Chapter 4 Wizard Setup Figure 41 Anti-Spam Wizard: Direction Recommendations • For e-mail servers on the LAN, DMZ, or WLAN the ZyWALL recommends checking traffic that comes from the WAN to the zone(s) where the e-mail server is located. This is to check for spam coming to the ZyWALL's e-mail server from outside e-mail servers. • For e-mail servers on the Internet, the ZyWALL recommends checking traffic that comes from the WAN to the LAN, DMZ, and WLAN zones. This is to check for spam coming to the ZyWALL's local users from the outside e-mail server. • For e-mail servers located at the other end of a VPN tunnel, the ZyWALL recommends checking traffic that comes from the VPN to the LAN, DMZ, and WLAN zones. This is to check for spam coming to the ZyWALL's local users from the e-mail server at the VPN peer. • If you have (your) e-mail server at the WAN zone, the ZyWALL recommends having anti-spam functionality installed on another device between the e-mail server and the Internet. Another option would be to move the e-mail server to the LAN, DMZ, or WLAN. • Click Back to return to the previous screen. • Click Next to continue. 4.11 Anti-Spam Wizard: Direction Configuration Use this screen to select which traffic directions the anti-spam feature checks for spam. 106 ZyWALL 5/35/70 Series User's Guide
