Hello greenwarrior,

A good tutorial on firewalls can be found here

You will find the Firewalls recommended by GeeksToGo here. Scroll down to the FREE FIREWALLS heading.

If you're asking about a particular firewall, tell us what it is and someone who is experienced with that firewall will try to help you.

And remember, if the Windows firewall is on you must turn it off before you install a third party firewall.

Hi Godawgs,
Thank you for your reply.

I read that tutorial and another one on firewalls. I understood most of it but I just have one doubt.
Whats the difference between localhost(127.0.0.1) and internal IP?
Please tell me. I will be grateful to you.
And one more doubt generally I need to allow the localhost(127.0.0.1) in a firewall,right?
And one more question can you please tell me what a HOSTS file is?
Thank you.

None, The internal IP address of 127.0.0.1 is the machine you are using, or the localhost.

And one more doubt generally I need to allow the localhost(127.0.0.1) in a firewall,right?

The localhost does not send any out bound traffic to or receive any inbound traffic from the internet, so there is no reason to include the localhost address in the firewall.

And one more question can you please tell me what a HOSTS file is?

A good tutorial that describes the Hosts file and what it can do can be found here

Hi Godawgs,
Does a firewall hide my IP or hide my MAC address from websites? and also does it make me untrackable to websites? I am asking this because I dont want it to do this.
Thank you.

A third party firewall is designed to allow only the outbound traffic to or inbound traffic from the internet that you give it permission to allow. Below is a link to Gibson Research Corp's Shields Up page. Below the test section are links to more information about firewall/ internet security. Number 7 Personal Firewalls and number 11 Frequently Asked Questions are a good place to start. GRC has tons of information about securing your internet connection.
