Note: The ZyWALL checks all signatures and continues searching even after a match
is found. If two or more rules have conflicting actions for the same packet, then
the ZyWALL applies the more restrictive action (
reject-both, reject-receiver or
reject-sender, drop, none
in this order). If a packet matches a rule for
reject-
receiver
and it also matches a rule for
reject-sender
, then the ZyWALL will
reject-both
.
