signature or click the
Edit
icon to edit an existing signature. You can also delete custom signatures here
or save them to your computer.
Note: The Zyxel Device 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 Zyxel
Device 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 Zyxel Device will
reject-both
.
