There is no syntax that you can &nbsp;use to block traffic through which a packet might travel.<br />
<br />
Your best might be to use iptables/snort to setup an IDS/IPS that will reject the requests.<br />

There &nbsp;are apache based tools as well to shield the server to some extent.

My website has been under attack for a couple of weeks now. I have a dedicated server. I started by blocking their IP addresses, but they just keep changing them over and over and over. Basically I want to block the router most of the IP's resolve too:<br />
<br />
adsl-XX-XX-XX-X.dsl.lsan03<wbr />.sbcglobal<wbr />.net<br />
<br />
How do I block all ip's coming from dsl.lsan03.sbcglobal.net? What would the proper syntax be in the htaccess, or how could I add this to csf.deny?<br />
<br />
Any help would be greatly appreciated.<br />

Use htaccess to block specific router names rather than IP Blocks

The Apache HTTP Server is a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards. Typically Apache is run on a Unix-like operating system, but it is available for a wide variety of operating systems, including Linux, Novell NetWare, Mac OS-X and Windows. Released under the Apache License, Apache is open-source software.

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.

Linux Security

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
