I like to download the movies from the Internet, I believe that this thing will not be unfamiliar, but many people find that their download speed is not imagined, it is basically more than FTP's normal download speed, watching friends to boast their own The speed is hundredk and even hundreds of hundred k, and your own download speed is still in a few k more than a dozen K, and the heart is really uncomfortable. In fact, to make BT downloads quickly, as long as you do some related settings in your computer, the author will discuss with you how to make it try to make the outside network and the intranet. The user can reach the highest download speed when using BT download, so that our BT download is also mad.
Let BT download speed mad
First, put the pulse again
Second, public network users open the download port
Third, the intranet user is a port mapping
Fourth, solve the method of ISP BT port
First, put the pulse again
In fact, the speed of the BT download is the key to the computer you can download. The computer can be directly connected to the Internet. The direct connection here is that your computer has "legal identity" on the Internet, that is, legal IP Address (public IP address). After the computer has obtained the public network IP, other users on the Internet can communicate directly with you. In accordance with the principle of BT download, everyone can pass the data directly to you, of course, the speed is fast. Users like ADSL dial-up access methods, if the computer is manually dialing by configuring the Modem into a bridge mode, the acquired IP is a public IP, and some ISPs are also allocated to the LAN access method. Public online users general BT download speed even if only one seed is basically able to download the speed limit, some readers will ask, my computer acquired IP is a public network IP, but why BT download speed is still as slow. Don't worry, then let's take a look at your computer BT download software port.
Take BitTorrent Plus! S-5.8.7 Plus! 3.5 Final as an example, the BT default port is 8881-8999. BT software seems to have software and websites with no dedicated test port (I have not found anyway), but we can use the eDonkey test page to test the port, enter _test "> http://www. -teedonkeynetwork.com/connection_test This page, enter 8881, then press "TEST" to see the status of the BT download port. As shown in Figure 1 below.
Depending on the port of the port, three different results are returned: the port is sealed, the port is open but not used, and the port is open and is already in use. Different status are as follows.
1. If the prompt shown in Figure 2 is displayed, the port used by the BT download software is blocked or installed in the _blank "> firewall, _blank"> firewall to prevent the Internet to access this port.
Figure 2: Port is not open
2. If the prompt is displayed as shown in Figure 3, the port of the BT download software is open, and the 8881 port is being used by the BT download software used.
Figure 3: Open port and use
3. If the prompt is displayed as shown in Figure 4, the port of the BT download software is also open, but the 8881 port is not used by the software in the computer.
Figure 4: Port opening but not used
Other ports used by the BT download software can also be tested one by one by one by one. If you can't access the above website, I will introduce you to the eDonkey page of the test port, open http://www.preinheimer.com/cgi-bin/connectiontest/connectiontest2.cgi, enter 8881 in the input box 8881 After pressing "Test", you can start testing. As shown in Figure 5 below.
Figure 5: In the eDonkey page test port
If the content shown below is displayed, it is also indicating that your download port is blocked or _blank "> The firewall is blocked.
After testing the use of ports, if your BT download port is open, and the software can also use it, it is very unhappy, it is likely that the seed is the reason or downloads too little user, or the route, etc. The reason is caused. According to the reason, if it is shown in Fig. 2, Fig. 3, as long as there is a seed and a suitable user's download speed, the limit value can be reached. Let's take a look at how _blank "> firewall blocks BT download.
Second, public network users open the download port
In fact, as long as it is an IP user who has a public network, your machine is a legitimate host on the Internet. Anyone can contact you directly without having to convert anything. Why is some public IP users, his BT download speed is still so slow? This is generally because the computer is installed _blank "> Firewall, basically in the default _BLANK"> The default setting from the firewall software is to block other users from the Internet, you can't receive it. The data sent by others is of course not fast. There is a way to close _blank "> firewall, so the speed of BT download is fast, but this will lose the minimum protection of the computer, and the security is reduced. If BT is downloaded, it is necessary to use _blank "> The firewall is guaranteed to ensure that the _blank"> firewall software correctly opens the external monitor port of the BT, thinking BT can download high-speed, just set the parameters correctly, open the port, how to open it in detail below _ BLANK> BT download port of the firewall.
