Chapter 43 Troubleshooting The threat intelligence machine learning (TIML) feature is not working. 1 Make sure you purchase the gold security pack. • Make sure you've registered the Zyxel Device and activated the anti-malware service on portal.myZyxel.com. • Go to the screen, and select the Enable check box in the Configuration > Security Service > AntiMalware to activate the TIML feature. 2 Make sure the gold security pack is not expired. If it is, renew the license. The Zyxel Device won't scan the TIML signatures that were downloaded when the gold security pack expired. The Zyxel Device's performance seems slower after configuring IDP. Depending on your network topology and traffic load, binding every packet direction to an IDP profile may affect the Zyxel Device's performance. You may want to focus IDP scanning on certain traffic directions such as incoming traffic. IDP is dropping traffic that matches a rule that says no action should be taken. The Zyxel Device checks all signatures and continues searching even after a match is found. If two or more rules have conflicting actions for the same packet, then the Zyxel Device applies the more restrictive action (reject-both, reject-receiver or reject-sender, drop, none in this order). If a packet matches a rule for reject-receiver and it also matches a rule for reject-sender, then the Zyxel Device will reject-both. I uploaded a custom signature file and now all of my earlier custom signatures are gone. The name of the complete custom signature file on the Zyxel Device is 'custom.rules'. If you import a file named 'custom.rules', then all custom signatures on the Zyxel Device are overwritten with the new file. If this is not your intention, make sure that the files you import are not named 'custom.rules'. I cannot configure some items in IDP that I can configure in Snort. Not all Snort functionality is supported in the Zyxel Device. ZyWALL ATP Series User's Guide 884
