Is there a way to define a group policy to disable the
Internet Connection Firewall while on the corporate LAN?
 
Hello Andy,


Here is a script you can push down that will ENABLE ICF:

The following jscript will allow one to enable ICF:


NCCF_FIREWALLED = 0x0400;

Main()

function Main()
{
var objShare = new ActiveXObject("HNetCfg.HNetShare.1");
if (objShare == null)
WScript.Echo("Failed to Create HNetCfg.HNetShare object");
else
GetFirewall(objShare);
return;
}

function GetFirewall(objShare)
{
var objEveryConnection = objShare.EnumEveryConnection;
if (objEveryConnection == null)
WScript.Echo( "Failed to enumerate EveryConnection");
else {
var objEveryEnum = new Enumerator(objEveryConnection);
if (objEveryEnum == null)
WScript.Echo("Failed to create enumerator");
else {
for (objEveryEnum.moveFirst(); !objEveryEnum.atEnd();
objEveryEnum.moveNext())
{
var objNetConnection = objEveryEnum.item();
if (objNetConnection == null)
WScript.Echo ("failed to get NetConnection");
else {
var objNetConnectionProps = objShare.NetConnectionProps(objNetConnection);
if (objNetConnectionProps == null)
WScript.Echo ("Failed to get property")
else {
var str=""
str += "Name: " +objNetConnectionProps.Name;
WScript.Echo(str);
str = "Guid: " +objNetConnectionProps.Guid;
WScript.Echo(str);
str = "Device: " +objNetConnectionProps.DeviceName;
WScript.Echo(str);
str = "Status: " +objNetConnectionProps.Status;
WScript.Echo(str);
str = "MediaType: " +objNetConnectionProps.MediaType;
WScript.Echo(str);


if (objNetConnectionProps.Characteristics & NCCF_FIREWALLED)
WScript.Echo ("Firewall Enabled")
else {
var objShareConfig = objShare.INetSharingConfigurationForINetConnection
(objNetConnection)
WScript.Echo ("Firewall Disbled")
if(objShareConfig != null) {
WScript.Echo ("Enabling Firewall");
objShareConfig.EnableInternetFireWall();
} else {
WScript.Echo("failed to get ShareConfig");
}
}
WScript.Echo("")
}
}
}
}
}
}

Cool - it works!
How would the command
objShareConfig.EnableInternetFireWall();
be changed to disable the ICF?

Well Ted to be honest with you I have no idea.

I asked around and was given this though:

NCCF_FIREWALLED = 0x0400;

Main()

function Main()
{
var objShare = new ActiveXObject("HNetCfg.HNetShare.1");
if (objShare == null)
WScript.Echo("Failed to Create HNetCfg.HNetShare object");
else
GetFirewall(objShare);
return;
}

function GetFirewall(objShare)
{
var objEveryConnection = objShare.EnumEveryConnection;
if (objEveryConnection == null)
WScript.Echo( "Failed to enumerate EveryConnection");
else {
var objEveryEnum = new Enumerator(objEveryConnection);
if (objEveryEnum == null)
WScript.Echo("Failed to create enumerator");
else {
for (objEveryEnum.moveFirst(); !objEveryEnum.atEnd();
objEveryEnum.moveNext())
{
var objNetConnection = objEveryEnum.item();
if (objNetConnection == null)
WScript.Echo ("failed to get NetConnection");
else {
var objNetConnectionProps =
objShare.NetConnectionProps(objNetConnection);

WScript.Echo(str);

WScript.Echo ("Firewall Enabled")

var objShareConfig =
objShare.INetSharingConfigurationForINetConnection (objNetConnection)
WScript.Echo ("Firewall Disbled")
if(objShareConfig != null) {
WScript.Echo ("Enabling Firewall");
objShareConfig.EnableInternetFireWall();
} else {
WScript.Echo("failed to get ShareConfig");
}
}
WScript.Echo("")
}
}
}
}
}
}


===============End========================


I am not a big scripting guy, let me know if that works.

objShareConfig.DisableInternetFireWall()
works for disabling the ICF

Thanks for your help.

Thanks for the info Ted, that is funny because I was going to say to try
that but I didnt want to come off as as being rude or anything. : )

I did some more research and found that other script instead.