Self-brought _blank "> firewall function in Windows XP, many users who have installed Windows XP open this feature, maybe, your BT download speed is the" wall "blocked outside. In addition to the _blank "> Firewall, many users may be installed for other majors _blank"> firewall. Taking XP comes with _blank "> firewall and day network _blank"> firewall as an example, Of course, other types of _blank "> firewall software can refer to the settings, here is different.
1. Open the BT download port in the ICF of Windows XP:
ICF is the abbreviation of "Internet Connection Firewall", which is the Internet connection _blank "> firewall .ICF is built between your computer and the Internet, which allows you to request data, and hinder you did not request packets, A package-based _blank "> firewall. The use of BT is sometimes due to the block of ICF, causing the connection without SEED or packet delay to reduce the download speed. So we need to set the ports used in the ICF not to block the ports used.
Right click on "Online Neighbors", select "Properties" in the pop-up menu, pop up the "Network Connection" window Right-click on the Internet, select "Properties" in the pop-up menu, pop up the Local Connect Properties window, select where The Advanced tab, click the "Settings" button under the window, pop up the Advanced Settings window. This page is some common network services. Now we have to add a new BT service, click the "Add" button below, pop up the Service Settings window, as shown in Figure 7 below.
In this window, you can fill some casually, "The Name or IP Address of the Computer Holding this Service on your network" column can be filled in the IP address or machine name of your machine. (If I fill this name WinXP), "The external port number of this server" is filled in 8881, "This server's external port number" is also filled in 8881, don't forget to select the TCP protocol and press, "OK" I.e. This adds a "BT" service in the "Services" field in the Advanced Settings page, as shown in Figure 8 below. This service is open is the 8881 port, and you can create another port that opens the BT download software.
Now our BT can pass all in the ICF.
2, in other professional _blank "> open BT download ports in the firewall:
There are no ICFs in many computers, but there are other majors _blank "> firewalls. Below with common Tiannan Personal _BLANK"> Firewall 2.5.0 as an example, how to set up open BT download port, other _BLANK> The firewall can refer to the settings.
Click the "Custom IP Rules" button of the Tianwang. Click the "Add Rules" button in the Custom IP Rules page, which will pop up the "IP Rules Modify" window, as shown in Figure 9 below.
In the "Name" column, you can fill in casually, fill in some brief description of the top name in "Description", you can fill in it. "Packet Direction" column selection "Receive or Send", select "any address" in the "Other IP Address", then select the "TCP" page, fill in "from 8881 to 8999" in the "local port" column " In the "TCP flag bit" column, check the "SYN" project, pay attention, don't forget to "pass" in "When you meet the above conditions" column, the default option is intercepted, this can be with our hope In contrast, other items may not be changed, then determine. Now in the Custom IP Rules page, an "BT" rule in the Tianwang is added. Check it up in front, then click the "Save Rule" icon above, everything OK. See Figure 10 below.
How, after the above settings in your computer, readers who have public IPs are not much faster, and I am so fast.
Second, the intranet user is a port mapping
In addition to public network users, many people are online by local area network, namely the intranet user. The internal network user is online through the agent or NAT mode. The IP address of the Internet is the reserved address on the Internet, and the retention address has three forms: 10.xxx, 172.16.xx to 172.31.xx, 192.168.xx, If everyone sees that the IP address of the machine is mentioned in these three forms, it will be undoubtedly in the intranet. The intranet user speed will be very slow, because in the internal network, the external network can only see your gateway address, the request can only be initiated by you, if the other party is also in the Internet, he has no way to pass it. Things, then you can't exchange files. In this way, you lose some download sources, and the speed may be slower.
