Quest Windows 7 system comes with a firewall (2)

In many cases, small changes may bring higher usability, Microsoft has been actively listening to opinions from users, they are in the Windows 7 firewall Added some important small features. For example, in Vista, when you create firewall rules, you need to list the port number and IP address
separately, but now you only need to specify the range, which saves a lot of this common management task. time.

You can also create connection security rules to specify which ports or protocols are subject to Ipsec requirements in the firewall console, without the need to use the netsh command. This is a handy improvement for those who prefer to use the GUI.

Connection security rules also support dynamic encryption, which means that if the server gets an unencrypted (but verified) message from a client computer, you can request more secure communication by requiring encryption.

With the Advanced Settings Console, you can set up profiles for each type of network, as shown in Figure 3.

Many users (including some IT professionals) may not have known before that the Vista firewall can filter outbound traffic, detect and perform advanced configuration tasks, because these features are not clearly displayed in the firewall program in the control panel, in window 7 Microsoft created a built-in firewall that is more complete than Vista and an effective alternative to third-party managed firewalls.
