A proxy server is a computer on your network that shares an Internet connection with other client computers on the network. If you have Windows firewall running on your Windows proxy server, the firewall software blocks users from using the proxy server ports. Blocking ports inhibits use of the proxy service, so you must "open" the port in the Windows firewall software. Windows provides a wizard to help you set up the firewall on your proxy server.
Frostwire is a peer-to-peer, file-sharing application based on the Limewire source code. Like other file-sharing and server applications, Frostwire needs incoming ports unblocked on the computer's firewall so it can connect to the network and download and upload files. Windows' built-in firewall automatically blocks incoming network traffic for server applications such as Frostwire, but you can unblock Frostwire's incoming traffic in the Windows firewall control panel window. Frostwire uses UPnP to unblock traffic automatically on new routers, but this step must be done manually for the Windows firewall.
Bearshare 5.2.1 is a file sharing program that uses the Gnutella network to allow users to upload and download files through other users. When you open the Bearshare program to access files, the software will attempt to connect through the Internet. Because of the threat of viruses, Windows Firewall will not allow Bearshare to connect. You can resolve this problem by adding Bearshare to Windows Firewall as an exception.
The Cisco PIX 501 Firewall offers protection to small businesses by securing all communications flowing in and out of the server.

The Windows Firewall is designed to keep spyware and viruses off of your computer, but it can also regulate Internet connections for P2P applications.
Real VNC is a software application that lets network administrators remotely control other computers on the network. When you try to connect to the computer, the Symantec Norton Firewall software blocks the port, so you are unable to make the VNC connection. You must open the VNC port end point before you can connect to the remote computer. You open the VNC port using the main firewall configuration interface.
BitTorrent is a peer-to-peer file-sharing protocol that is commonly used to share large files over the Internet. The protocol allows for a user to download data from a large number of peers instead of from a single server, which increases the speed and reliability of most downloads. A firewall is a program that blocks unauthorized access from hacking threats outside the network. Sometimes, a firewall will prevent a user from using BitTorrent, because it does not recognize the program as non-malicious software. To fix this problem, you'll need to alter the firewall's settings.

A hardware firewall is a physical device that filters information coming into a private network or a private computer through an Internet connection via a server. Hardware firewalls are typically found in routers and are used to protect broadband connection networks. These are generally routers that examine a packet header to determine where it is coming from and where it is going; this information determines whether it is forwarded across the network or denied entry. For maximum security, a hardware and a software firewall are used together. Configuration involves creating a set of rules to allow or deny access to…
Bearshare is a program that allows you to share files with other people. Unfortunately, some firewalls, such as Comodo, may not initially recognize that Bearshare is a legitimate program. This means that if you decide to run Bearshare while Comodo's Firewall software is running, Bearshare will not be able to connect. Therefore, you will need to add Bearshare to Comodo's program list.
FrostWire is the open source version of the peer-to-peer file sharing program LimeWire. The Frost Wire program uses Gnutella and BitTorrent protocols and is written in the Java programming language. It also does not contain advertisements in the program, which is similar to the free version of LimeWire. In order to use FrostWire on your computer, the firewall must be configured to permit FrostWire operations to occur, or you will not be able to exchange files using the program.
