Configuring a Generic Filter Rule
This section shows you how to configure a generic filter rule. With generic rules
you can filter non-IP packets. For IP packets, it is generally easier to use the IP
rules directly.
For generic rules, the Business Secure Router treats a packet as a byte stream as
opposed to an IP or IPX packet. You specify the portion of the packet to check
with the
Offset
(from 0) and the
Length
fields, both in bytes. The Business
Secure Router applies the Mask (using the bit-wise-AND action) to the data
portion before comparing the result against the Value to determine a match. The
Mask
and
Value
are specified in hexadecimal numbers. Note that it takes two
hexadecimal digits to represent a byte, so if the length is 4, the value in either field
will take 8 digits, for example,
FFFFFFFF
.
To configure a generic rule, select
Generic Filter Rule
in the
Filter Type
field
in menu 21.1.4.1 and press
[ENTER]
to open Generic Filter Rule, as shown in
