I cannot update the IPS/application patrol/IP reputation signatures.
• Make sure your Zyxel Device has the IPS/application patrol/IP reputation service registered and that
the license is not expired. Purchase a new license if the license is expired.
• Make sure your Zyxel Device is connected to the Internet.
I downloaded updated IPS/application patrol/IP reputation signatures. Why has the Zyxel Device
not re-booted yet?
The Zyxel Device does not have to reboot when you upload new signatures.
My Zyxel Device is not performing the action I set in Security Service > IPS when a stream of data
matches a malicious signature.
Make sure you set the Zyxel Device to Prevention mode. The Zyxel Device can only create log messages
in Detection mode.
The content filter category service is not working.
Make sure your Zyxel Device is connected to the Internet.
I configured security settings but the Zyxel Device is not applying them for certain interfaces.
Many security settings are usually applied to zones. Make sure you assign the interfaces to the
appropriate zones. When you create an interface, there is no security applied on it until you assign it to
a zone.
The Zyxel Device is not applying the custom policy route I configured.
The Zyxel Device checks the policy routes in the order that they are listed. So make sure that your
custom policy route comes before any other routes that the traffic would also match.
The Zyxel Device is not applying the custom security policy I configured.
