v1.0, April 2007
For example, if an inbound rule for a schedule is selected as Block Always, then for every
packet that tries to make an outbound connection for that service, a message with the packet’s
source and destination addresses, along with other information will be recorded in the log.
Enabling logging may generate a significant volume of log messages and is recommended for
debugging purposes only.
Additional actions that can be taken on the rules are:
•Edit: Modify the configuration of the selected rule.
•Select All: Selects all the rules in the table.
•Delete: Deletes the selected policy or policies.
•Enable: Enables the selected rule or rules.
•Disable: Disables the selected rule or rules.
•Add: Add a new rule.
To create a new inbound service rule:
1. Click Add under the Inbound Services table. The Add LAN-WAN Inbound Service will
appear.
Note: See “Setting up Port Triggering” on page 4-28 for yet another way to allow
certain types of inbound traffic that would otherwise be blocked by the
firewall.
