    Tip

    Firewall Configuration


    A firewall is a type of security mechanism used for preventing security threat in both incoming and outgoing computer traffic. It protects your computer system and/or the private network from intrusions.
    It acts as a barrier, which checks all the incoming and outgoing information to and from your computer or a network based on the firewall settings. Firewalls can be customized according to the level of security required. It filters the messages based on some conditions, such as the IP address, ports, protocols, domain names etc.
    These can be implemented in the hardware, software or sometimes both and scan the entire messages passing through it and veriy whether each block or packet of the message meets the specified security criteria.
    Some operating systems like Microsoft Windows offers built-in firewalls, which are by default turned on to block incoming threats from the Internet. You can also look for any third-party software or hardware firewall to replace the default Windows firewall.
    Types of firewall
    There are various types of firewalls like:
    1. Packet filtering firewall
    2. Application-level gateways
    3. Circuit-level gateways
    4. Hybrid firewall
    The role of packet filtering firewall is to examine the information available in the header of the message packets. The Application-level gateway firewall works on the application layer of the protocol stack. It works in a more intelligent way as compared to the packet filtering firewall.
    Mentioned below are some of the conditions, which help in adding or removing the filters from the firewall:
    1. IP address: Every machine connected to Internet has a unique IP address. You can customize the firewall to block any IP address, if it seems to show an uneven or unauthorized attempt or nature.
    2. Protocols: You can decide which protocols to be included in your firewall’s filters. Some of the commonly used protocols, which can be included in the firewall are: IP, HTTP, TCP, FTP, SMTP etc.
    3. Ports: You can configure the firewall to allow or block any port number.
    Similarly, there are various other conditions which can be used to configure the firewall.

    My dell laptop needs firewall


    Dell now ships all computers ordered through Home and Home Office with software firewalls installed and enabled.

    If you have an older Dell PC that did not originally come with a firewall program and you have not already added a separate firewall program to your PC, you will need to purchase a firewall product.

    If you are using Windows XP operating system, you can use its built-in firewall called Internet Connection Firewall or Windows Firewall.


    If you need any kind of technical assistance to install firewall ,you can contact support cell at http://www.vtechsquad.com/

    How do i open a specific port on my soniwall tz210 firewall router?


    Ports are communication channels for computers and networks.

    Certain applications that run over or connect to the Internet require the use of certain ports.


    Firewalls block the use of many ports because they can be like open doors, which viruses and hackers use to gain control of your computer.


    However, if you have an application that needs to use a port that the firewall has blocked, you can go into firewall and open that port.


    Following these instructions will allow you to open a port in the Windows Firewall and give you guidance for other firewalls.


    Go to the control panel and click on "Windows Firewall."

    If you are using another firewall application, open that application from the Programs menu.


    If you are running Microsoft Firewall, you will have to work with both applications.

    Verify the status of the firewall.


    The first pane that comes up is the general tab and it should indicate whether the firewall is on or not. If the Firewall is not on, chose the "on" option and click "OK."

    Open the Firewall application.


    Go to the "Exceptions" tab and choose "Add Port."

    Give the port opening a name.


    Type in the port number you want to open, then choose either "TCP" or "UDP."

    In most cases you will select TCP.

    UDP is used for connectionless networking that doesn't require an initial connection to send information.


    Or right click on the "Network Internet Access" in the bottom task bar select open network and sharing then select see full map you will see all available connections


    Hope this helps
