Thank you for that clear and easy to understand explanation. So I am clear: <br />
<br />
1) The Front End Firewall protects the rest of the network from internet traffic, based on rules, but specifically traffic is sent to the DMZ from the Front-End Firewall? <br />
<br />
2) The Bad-End Firewall accepts traffic from the DMZ (in this scenario) <br />
<br />
So it would go Internet &gt;&gt;&nbsp;Front-End&gt;&gt; (DMZ) &gt;&gt;&nbsp;Back-End &gt;&gt;&nbsp;Services such as exchange? <br />

Hey All <br />
<br />
Can someone explain what a Front-End and Back-End scenario is in regards to a firewall? And how it works with &nbsp;DMZ? There is all kinds of info out there but it mostly just jumps right into configuring and installation and doesn't really explain the terms. <br />
<br />
<br />
Thanks, <br />

Firewall: Front-End Back-End Scenario

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.

Software Firewalls

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
