Open Port Range In Windows Firewall

[PMagic]

It is quite difficult situation when you want to open a port range in the Windows Firewall as the firewall GUI not allows you to open a range of ports easily.

You can overcome this situation and open the port range using the following command :

FOR /L %I IN (Minimum_Port,increment,Maximum_Port) DO netsh firewall add portopening PROTOCOL %I "Name Of Rule"%I

Note :

Minimum_Port = The starting port number in the range that you would like to open.

Maximum_Port = The last port number in the range that you would like to open.

Increment = This should be 1

PROTOCOL = Either TCP or UDP

Name Of Rule = Name of the rule

Re: Open Port Range In Windows Firewall

The exact command where you want to open say 100 ports from 500 to 600, would be the following:

FOR /L %I IN (500,1,600) DO netsh firewall add portopening TCP %I "open-tcp-500-600" %I
