Question 6: How to open the port blocked by firewall? BT download has become one of the important download methods for more broadband users, but why do many users with public IP download with BT so slowly? 10K or so, it is better to download by FTP. In fact, an important reason is that the firewall is installed on the user's machine, which blocks the connection from the external network. Other seeds can't actively connect to your machine, and of course the download speed will not be very fast. If a machine with a firewall wants to speed up BT download, it needs to let BT download software penetrate the firewall, which will lead to an affair. Here's how to make BT practice "walking through the wall".

The settings in the following common firewalls are all based on wind broadcast 1.0.0.7. The default listening port used by wind broadcast is 6699, so we need to set the firewall not to intercept the port of 6699. Of course, in the software, we can specify its listening port ourselves.

First, if XP comes with its own firewall.

Right-click the icon (two small TVs) at the bottom right of the desktop, and select "Change windows Firewall Settings" to open the exception option to see if funpaleyr is checked. Note: Please uncheck "No Exceptions" in the general options.

Question 10: What ports should the firewall open to the website server? I don't know the model of your firewall. Speaking of blood, I'll tell you. An 80 port can hack your workstation. SQL injection is also done through port 80 of the WEB. Once he uploads the trojan horse. Stole the administrator's authority. FTP license. You can claim your server. .

So I want to ask you about the hardware firewall. And how the strategy is done.

For example, netscreen used by my company and the strategy made by VIP used by me. . Map port 80. At the same time, the policy is to prohibit the external network from writing to the server. Because the company didn't leave a message. BBS and other interactions. So you can do this. If FTP. I will use VPN client to do it. So that's no problem.

My classmate's Cisco used another strategy. Limited access to data and ports.
