Configuring Security Settings
6.2 Firewall
For example, when accessing a website on the Internet, a request is sent out to
the Internet for this site. When the request reaches the FiOS Router, the firewall
identifies the request type and origin (HTTP and a specific computer in the local
network, in this case). Unless the FiOS Router is configured to block requests of
this type from this computer, the firewall allows this request to pass out onto
the Internet. When the website is returned from the web server, the firewall will
associate it with this session and allow it to pass, regardless of whether HTTP
access from the Internet to the local network is blocked or permitted.
Note that it is the origin of the request, not subsequent responses to this
request, which determines whether a session can be established or not.
6.2a General Screen
The "General" screen is used to configure the FiOS Router's basic firewall settings.
