I cannot update the anti-malware signatures.
• Make sure your Zyxel Device has the anti-malware 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 cannot update the IDP/application patrol signatures.
• Make sure your Zyxel Device has the IDP/application patrol 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 anti-malware or IDP/application patrol signatures. Why has the Zyxel
Device not re-booted yet?
The Zyxel Device does not have to reboot when you upload new signatures.
The content filter category service is not working.
• Make sure your Zyxel Device has the content filter category 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 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.
