For example, when you use FlashGet to download sections of a file simultaneously. • Encrypted traffic. This could be password-protected files or VPN traffic where the Zyxel Device is not the endpoint (pass-through VPN traffic). • Traffic through custom (non-standard) ports. The Zyxel Device scans whatever port number is specified for FTP in the ALG screen. • All compressed files within a compressed file. Note that a single file can still be decompressed and scanned if you select Enable file decompression (ZIP and RAR). • Traffic compressed or encoded using a method the Zyxel Device does not support. Finding Out More • See Section 27.6 on page 584 for anti-malware background information. 27.1.1 What You Can Do in this Chapter • Use the Anti-Malware screen (Section 27.2 on page 577) to turn anti-malware on or off, and check the anti-malware signature status. In addition, you can set up anti-malware black (blocked) and white (allowed) lists of malware patterns. ZyWALL ATP Series User's Guide 576
