No route to host with nc but can ping

Question

I am a bit new to flash and actionscript but i am learning. With this code I am trying to get a message that says true when the value is between from and to. When I run this it gives the error in the title. What am I doing wrong?

from = Number(txtFra.text);
value = Number(txtTall.text);
to = Number(txtTil.text);
var from:Number;
var value:Number;
var value:Number;

function insideIntervall(from:int, value:int, to:int):Boolean
{
    var bool:Boolean
    if (from<value<to)
    {
        bool = true;
    }
    else
    {
        bool = false;
    }
    if (bool == true)
    {
        trace("True");
    }
    else
    {
        trace("False");
    }
}

Solution

Your no route to host while the machine is ping-able is the sign of a firewall that denies you access politely (i.e. with an ICMP message rather than just DROP-ping).

See your REJECT lines? They match the description (REJECT with ICMP xxx). The problem is that those seemingly (#) catch-all REJECT lines are in the middle of your rules, therefore the following rules won't be executed at all. (#) Difficult to say if those are actual catch-all lines, the output of iptables -nvL would be preferable.

Put those REJECT rules at the end and everything should work as expected.

Your function definition has ):Boolean at the end, which means there's a contract that says this function will return a true or false value. Likely what you want to do is just return bool at the end of the function.

plus the code outside the function (above it in the code) is somewhat strange: from and value are assigned a value before being declared and the latter is declared twice.
