Select the interface to which you want this rule to apply.
If you want the router to check packets inbound to the interface, click Inbound.
The router checks for a match with the rule before routing it; the router accepts or
drops the packet based on whether the rule states permit or deny. If you want the
router to forward the packet to the outbound interface before comparing it to the
entries in the access rule, click Outbound.
If an information box appears that tells that another Access Rule is associated
with the interface and direction you specified, you can either cancel the operation,
or you can continue, by appending the rule entries to the rule that is already
applied to the interface, or by disassociating the rule with the interface and
associating the new rule.
