How to open a firewall port in Windows using Power Shell
You can refer to the guide here.
The command to open port 80 is:
netsh advfirewall firewall add rule name="Open Port 80" dir=in action=allow protocol=TCP localport=80
You need to specify:
- name for the rule
- direction
- whether to allow the connection
- protocol used
- port number
You can use this command from the Powershell level.
If you absolutely must use Powershell, you can use something like the script below(for the port 80 as well):
#==============================================================
# Creates a rule to open an incomming port in the firewall.
#==============================================================
#$numberAsString = read-host "type an port number"
#$mynumber = [int]$numberAsString
$port1 = New-Object -ComObject HNetCfg.FWOpenPort
$port1.Port = 80
$port1.Name = 'MyTestPort' # name of Port
$port1.Enabled = $true
$fwMgr = New-Object -ComObject HNetCfg.FwMgr
$profiledomain=$fwMgr.LocalPolicy.GetProfileByType(0)
$profiledomain.GloballyOpenPorts.Add($port1)
