Filter Rules The filter rule parameters will be
displayed here (see below).
M Refers to More. More in a set behaves
like a logical AND i.e., the set is only
matched if ALL rules in it are matched.
[Y] means an action can not yet be taken
as there are more rules to check, which
are concatenated with the present rule
to form a rule chain. When the rule chain
is complete an action can be taken.
[N] means you can now specify an action
to be taken i.e., forward the packet, drop
the packet or check the next rule. For the
latter, the next rule is independent of the
rule just checked.
