<p>Hi,</p>

<p>Presently I am doing a project on firewall. Everything is working fine. Here I am filtering all packets going through tcp port. But I need to send a custom page if a page is being blocked. Like "Your Page Is Blocked By Admin". I dont have any idea how to do it. Can I do it using raw socket ? If so please tell me , how to ? Any suggestion will be very helpful.</p>

<p>Thanks.</p>
