startport:endport (e.g. 110:120) denotes the port area.
Individual ports can be entered either with the port number or with
the corresponding service name: (e.g. 110 for pop3 or pop3 for
110).
Action:
Accept means that the data packets may pass.
Refuse means that the data packets are turned away so that the

are "swallowed" so that the sender is not informed of their
whereabouts.

the rule is applied,
- the event is to be logged - set Log to Yes
- or not - set Log to No (default setting)
