Setup

Use the Address Mapping Sets menus and submenus to create the mapping table used to assign global
addresses to computers on the LAN. You can see two NAT Address Mapping sets in menu 15.1. You can
only configure Set 1. Set 255 is used for SUA. When you select Full Feature in menu 4 or 11.3, the
SMT will use Set 1, which supports all mapping types as outlined in Table 7-2. When you select SUA
Only, the SMT will use the pre-configured Set 255 (read only).
