What recommendations do you have (i.e. cross-connect two racks, etc) since all of my equipment will not fit in one 42U rack ?<br />
<br />
Steps<br />
&nbsp;1. user from outside world<br />
&nbsp;2. firewall #1<br />
&nbsp;3. DMZ --&gt; web application server<br />
&nbsp;4. firewall #2<br />
&nbsp;5. Internal Network --&gt; database server<br />
&nbsp;6. step 4, 3, 2, 1<br />
&nbsp;7. repeat

 2. firewall #1
 3. DMZ --> web application server
 4. firewall #2
 5. Internal Network --> database server

Firewall / DMZ / cross-connect

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

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.