Below, three common intranet users: Internet access and using routing modem dial-up network through proxy servers (Windows Connection Sharing, Sygate, Wingate, WinProxy, CcProxy, etc.) Realize the speed of the BT download. Because the machine's machine is out of a public IP address, you must pass the port mapping, NAT or virtual servers to connect the external network directly to the intranet machine, otherwise the external network user is seen. Your gateway. That is, it is necessary to pass the setting, the machine located in the intranet is transparently mapped to the Internet, and the user connects the internal web machine, this machine is also like a legal host on the Internet. 1, proxy server
Many Internet cafes or small businesses, organs, etc., all apply one or more internet lines at the ISP, with a dedicated proxy server, install the corresponding agent or gateway software on the proxy server, and assign the client DHCP The IP address or specifies a fixed IP address to provide Internet services to users within the LAN. We must increase port mapping on the proxy server to increase BT download speed.
● If your server is a network sharing connection comes with Windows, the setting is very simple. We share with Windows 2000 Internet connection sharing as an example.
Press the right button on your shared connection, select "Properties", press the "Setting" button, the system will pop up, and then select the "Add" button in the Service page, pop up the setting as shown in Figure 11 below window.
On this page, the name can be filled in (such as BT), "Services Port Number" to fill in 8881, check the TCP, "Dedicated Network Server Computer Name or Address" to fill in the BT download machine Name or IP address, then press "OK" to save. Use the same method to increase the image of other ports, and pass them to the computer you start specified.
● Use dedicated port mapping software
The software that can be used is: Portmap, WinRoute Pro, PortTunnel, etc. Examples are illustrated by PortMap V1.6. Portmap v1.6 is a small green software that is very simple. If you use other port mapping tools, you can try it. The setting method is: Run Portmap V1.6, click the "Add" button, pop up the "Add / Modify Port Mapping" window. As shown in Figure 12 below.
Enter (such as btport) in the name, fill in the IP address you want to use for BT downloads in the "Input IP" column (or select "Any IP" to put the client's entire network segment Adding into the way), enter 8881 in the "Input Port" field, "Output IP" inputs the public IP of the mobile phone network, input 8881 (the input port and output port), other settings you can Different settings are made as appropriate. This setting is completed, and then the startup that is just set up will be OK after confirmation. Use the same way to add and start the other ports used by the BT download software.
I don't know the friend of my own proxy server IP address. If the proxy server is Windows 98, running WiniPCFG on the server to display its public network IP. If you are Windows 2000 / XP, you can find the iPConfig / ALL to find the public you get your server. Network IP.
Note: Be sure to make settings or ports such as WinRoute Pro, PortTunnel, Portmap on the proxy server for NAT settings or port mappings. I often hear some friends asked, I have installed these software on my machine, and have the correct setting, how to download the speed is still the same. In fact, it is all operating on the client, of course, is not. Tip: Port mapping is similar to the concept of "function" in math, is to map the gateway port of the shared Internet server to a client port in the LAN, so that the internal network users can access their own machines through port mapping. .
2, route MODEM automatic dialing network
Many users are internet access by using routing modem automatic dialing. Multiple clients and Asal Modem are connected to a switch or hub, or a machine is connected directly to the NIC and the ADSL MODEM's LAN port with the cross line. ADSL MODEM generally has a PPPoE dial function. After the settings are set correctly, Modem power is automatically dialing to get the IP address of the public network (ADSL MODEM settings will not be detailed here, you can refer to the relevant information). The IP address obtained by the client is the retention address on the Internet, and the retention address can be as previously described in the three forms 10.xxx, 172.16.xx to 172.31.xx, 192.168.xx, and two In the first, the DHCP service that opens ADSL MODEM, dynamically obtain IP, or specifies an IP address of the ADSL MODEM's LAN address in the same network segment, and then point the client's gateway address to the ADSL MODEM's local area network address. .
ADSL MDOEM is a built-in NAT function to achieve a multi-machine shared Internet, and the settings for NAT rules are generally comparable to the comparison NAPT rules. We want to improve the speed of the BT, and set the NAT rules to make the external network can be directly connected to the intranet machine.
For example, after entering the setup page of the ADSL MODEM, select the Service page, then select "Nat Rule Entry" in the NAT Options drop-down box, press the "Add" button in the NAT Rules Settings page, then The "NAT Rule-Add" window is popped, as shown in Figure 13 below.
