Prevent people from accessing native ports through Win7 firewall settings

First of all, to declare this function, personal feeling is not very useful, because most of the time we have to bring the system from the firewall closed. Like small series is certainly closed, because small weave sometimes in the local area network and other people connected to the net, if no matter the system with the firewall then I have no way to play. So the following is about the use of Win7 firewall settings to prevent access to the local port is not practical.

1

Open firewall fire has a lot of, small make up only say one

The Control Panel-> system and security-> Windows Firewall.

2

Click Advanced Settings on the left panel to appear in the Advanced Security Windows Firewall window

Click on the "Inbound rules" on the left and click "New rule" on the right and select "Port"

3

"Next" Select protocols and ports, such as TCP and Port 4000

"Next" SELECT "Block Connection"

4

Next, select as needed

Finally, set the name and click "Finish"

The above is about preventing people from accessing native ports through the Win7 firewall settings . I'm sorry to tell you that you have not personally measured the effect of how, there is a set of people can tell me how the effect oh.
