Setting Description Inbound Rules
Service
(also referred to as
Service Name)
The service or application to be covered by this rule. If the service or
application does not display in the list, you need to define it using the
Services screen (see Add Customized Services on page 163).
All rules
Action
(also referred to as
Filter)
The action for outgoing connections covered by this rule:
• BLOCK always
• ALLOW always
Note: Any inbound traffic that is not blocked by rules you create is
allowed by the default rule.
Note: ALLOW rules are useful only if the traffic is already covered
by a BLOCK rule. That is, you wish to allow a subset of traffic that is
currently blocked by another rule. Similarly, BLOCK rules are useful
only if the traffic is already covered by an ALLOW rule. That is, you
wish to block a subset of traffic that is currently allowed by another
rule.
All rules
Select Schedule The time schedule that is used by this rule. By default, there is no
schedule assigned (that is, None is selected from the Schedule
drop-down list), and the rule is in effect permanently. For information
about creating schedules, see Set a Schedule to Block or Allow
Specific Traffic on page 177.

secondary WAN address configured)
. On the single WAN port
models, it can be either the address of the single WAN interface or
another public IP address (when you have a secondary WAN
address configured).
