6.3Generic Filter Rule

The purpose of generic rules is to allow you to filter non-IP packets. For generic rules, the Prestige treats a packet as a byte stream as opposed to an IP packet. You specify the portion of the packet to check with the Offset (from 0) and the Length fields, both in bytes. The Prestige 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.

Two hexadecimal digits represent a byte, so if the length is 4, the value in either field will take 8 digits, e.g.,

FFFFFFFF.
