How does BT download software penetrate firewall

BT download has become one of the most important downloading methods for broadband users, just like myself, big movies and software are dragged back with BT, and the hard disk is fast. No more. But why do many users with public IP addresses use BT to download at a slower rate? About 10K, it is not comparable to FTP download. In fact, an important reason is that the user's machine has a firewall installed, the firewall blocks the connection from the external network, other seeds can not actively connect to your machine, of course, the download speed will not be fast. In the case of a machine with a firewall installed to speed up the BT download speed, it is necessary to make the BT download software penetrate the barrier of the firewall, and come to a "apricot out wall". The author below will tell you how to make BT practice "through the wall."

BT download software may be different for readers. The following settings in various common firewalls are based on BitTorrent Plus! 5.8.7. The default download port used by BitTorrent Plus! 5.8.7 is 6881-6889. We need to set the firewall to not intercept the port of 6881-6889. Of course, in the software we can specify the port for downloading.

First, XP comes with a firewall

XP comes with ICF, is the abbreviation of "Internet Connection Firewall", which is the Internet connection firewall. ICF is built between our computer and the Internet. It allows the data you request to pass, and blocks the packets you don't request. It is a packet-based firewall. In the use of BT, sometimes due to the blocking of ICF, causing the connection to be less than SEED or packet delay to slow down the download speed, so it is necessary to set the port used by BT in ICF without blocking.

Right click on "My Neighbors", select ""Properties" from the pop-up menu, pop up "Network Connection" window right click on the connection you use for the Internet, select " in the pop-up menu The attribute ", pops up the "Local Connection Properties" window, selects the "Advanced" tab, clicks the "Set" button at the bottom of the window, and the "Advanced Settings" window pops up. This page is some common web services, now we need to add the port used by the BT download software, click the "Add" button below, pop up "Service Settings"Window
In the Service Settings window , "service description" is a description of the web service, you can fill it in (such as "BT download service")," the name of the computer hosting this service on your network or In the IP address " column is to fill in the IP address or machine name of the machine to be BT downloaded (if my machine name is SERVER), " external port number of this server" fill in 6881, " this server The external port number " is also filled in 6881. Of course, don't forget to select the TCP protocol and press , then click the "OK" button.

This adds a "BT download service" network service project in the "Services" column of the "Advanced Settings" page. This service is open to port 6881. In the same way, we will open a new service for the 6882~6889 port. With this setup, our BT download software is now available in the ICF.
