That does help, thanks. Is it common for rules directly from outside (Internet) to a server in your private network (inside (outside-to-inside), or does it normally pass some device in the DMZ first?

it will go directly.<br />
you will place hosts in dmz when you want to be sure not to mess with inside &nbsp;(i.e. a webserver ).<br />

Aside from establishing firewall rules between DMZ servers and the outside world (i.e. the Internet). and DMZ severs and the private network, what other types of firewall rules may exist in your environment? Is there any specific terminology for the various types of firewall rules? I am just trying to get a very basic management summary of the various classes of firewall rules that are common.

firewall rule terminology

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

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

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.
