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 pass (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:

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.
