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 and the DMZ. 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 and DMZ 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
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.
