I cannot update the IDP/application patrol signatures.
• Make sure your NXC 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 NXC is connected to the Internet.
I downloaded updated anti-virus or IDP/application patrol signatures. Why has the
NXC not re-booted yet?
The NXC does not have to reboot when you upload new signatures.
I configured security settings but the NXC 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 NXC is not applying the custom policy route I configured.
The NXC 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 NXC is not applying the custom firewall rule I configured.
The NXC checks the firewall rules in the order that they are listed. So make sure
that your custom firewall rule comes before any other rules that the traffic would
also match.
