etsysFWPolicyRuleDefFilter points to a filter which is used to
evaluate whether the action associated with this row should
be fired or not. The action will only fire if the filter
referenced by this object evaluates to true.
This MIB defines the following tables which may
be pointed to by this column. Implementations may choose to
provide support for other filter tables or scalars as well:
etsysFWIpHeaderFilterTable
etsysFWIpOptionsFilterTable
If this column is set to a VariablePointer value which
references a non-existent row in an otherwise supported
table, the inconsistentName exception should be returned.
If the table or scalar pointed to by the VariablePointer is
not supported at all, then an inconsistentValue exception
should be returned.
