unauthorized access to your computer from other people on the Internet. A firewall can be employed on your system using a software or with an external hardware device such as a router to keep intruders on the Internet from coming through your network (router/modem) and harming your system.

Types of firewall protection
The three general types of firewalls are Packet Filters (static packet filtering), Stateful Inspection (dynamic packet filtering, and Application (proxy firewall). Most of the current firewall options available today are a blend of one or more of these three basic firewalls. To make it simpler, we can categorize firewalls into two broad categories: Network Layer and Application. Packet filtering firewalls filter packets based on the header that come through the network. Based on a defined set of rules, the firewall either allows, drops or rejects the packet. Dynamic packet filtering scans each connection and the entire content of the packet rather than just the header. Application firewalls host proxy servers to monitor traffic through a gateway or router.

Virus andÂ spyware protectionÂ are the other levels of support that when used in conjunction with firewalls will provide the best protection to your network. The second issue is that ftp and firewalls are capable of co-existing on the same or separate networks. The problems arise from the fundamental design of ftp and its twin socket approach to transfer data. Firewalls assume everything as hostile and then start opening holes to trusted ports and destinations.

The firewall thatÂ blocks malwareÂ and spyware can also prevent you from viewing web pages or cause your programs to crash. If this happens, follow the given steps to troubleshoot your firewall and get your system function properly again.

If firewall is the reason, then turn off theÂ firewall, and right click on the program’s icon in the task tray and choose ‘Exit’ or ‘Close’, or select ‘Firewall’ in the Control Panel. If the problem page loads properly, the problem is your firewall. Check your Internet browser settings to see if frequently used web scripts are at fault.
