Agregar exepciones al firewall desde C#

Primero agregamos la referencia a la dll:

Microsoft.TeamFoundation.Common

Luego pegamos el código:

public static INetFwMgr WinFirewallManager()

{

Type type = Type.GetTypeFromCLSID(

new Guid("{304CE942-6E39-40D8-943A-B913C40C9CD4}"));

return Activator.CreateInstance(type) as INetFwMgr;

}



public static bool AuthorizeProgram(string title, string path,

NET_FW_SCOPE_ scope, NET_FW_IP_VERSION_ ipver)

{

Type type = Type.GetTypeFromProgID("HNetCfg.FwAuthorizedApplication");

INetFwAuthorizedApplication authapp = Activator.CreateInstance(type)

as INetFwAuthorizedApplication;

authapp.Name = title;

authapp.ProcessImageFileName = path;

authapp.Scope = scope;

authapp.IpVersion = ipver;

authapp.Enabled = true;



INetFwMgr mgr = WinFirewallManager();

try

{

mgr.LocalPolicy.CurrentProfile.AuthorizedApplications.Add(authapp);

}

catch (Exception ex)

{

System.Diagnostics.Trace.Write(ex.Message);

return false;

}

return true;

}

Y por ultimo lo llamamos de la siguiente forma:

AuthorizeProgram("TCP", @"C:\TCP.exe", NET_FW_SCOPE_.NET_FW_SCOPE_ALL, NET_FW_IP_VERSION_.NET_FW_IP_VERSION_ANY);
