solution once and for all
