computer with lan connection and direct connection to internet

(no server or proxy)

What I need:

script that listens to an array of ports on that computer. (and logs the result)

if a port of a second array (ports 20;21;8080;...) is open or used it needs to be blocked /closed immediatly


restrict what a user can do (no http, telnet, ftp,...)

found some examples of firewalls here, but none of them are working for me.

I still can surf the internet

Please help

I used bellow example to start from

Dim $IP = @IPAddress1
Dim $nPORT = 8080

$MainSocket = TCPListen($IP2, $nPORT)
; write mainsocket is
If $MainSocket == -1 Then
    MsgBox( 0, "TCP Error", "Error Listening on TCP" & @CRLF & "@error = " & @error )
;write startwhileloop
While 1
    $Socket = TCPAccept($MainSocket)
  ;write socket:
    If $Socket >= 0 Then
        $recv = ''
        While $recv = ''
            $recv = TCPRecv($Socket, 10000)
       ;Do something here based on the request

the ;write are the places I write debug stuff to the logs

bellow is the log I receive

26/08-2007 18:09:16 tcpstartup:

26/08-2007 18:09:16 $mainsocket is: 264

26/08-2007 18:09:17 startwhileloop

26/08-2007 18:09:17 $socket: -1

26/08-2007 18:09:17 $socket: -1

26/08-2007 18:09:17 $socket: -1


(the socket -1 keeps going on)

First of all, what does the value -1 mean. I know this is a failure. But in practical terms.

That my port don't answer?
