ZyWALL 5/35/70 Series User’s Guide

Chapter 42 Network Address Translation (NAT) 613

The following table describes the fields in this menu.

42.2 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 21 on page 395 for further information on these menus. To

configure NAT, enter 15 from the main menu to bring up the following screen.

Note: On a ZyWALL with two WAN ports, you can configure port forwarding and

trigger port rules for the first WAN port and separate sets of rules for the

second WAN port.

Figure 356 Menu 15: NAT Setup

Note: Configure DMZ, WLAN and LAN IP addresses in NAT menus 15.1 and 15.2.

DMZ, WLAN and LAN IP addresses must be on separate subnets.
