User-Defined Fields in the Packet
You can filter IP traffic based
upon specified bit patterns contained within the IP header or the header
of the upper-level protocol. User-defined field filters can be used by
themselves or in conjunction with IP address and/or UDP/TCP port
filters. You can specify the location of the bit pattern to filter, by giving
an “offset” position (starting position, offset from the beginning of the
selected header type) and a length (ending position). See figure 14.
