Chapter 44 Network Address Translation (NAT) The following table describes the fields in this menu. Table 240 Applying NAT in Menus 4 & 11.1.2 FIELD DESCRIPTION Network Address Translation When you select this option the SMT will use Address Mapping Set 1 (menu 15.1 - see Section 44.2.1 on page 676 for further discussion). You can configure any of the mapping types described in Chapter 22 on page 435. Choose Full Feature if you have multiple public WAN IP addresses for your ZyWALL. When you select Full Feature you must configure at least one address mapping set. NAT is disabled when you select this option. When you select this option the SMT will use Address Mapping Set 255 (menu 15.1 - see Section 44.2.1 on page 676). Choose SUA Only if you have just one public WAN IP address for your ZyWALL. OPTIONS Full Feature None SUA Only 44.2 NAT Setup Use the address mapping sets menus and submenus to create the mapping table used to assign global addresses to computers on the LAN, DMZ and WLAN. Set 255 is used for SUA. When you select Full Feature in menu 4, menu 11.1.2 or menu 11.2.2, the SMT will use Set 1 for the first WAN port and Set 2 for the second WAN port. When you select SUA Only, the SMT will use the pre-configured Set 255 (read only). The server set is a list of LAN, DMZ and WLAN servers mapped to external ports. To use this set, a server rule must be set up inside the NAT address mapping set. Please see the section on port forwarding in Chapter 22 on page 435 for further information on these menus. To configure NAT, enter 15 from the main menu to bring up the following screen. " On a ZyWALL with two WAN interfaces, you can configure port forwarding and trigger port rules for the first WAN interface and separate sets of rules for the second WAN interface.
