Chapter 43 Troubleshooting The Zyxel Device's performance seems slower after configuring ADP. Depending on your network topology and traffic load, applying an anomaly profile to each and every packet direction may affect the Zyxel Device's performance. Some of the files I download don't go through Sandboxing even though it is enabled. The Sandboxing feature only applies to certain file types. Check the list in File Submission Options to see if the file types you use are included. If they are, make sure you select their corresponding check box. The Zyxel Device detected a malicious file from Sandboxing, but the file still went through the Zyxel Device and is still usable. Make sure you set your Sandboxing settings to destroy malicious files in the Configuration > Security Service > Sandboxing: Action For Malicious File drop-down list box. The Zyxel Device destroyed/dropped a file/email without notifying me. Make sure you enable logs for your security features, such as in the following screens: • Configuration > Security Service > IDP • Configuration > Security Service > Anti-Malware • Configuration > Security Service > Sandboxing • Configuration > Security Service > Email Security The Zyxel Device routes and applies SNAT for traffic from some interfaces but not from others. The Zyxel Device automatically uses SNAT for traffic it routes from internal interfaces to external interfaces. For example LAN to WAN traffic. You must manually configure a policy route to add routing and SNAT settings for an interface with the Interface Type set to General. You can also configure a policy route to override the default routing and SNAT behavior for an interface with the Interface Type set to Internal or External. I cannot get Dynamic DNS to work. • You must have a public WAN IP address to use Dynamic DNS. ZyWALL ATP Series User's Guide 885
