2. Enter or select data for each field that applies to your rule.
The following table describes the fields:
Field Description
Rule ID: Each rule must be assigned a sequential ID number. Rules are
processed from lowest to highest on each data packet, until a
match is found. It is recommended that you assign rule IDs in
multiples of 5 or 10 (e.g., 10, 20, 30) so that you leave enough
room between them for inserting a new rule if necessary.
Action: The action that will be taken when a packet matches the rule
criteria. The action can be [Accept] (forward to destination) or
[Deny] (discard the packet).
Direction: This field specifies whether the rule should apply to data packets
that are incoming or outgoing on the selected interface.
[Incoming] refers to packets coming from the LAN.
[Outgoing] refers to packets going to the Internet.
You can use rules that specify the incoming direction to restrict
external computers from accessing your LAN.
