Apply Inspection: If this option is enabled, then Stateful
Filtering is performed and the rule is also applied in the
other direction on the given interface during an IP session.
Source Port: Port number criterion for the computer(s)
from which the packet originates. This field will be dimmed
(unavailable for entry) unless you have selected TCP or
UDP as the protocol. See the description of Src IP Address
for the selection options.
Dest. Port: Port number criterion for the destination
computer(s) (i.e., the port number of the type of computer
to which the packet is being sent). This field will be dimmed
(unavailable for entry) unless you have selected TCP or
UDP as the protocol. See the description of Src IP Address
for the selection options.
TCP Flag: Specifies whether the rule should apply only to
TCP packets that contain the synchronous (SYN) flag, or to
all TCP packets. This field will be dimmed (unavailable for
entry) unless you selected TCP as the protocol.
ICMP Type: Specifies whether the value in the type field in
ICMP packet headers will be used as a criterion. The value
can be any decimal value from 0-255. You can specify that
the value must equal (eq) or not equal (neq) to the
specified value, or you can select any to enable the rule to
be invoked on all ICMP packets. This field will be dimmed
(unavailable for entry) unless you specify ICMP as the
protocol.
ICMP Code: Specifies whether the value in the code field
in ICMP packet headers will be used as a criterion. The
code value can be any decimal value from 0-255. You can
