LAN WAN Outbound Services Rules
You can define rules that 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. An outbound rule may block or allow traffic between an internal IP LAN address and
any external WAN IP address according to the schedule created in the Schedule menu.
You can also tailor these rules to your specific needs (see “Administrator Tips” on page 5-2 ).
