I probably should leave it since we are planning on applying for another group of IP's.

Thanks for your help!

Yeah that would work, I would make it simpler though, maybe like:

UserIP = Request.ServerVariables("REMOTE_ADDR")
AllowIP = "172.20.1"
FindDot = InStrRev(UserIP,".")
UserIP = Mid(UserIP,1,FindDot - 1)
IPArray = Split(AllowIP,",")
For x = LBound(IPArray) To UBound(IPArray)
     If UserIP = IPArray(x) Then Response.Redirect "meter.php"
Next
Response.Write "&lt;script&gt;
alert(\"Only customers are allowed to use bandwidth test.\");
badpage='http://www.domain.com/wireless.htm';
document.location.href=badpage;
&lt;/script&gt;"

If you know you're only going to allow one group you don't need to use the array, but if you think you might need to add another group you should keep it.

I want to block all IP addresses except for a certain group.

I don't know ASP that well (I am checking out asp101.com) so is there a way to allow a certain group of IP addresses while blocking all the rest? Would this work?

UserIP = Request.ServerVariables("REMOTE_ADDR")
AllowIP = "172.20.1"
FindDot = InStrRev(UserIP,".")
UserIP = Mid(UserIP,1,FindDot - 1)
IPArray = Split(AllowIP,",")
For x = LBound(IPArray) To UBound(IPArray)
If UserIP = IPArray(x) Then
     Response.Write "
&lt;script&gt;
<!-- 
nextpage='meter.php'; 
document.location.href=nextpage
// -->
&lt;/script&gt;"
Else
Response.Write "&lt;script&gt;
alert(\"Only customers are allowed to use bandwidth test.\")
badpage='http://www.domain.com/wireless.htm'
document.location.href=badpage
&lt;/script&gt;"
End If
Next

Here's some ASP I made, maybe it will help:

UserIP = Request.ServerVariables("REMOTE_ADDR")
BlockIP = "172.20.2,172.20.3,172.20.4"
FindDot = InStrRev(UserIP,".")
UserIP = Mid(UserIP,1,FindDot - 1)
IPArray = Split(BlockIP,",")
For x = LBound(IPArray) To UBound(IPArray)
If UserIP = IPArray(x) Then
     'Put code here to handle bad ips
     Response.Write "Your IP is in the block list"
End If
Next

So basically just enter the IPs you want to block in the BlockIP string separated by a ",", I didn't include the fourth segment of the IP since I assumed you wanted to block the whole range (0-255)

I managed to get the result that I wanted with PHP... while I have a post here, how do you set a range for an IP address in PHP?

For example, this is the scripting that I had to use to get my filter to work:

<?php
PHP 

print \"Verifying Access Rights...Please Wait\";

$IPAllow = array(\"xxx.xxx.xxx.1\",\"xxx.xxx.xxx.2\",\"xxx.xxx.xxx.3\", ....... \"xxx.xxx.xxx.255\");

$IPAllowString = implode (\":\", $IPAllow); 
$verify = getenv(\"REMOTE_ADDR\"); 

if (strstr($IPAllowString,$verify)) { 
echo \"    
&lt;script&gt;
<!--
        nextpage='meter.php';
    document.location.href=nextpage
// -->
&lt;/script&gt;\"; 

} else { 
echo \"
&lt;script&gt;
<!--
    alert(\\"Sorry, only customers may use bandwidth test\\");
    badpage='http://www.domain.com/wireless.htm';
    document.location.href=badpage
// -->
&lt;/script&gt;\"; 
} 
?>

That seems like a waste of time to type out 255 addresses... Hopefully I don't have to add another group of IP's, but it would be nice to know how to set a range of 0-255 for the last octet of the ip addresses.
Thanks,

Moving this to Server-Side Scripting as you'll find the right answers there.

I believe there is an option for MS servers. You can also run Apache on an MS server?

I am using a Windows NT server...I also have a Windows 2000 server.

Do I need a Linux/Unix server?

umm.. I have never used .htaccess files.. what do I need for them, and what are they?

mairving — Wed, 06 Mar 2002 02:15:37 +0000

Just do it using an .htaccess file like so:

<?php
<Limit GET>
order deny,allow
allow from all
deny from IP Address
</Limit>
?>

That will work no matter what browser they are using.
