The following table describes the fields in this menu.
33.2 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 13 on page 289 for further information on these menus. To
configure NAT, enter 15 from the main menu to bring up the following screen.
" On the LAN-Cell, you can configure port forwarding and trigger port rules for
the Ethernet WAN interface and separate sets of rules for the Cellular WAN
interface.
