Hi Friends,
Is anyone help me to aware about different types of the firewall?
The only thing which I know about firewall is that, firewall is used to restrict the particular web-site
Please let me know in detail about the different type of the firewalls.
Thanks in advance.

Restrictions not only for web-sites, for any network access.

Firewall is very good explained on Wikipedia
