Custom Response Page

a.jones · ‎07-16-2020

Hi All,

Hoping someone can help. I need a custom response page for URL Filtering. I know I need to use Javascript but that is not my forte so hoping can provide the inform for me. I need to produce two distinct page responses depending on the IP address the user comes from ie:

If they come from address range 10.0.0.0/8 a URL response page produces "Page Blocked for Security Reasons"

If they come from any other address range a URL response page produces "Page Blocked because we have the power to do so".

I understand it is a text file I need to upload, it's just the page construct I'm struggling with.

Thanks in advance

Adrian

About to upgrade to 8.1.15-h3.

We are going to 9 or 9.1 in late Sept/Early Oct.

hi @a.jones

do you have user-id configured or not? and are the subnets all /24 subnets?

so in case you are not using user-id and you have /24 subnets you can use the following response page:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
	<head>
		<title>Web Page Blocked</title>
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
		<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
		<meta name="viewport" content="initial-scale=1.0">
		<style>
		  #content {
			border:3px solid#aaa;
			background-color:#fff;
			margin:1.5em;
			padding:1.5em;
			font-family:Tahoma,Helvetica,Arial,sans-serif;
			font-size:1em;
		  }
		  h1 {
			font-size:1.3em;
			font-weight:bold;
			color:#196390;
		  }
		  b {
			font-weight:normal;
			color:#196390;
		  }
		</style>
		<script type="text/javascript">
			function onload()
			{
				var ip = "<user/>";
				var octets = ip.split(".");
				var subnet = octets[0] + "." + octets[1] + "." + octets[2];
				var title = document.getElementById("title");
				var infotext = document.getElementById("infotext");
				switch (subnet) {
					case "10.0.0":
						title.innerHTML = "Title 1";
						infotext.innerHTML = "Infotext 1";
						break;
					case "10.0.1":
						title.innerHTML = "Title 2";
						infotext.innerHTML = "Infotext 2";
						break;
					case "10.0.2":
						title.innerHTML = "Title 3";
						infotext.innerHTML = "Infotext 3";
						break;
				}
			}
		</script>
	</head>
	<body bgcolor="#e7e8e9" onload="onload()">
		<div id="content">
			<h1 id="title">Web Page Blocked</h1>
			<p id="infotext">Access to the web page you were trying to visit has been blocked in accordance with company policy. Please contact your system administrator if you believe this is in error.</p>
			<p><b>User/IP:</b> <user/> </p>
			<p><b>URL:</b> <url/> </p>
			<p><b>Category:</b> <category/> </p>
		</div>
	</body>
</html>

The only thing you need to change is the statements in the switch statement according to your subnets and the title and text you want to display to the user.

Hi,

Apologies for no response. I had been in and out with suspected Covid symptoms for a few weeks.

I have tried this and whether I am doing something wrong.

I need the following IP subnets with the following response:

172.18.24.0/23 and 172.18.26.0/23 responde with

“Access to the web page you were trying to visit has been blocked in accordance with NNC filtering policy. Please contact the Complaints and Compliments team at NNC for more information or if you feel that the site you were attempting to view was inappropriately blocked.”

All other ips responded with:

“Access to the web page you were trying to visit has been blocked in accordance with Corp Partnering filtering policy. Please go to the Corp Partnering webpage for more information or if you feel that the site you were attempting to view was inappropriately blocked.”

This is a multi vsys Palo Alto and this particular vsys is the Public Wifi vsys. All Partners wifi traverses this vsys so there is no Userid but 2 partners want 2 specific subnets with a different response hence my issues.

Regards and thanks as always.

Adrian
