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 11.1.2, the SMT uses Set 1.
When you select SUA Only, the SMT uses the pre-configured Set 255 (read

server rule must be set up inside the NAT address mapping set. To configure
