What is reverse firewall?
A fire wall protects a computer incoming data packets. A reverse firewall prevents the computer or more properly a network from sending out mass data packets when it is under control from an outside source.

A firewall is something that protects your computer from viruses--abarrier between your computer and where the viruses come from. A firewall can be hardware, software or a combination. A firewallis generally a network security device or software that activelymonitors incoming and outgoing network t…raffic. It can either allowor block certain traffic based on a defined set of internetsecurity protocols. A firewall acts as a barrier that limits the damages from internaland external cyber attacks. The firewall can be broadly dividedinto host-based and network-based. A host-based firewall isnormally installed on individual servers and monitors incoming andoutgoing network signals. A network-based firewall is establishedin the cloud's infrastructure or it can be a virtual firewallservice. (MORE)

A firewall is usually placed in front of a group of machines and its primary function is to control communication from and to this group of machines. Communication between two machines over the Internet is a stream of packets (datagrams) send in both directions. The firewall examines all packets tha…t is about to be routed through the machine and, based on a set of rules, determines if the packet is allowed to pass through the machine or not. This functionality is often referred as a packet filter. The secondary function of a firewall is to modify the packets passing through the firewall. This is called Network address translation (NAT), as the modifications usually applies to either sender or receiver information contained in the packets. NAT can for example be used to allow machines without a public addressable Internet protocol (IP) number, to access the Internet through a firewall, by using the IP-number of the firewall as the sender identification. This is also called ip masquerading, as it disguises the address of the machines behind the firewall. www.goldstardailynews.com (MORE)
A firewall (in computer/networking terms) is a software program or hardware device that intercepts communications between your computer and the outside network and does some processing on them to help block malicious connections. Software programs install on your computer and are somewhat less eff…ective, but can also offer more features. They only protect the computer they are installed on and must be started and functional in order to work. Hardware firewalls are dedicated devices that sit physically between your computer and the network (internet, etc). They are always on and tend to do a better job because there is no program to start or crash on the PC. However, it's harder for the average user to control what programs can connect out from a hardware firewall. Firewalls aren't absolutely necessary, but quite recommended. There are thousands of sources on the internet for malicious activity, they'll scan the network you're connected to and try to take your PC over for a variety of reasons (sending spam, etc). Very few internet connections are immune to this, though some ISPs sell modems (cable, dsl, etc) with built-in firewalls. As the name suggests it is a virtual wall which protects your computer from outside threats from internet like Hackers, Viruses, Trojans, Spywares etc. to protect your computer against viruses and other stuff like that they are VERY useful A firewall can be either hardware or software. For most home users the easiest way is the software firewall. It can be installed relatively easily and its purpose is to block the ports of the computer and only allow those programs and users to access the system that the administrator allows. It helps to block unwanted users and programs from running and accessing your computer. Yes ,If you do not have one Zone Alarm is recommended. (MORE)

A firewall is a program or piece of network hardware designed to protect computers from unwanted network traffic. They are used to protect computers (or entire networks) from malicious attacks and hack attempts.
In short: it keeps hackers out. Longer: It can monitor ports to prevent hackers from getting in, and also prevents malware/viruses from sending data out. Firewalls are always good to have unless it affects some of your programs.
The term "fire wall" originally meant, and still means, a fireproof wall intended to prevent the spread of fire from one room or area of a building to another. The Internet is a volatile and unsafe environment when viewed from a computer-security perspective, therefore "firewall" is an excellent met…aphor for network security. In computer networking, the term firewall is not merely descriptive of a general idea. It has come to mean some very precise things . (MORE)
Its primary function is to prevent accesses from untrusted (or undesired) external systems to internal systems and services, and to prevent internal users and systems to access external untrusted or undesired systems and services.

Firewall . Each computer that is connected to the Internet (and, more generally, to any computer network ) is likely to become a victim of a computer attack by a hacker. The methodology generally used by hackers consists in scanning the network (by randomly sending out data packets) in sea…rch of a connected computer. Once a computer is found, the hacker searches for a security weakness in order to exploit it and access the data on the machine.. For several reasons, this threat is even greater when the machine is permanently connected to the Internet:. The targeted machine is likely to be connected but not monitored . The targeted machine is generally connected with a greater bandwidth . The targeted machine does not change or rarely changes IP addresses . Therefore it is necessary for both company networks and Internet users with cable or ADSL connections to protect themselves from network intrusions by installing a protection device.. What is a Firewall? . A firewall is a system that protects a computer or a computer network against intrusions coming from a third-party network (generally the Internet). A firewall is a system that filters data packets that are exchanged over the network. Therefore, it is a filtering gateway that comprises at least the following network interfaces:. an interface for the network being protected (internal network) . an interface for the external network . the site to use. http://en.kioskea.net/contents/protect/firewall.php3 (MORE)

You do not create it, you install it, because it is a normal program like any other. Unless of course you want to program/code one of your own. In Windows you can actually use built in firewall. You find it in Control Panel (panel start) and then look for " Firewall ".
Basically firewalls are define in two category software and hardware and both works as well as same but hardware firewall is more secure then software it is necessary because it blocks the untrusted users or networks and pass only trusted users or networks . ( VIKRAM SINGH )
Firewall is a security system which acts as a barrier in protectingyour system from untrusted network accessing your system. Anynetwork that connects to your system must pass through thefirewall, where it get filtered using the rules programmed in thefirewall. The rules programmed in the firewall ca…n be modified ifwanted. There are three types of firewall methods. 1. Packet filtering - This mechanism contains packet filters.Packet filters scans the packets which contains data. 2.Application layer filtering- Application firewall controls theinput, Output from any application or service 3.Proxy filtering- proxy filtering acts as a filters between theclients and the server system.
