To open the port range in windows firewall

When you click on windows firewall you do not find an option to add a range of ports. You can add only one port at a time. The other way is to add ports range from the command prompt. For this do like this.

In cmd:
 
 FOR /L %I IN (5500,1,5700) DO netsh firewall add portopening TCP %I "Passive FTP"%I
 
 It will add the ports from 5500 to 5700 incremented by 1. The result will be an "OK" for each of the ports. This will be extremely helpful when you try to open the passive FTP ports..
