NETGEAR CG814W Reference Manual page 39

A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of
the CG814W Gateway are:
• Inbound: Block all access from outside except responses to requests from the LAN side.
• Outbound: Allow all access from the LAN side to the outside.
You may define additional rules that will specify exceptions to the default rules. By adding custom
rules, you can block or allow access based on the service or application, source or destination IP
addresses, and time of day.
To configure outbound rules on the CG814W Gateway, click the Port Blocking link on the
Advanced section of the main menu.
