  • Thanks,

    My problem is that my script is creating 3 seperate rules, one per port. I would love to have all the ports into one rule. Under is my current script:

    #==============================================================
    # 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
    $port2 = New-Object -ComObject HNetCfg.FWOpenPort
    $port3 = New-Object -ComObject HNetCfg.FWOpenPort

    $port1.Port = 109
    $port2.Port = 110
    $port3.Port = 111

    $port1.Name = 'MyTestPort' # name of Port
    $port2.Name = 'MyTestPort' # name of Port
    $port3.Name = 'MyTestPort' # name of Port

    $port1.Enabled = $true
    $port2.Enabled = $true
    $port3.Enabled = $true

    $fwMgr = New-Object -ComObject HNetCfg.FwMgr

    $profiledomain=$fwMgr.LocalPolicy.GetProfileByType(0)

    $profiledomain.GloballyOpenPorts.Add($port1)
    $profiledomain.GloballyOpenPorts.Add($port2)
    $profiledomain.GloballyOpenPorts.Add($port3)

    This creates 3 rules with the same name. Is there anyway to get them all into one rule?
