Other filter attributes
There are three other attributes to each filter:
The filter's order (i.e., priority) in the filter set
Whether the filter is currently active
Whether the filter is set to forward packets or to block (discard) packets
Putting the parts together
When you display a filter set, its filters are displayed as rows in a table:
+-#---Source IP Addr---Dest IP Addr-----Proto-Src.Port-D.Port--On?-Fwd-+

The table's columns correspond to each filter's attributes:
#: The filter's priority in the set. Filter number 1, with the highest priority, is first in the table.
Source IP Addr: The packet source IP address to match.
Dest IP Addr: The packet destination IP address to match.
Proto: The protocol to match. This can be entered as a number (see the table below) or as TCP or UDP if those
protocols are used.
