Configure filter settings for this product.
Here, for packet input, output, and forwarding, the policy is set for packet match conditions and how the packet will be handled if a match is made.
A combination of matching conditions and policies is called a rule. If multiple rules are set, they are checked in order of decreasing index. If a rule is applied, the rules at subsequent indexes are not checked. If none of the rules apply, the default policy is applied.
