For generic rules, the ZyXEL Device 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 ZyXEL Device applies the Mask (bit-wise ANDing) 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
21.1.1.1 and press
[ENTER]
to open Generic Filter Rule, as shown below.
