I want to use something like LimeWire, Frostwire, Ares, etc, but nothing works because of the firewall. I used to be able to connect to LimeWire, until I updated it with their newer version. Now I can’t use any P2P service.
I add the PORT and the number for the specific P2P and it still won’t connect.
How a Personal Firewall Helps to Protect Your Home Computer From Hackers
There are two types of firewall available to the home computer user. A hardware firewall is a device which sits between your computer and the internet. At home for example it could reside on a broadband router which is used to share your internet connection with a number of computers. One of the advantages of a hardware firewall is that it can be used to protect more than one computer at a time. For this reason hardware firewalls are deployed in corporate networks. For home users who own just one computer a personal firewall is more commonly used and more cost effective.
A personal firewall is a software application that monitors and can block the flow of data between the internet and your computer. The firewall is a key part of your computer security set up. It prevents hackers from gaining access to your computer using an internet connection.
Hackers gain access to your computer through open ports that are used by your computer to communicate with the internet. The most basic firewall programs, like Windows XP’s firewall, monitor and can block “inbound” traffic by closing these ports. If theses ports are closed a hacker cannot access your computer directly via the internet.
More advanced firewall programs like products from ZoneLabs or Symantec also monitor and can block “outbound” traffic. This extra level of security is important and is worth investing in. For example, if malicious software like a Trojan Virus or spyware were installed on your computer without your knowledge the firewall would alert the user when it tried to connect to the internet and prevent it communicating with its host.
A firewall usually works at two basic levels. Firstly, packets of data are analysed based upon IP address and content to see whether they comply with a set of rules which a user can input to. The second level the data is analysed is at the application level. The firewall determines whether an application can send and/or receive data and the port which it should be communicating through.
The firewall “learns” through continuous interaction with the user. It seeks user approval from programs when they first come in to contact with the firewall. Most firewalls also allow the user to allow or block applications through a stored list of program which can be accessed through the firewall’s user interface.
There are a number of sites which will help test your firewall’s effectiveness. A number of these sites are run by security software vendors so it is recommended you test using an independently run site to double-check any results. One of the best independent test sites is run by The Gibson Research Corporation. They offer a free test called “Shield Up!” which can be found at their website – http://www.grc.com. The test checks a number of well-know and vulnerable ports on your computer and then provides some useful additional information to help improve your security while online.
It is important to remember that the firewall is only part of your computer security and does not negate the need for a good anti virus solution, a spyware removal tool and a degree of caution / common on sense on the type of websites a user visits. For example, the firewall will not scan for viruses or remove them from your computer.
Richard Rogers is a owner of a number of computer related sites. One of his sites offers Free Computer Help for Windows XP Users and has just launched his new Registry Cleaner Blog.
I have a firewall on my computer to protect my computer, though it’s blocking where I download music from. Does any one know how to fix that?

Article Source: http://www.articlesbase.com/ – What’s All This I Hear About Firewalls?
A firewall is a system that prevents unauthorized access to a private network. Firewalls are extensively used by businesses, corporations and the government to protect against potential hackers. They act as a barrier between a private network and the Internet. Anything that goes into or out of the network must pass through the firewall. The firewall examines each message to make sure it meets the specified security criteria before passing it through. Just like a literal firewall, a computer firewall prevents a fire (in this case a dangerous intrusion into a private network) from spreading.
You can choose between software and hardware firewalls or choose to install both for added security. Hardware firewalls are a physical gateway between your computer and the Internet. A common example of a hardware firewall is a Cable/DSL router. A router is connected to the modem that supplies your Internet connection and your computer is connected to the router either via Ethernet cable or wireless connection. A router can be configured using a web-based interface to filter out any information you want it to before it reaches our computer’s browser.
A software firewall works in the same way, but without the physical unit. You download the software and configure it to filter out information to and from your computer. Companies often use firewalls to prevent their employees from accessing certain websites or from sending inappropriate email communications. Some people, however, use a firewall to only filter in only one direction—from the Internet. This protects them from unauthorized intrusions from unscrupulous players.
There are many ways that devious people can interfere with unprotected networks and computers. For example, hackers can remotely login to your computer and assume some level of control over it. This control can range from stealing files to running programs to sending spam from your email to trafficking in illegal files to spying on you using your microphone and web cam. Some hackers plant malware (malicious software) on your computer without your knowledge that runs in silently in the background and tracks your computer usage. This is a way to obtain your personal information and steal your identity. The only way to protect yourself is to put up the proper barrier between your computer and those who wish you harm.
Comodo Firewall Pro is a Free Firewall Software program from a leading certification authority and security solutions provider. This software provides a suite of security features that are simple enough for beginners to install but can be highly customized by advanced users. Comodo Firewall Pro focuses on preventing malware from installing on your computer. Traditional firewall software has been “detection-based.” These programs waited for malware to be installed on your computer and then alerted you to its presence. In the interim damage could be done. Comodo Firewall Pro takes a more proactive stance against malware and restricts installation of all software unless it is on a pre-approved list of clean applications (there are over 1 million applications on this list) or it is specifically approved by the user. Never allowing the malware to reach your computer, Comodo Firewall Pro prevents damage from occurring.

At their most basic, firewalls work like a filter between your computer/network and the Internet. You can program what you want to get out and what you want to get in. Everything else is not allowed. There are several different methods firewalls use to filter out information, and some are used in combination. These methods work at different layers of a network, which determines how specific the filtering options can be.

When it comes to firewalls, there are several different types available. They are differentiated primarily by the methods they use to filter data. An in-depth understanding of firewalls requires an understanding of the four basic categories they fall into—packet filters, circuit level gateways, application level gateways and stateful inspection firewalls. Firewall products can use one or more of these methods.

When I open Limewire it does not connect, and I’m wondering if it is a Firewall issue.
Thanks for the help.
