Field Description
Black List Status
Specifies whether or not a violation of this
rule will result in the offending computer's IP
address being added to the Black List, which
blocks the ADSL/Ethernet router from
forwarding packets from that source for a
specified period of time. See Chapter 17,
“Configuring Firewall Settings” for
instructions.
Log Tag
Specifies a description up to 16 characters to
be recorded in the log in the event that a
packet violates this rule. Be sure to set the
Log Option to Enable if you configure a Log
Tag.
Start/End Time
The time range during which this rule is to be
in effect, specified in military units.
Src IP Address
Specifies IP address criteria for the source
computer(s) from which the packet
originates. In the drop-down list, you can
configure the rule to be invoked on packets
containing:
any: any source IP address.
lt: any source IP address that is numerically
less than the specified address.
lteq: any source IP address that is
numerically less than or equal to the specified
address.
gt: any source IP address that is numerically
greater than the specified address.
eq: any source IP address that is numerically
equal to the specified address.
neq: any source IP address that is not equal
to the specified address.
range: any source IP address that is within
the specified range, inclusive.
out of range: any source IP address that is
outside the specified range.
self: the IP address of the ADSL/Ethernet
router interface on which this rule takes
effect.
Dest IP Address
Specifies 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.
