Field Description
Dest IP Address IP address rule criteria for the
destination computer(s) (i.e., the IP
address of the computer to which the
packet is being sent).
In addition to the options described for
the Src IP Address field, the following
option is available:
bcast
: Specifies that the rule will be
invoked for any packets sent to the
broadcast address for the receiving
interface. (The broadcast address is
used to send packets to all hosts on the
LAN or subnet connected to the
specified interface.) When you select
this option, you do not need to specify
the address, so the address fields are
dimmed.
Protocol The basic IP protocol criteria that must
be met for rule to be invoked. Using the
options in the drop-down list, you can
specify that packets must contain the
selected protocol ( eq ), that they must
not contain the specified protocol ( neq ),
or that the rule can be invoked
regardless of the protocol ( any ). TCP,
UDP, and ICMP are commonly IP
protocols; others can be identified by
number from 0-255, as defined by
IANA.
Store State 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 criteria for the computer(s)
from which the packet originates.
This field will be dimmed (unavailable
for entry) if you have not specified a
protocol criteria.
See the description of Src IP Address
for the selection options.
Dest Port Port number criteria 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.