In this page, "Rule Flavor" item selects "BIMAP", "Rule ID" column to fill in 1, "IP Name" column "all", in the "local address" column, fill in you to carry out BT Download the IP of the machine, "submit" can complete the addition of the rule. Note that if you have a NAT rule that has a rule number in your ADSL MODEM, you must first delete it, then add the same rule, just make it the rule ID is no longer 1. In this way, we add a BIMAP new NAT rule to the IP address of 192.168.1.3 in the ADSL MODEM, making it transparently mapped to the Internet. As shown in Figure 14 below.
After saving, the IP address is 192.168.1.3 Machine BT download speed can basically reach the limit download speed of Modem. Other machines can also refer to the settings, which is no longer detailed here.
Tip: NAT-NETWORK Address Translator, port mapping (also called network address translation), implements mutual conversion between intranet IP addresses and public network IP addresses, which is to forward the request for the specified port to the specified On the IP, let other machines respond to these requests, and the intranet is sent to the external network to randomly assign ports like other gateway services, but the port specified above. BIMAP Rule BIMAP implements two direction conversions. BIMAP rules can be used to provide external network access to LAN devices, using this way, a PC (IP) in the bureau is fully transparent to the public IP, so many complex applications such as MSN voice, online games can be in this PC is running normally.
3, through SOHO ROUTER Internet access
In a lot of small businesses or schools, you are using SOHO ROUTER to provide multi-user Internet service. A ADSL line is connected to Modem, and Modem is connected to SOHO ROUTER's WAN, and SOHO Router is connected to a switch on a switch or PC directly connected to several LAN ports provided by SOHO ROUTER (generally below 8 or less ). We describe how to improve BT download speed as an example for TP_LINK TL-R400 as an example.
Enter the TL-R400 setting page, select "Virtual Server" under "Redirect Rule" in the left main menu, fill in 8881-8999 in "Server Port", fill in "Server IP Address" 192.168.1.10 , Then check "Enable". As shown in Figure 15 below.
Select "Special Application" under the "Redirect Rule" in the left main menu, because there is no BT software we want in the option in the "Common Application" column, so you have to add one yourself. Fill in 8881 in "Trigger Port", fill in 8881-8999 in "Introduction Port", and then check "Enable". As shown in Figure 16 below.
After saving, the IP address can be allowed to allow external machines to access the external machine.
Fourth, solve the method of ISP BT port
More and more users are more and more, some ISP take technical means to block the port used by the BT download software to reach the purpose of preventing users from using BT download, and sometimes because of Xiamen a user BT port and make it boakered. If the ISP has enabled the BT Download Port 8881-8999, we can break through the block by adding parameters by using the command that is turned on when the "Torrent" file is opened in the file type. Specific operation is (as described in Windows 2000):
Select "File Type" in the Folder Items page, find this extension of Torrent, click "Advanced", select "Open" in the open window, then "Edit", in the editing window below It is the command line parameter that starts BT. After adding a space, add a space to add the following control port binding parameters: -Minport minimum port number - MaxPort the highest port number. For example, in my machine is "C: / Program Files / BitTorrent / BtDownloadGui.exe" --Responsefile "% 1", change it to "C: / Program Files / Bittorrent / BtDownloadGui.exe" - Responsefile "% 1" -Minport 8021 -Maxport 8029. The port number is invited to set it yourself, and it is ok to the original 8881-8999. But if our BT download software is the BitTorrent5.x.x test version, you can change the settings directly in the program. Specifically: Click "Properties Settings", you can freely change the port used by the download software in the Properties Settings window. As shown in Figure 17 below.
If your computer is far from the speed of the BT download, you can see the above settings for your own access, or open the BT download software in the _blank "> firewall, It is not that the internal network user makes a map with a computer that comes to BT, so that users on the Internet can contact you directly. After the above settings, your machine is also "running like flying" when the BT is downloaded. I hope everyone can enjoy the fun of high-speed BT downloads.
