QQ is the most popular instant messaging software at present, and it has won the favor of many netizens with its powerful functions, friendly interface and numerous users. The first choice to solve the problem of restricting the use of QQ in company LAN is member login.
It's easy to become a QQ member, but you need 10 Q coins a month, or you can pay directly through QQ gas station with your mobile phone to become a member. With QQ membership, everything will be very simple. Just select Menu → Personal Settings → System Settings → Login Settings → Advanced Options → Member VIP, and then select the appropriate IP and port.
Before choosing this login method, QQ will clearly remind you that if you use this function, the speed will be slow or even very slow. This is normal. After all, if the agent logs in and only uses QQ to send and receive messages, the speed is good. This is much better than not being able to log in.
2.MSN Messenger and Yahoo!
For the convenience of all kinds of users, ICQ and Yahoo! They have launched their own online version.
Now MSN has also launched a network service called MSN Web Messenger. This enables us to talk with friends and relatives online in real time only by using a web browser! Its use method is also very simple:
Enter Microsoft's online MSN service address:/,and you will immediately see the blue button "Start MSN Web Messenger". Click to see the login interface similar to MSN Messenger, enter your email address and password, and you can log in.
When you log in, you will find that the interface is very similar to MSN Messenger, but it is based on the web. It is very simple to use.
With this method, no matter where you are, no matter what kind of computer you use, no matter whether MSN Messenger is installed in your computer or not, no matter whether this Internet gateway supports the port of MSN Messenger, as long as you open the Internet Explorer browser, you can browse the web, then you can log on to MSN@Web!
3. How does 3.BT download software penetrate the firewall?
BT download has become one of the important download methods for many broadband users. Like myself, blockbusters and software were dragged back by BT. However, some companies have installed firewalls in the local area network, blocking all the ports for downloading BT software, so you can't download it quickly. At this time, we should try to get through the firewall and have an affair.
Generally speaking, it is easier to block the download port 888 1-8999 of BT. We can break through this block by adding parameters to the command that runs when the "torrent" file is opened in the file type. The specific operation is (taking Windows 2000 as an example):
Select the file type in the folder options page, find the extension TORRENT, click Advanced, select Open in the open window, and then click Edit. In the edit window, the following line is the command line parameter to start BT. Add a space at the end of the line and add the following parameters to control the port binding: -minport minimum port number -maxport maximum port number. For example, on my machine, it used to be "C:\ Program Files \ BitTorrent \ Bt downloadgui.exe"-response file "%1", but now it is changed to "c: \ program files \ BitTorrent \ Bt downloadgui.exe "-response file"%1"-minport8021-maxport8029. Please set the port number at will, not within the original range of 888 1-8999.
But if our BT download software is BitTorrent5. X.X trial version, we can directly change the settings in the program. Specifically, click "Property Settings" to freely change the port for downloading software in the property settings window.
4, the ultimate means to break through the firewall
Of course, the above methods are all alternatives, not the final means to solve the problem of breaking through the firewall. After all, the function of LAN firewall is powerful. If it is easy to break through, what is the need for this function? Therefore, the ultimate solution to the real problem is very troublesome, requiring auxiliary software, and this kind of software is hard to find, and some even have to pay.
The ultimate means: using Http channel to break through firewall restrictions
Using Http channel software can break through the limitation of firewall and obtain other Internet applications with unique Http access rights. So what is a channel? The so-called channel here refers to a communication method that bypasses the firewall port shielding. The packets at both ends of the firewall are encapsulated in the packet types or ports allowed by the firewall, and then communicate with each other through the firewall. When the encapsulated packets arrive at the destination, they are restored and forwarded to the corresponding server.
Related websites and software:
This is a company that specializes in providing Http channel services. Through their online tunnel server, users in the local area network can use ICQ, E-mail, MSN, QQ, Napster and other software blocked by the firewall.
The tunnel server using http-tunnel must use the Http-tunnel client, that is, the client program of Http-tunnel. The free version of the Http-Tunnel client allows 40Kb/ s data forwarding service.

A) Automatic detection: If you don't know the connection of your machine, you can choose this one.
B) There is no proxy, only firewall (with firewall): users who use local area network and direct internet access choose this one.
C) Specify proxy: If you use a proxy server to surf the Internet, you must also enter the address and port of the proxy server, and if necessary, enter the user name and password.
3. After the connection is established, you can click the "Test" button to test. If you see the prompt "Test Successful", your setup has been completed.
4. After the program runs normally, it can be minimized. It will generate a downward icon in the prompt area of the taskbar, and click Restore.
