• Check the ZyWALL/USG's connection to the Ethernet jack with Internet access. Make sure the
Internet gateway device (such as a DSL modem) is working properly.
• Check the WAN interface's status in the Dashboard. Use the installation setup wizard again and
make sure that you enter the correct settings. Use the same case as provided by your ISP.
I cannot update the anti-virus signatures.
• Make sure your ZyWALL/USG has the anti-virus service registered and that the license is not
expired. Purchase a new license if the license is expired.

I cannot update the IDP/application patrol signatures.
• Make sure your ZyWALL/USG has the IDP/application patrol service registered and that the
license is not expired. Purchase a new license if the license is expired.

I downloaded updated anti-virus or IDP/application patrol signatures. Why has the ZyWALL/
USG not re-booted yet?
The ZyWALL/USG does not have to reboot when you upload new signatures.
The content filter category service is not working.
• Make sure your ZyWALL/USG 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 ZyWALL/USG is connected to the Internet.
I configured security settings but the ZyWALL/USG 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 ZyWALL/USG is not applying the custom policy route I configured.
