27.3 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. 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 . When you select
SUA Only
, the SMT will use the
pre-configured Set 255 (read only).
The Server Set is a list of LAN side servers mapped to external ports. To use this set (one set for the
Prestige 10), a server rule must be set up inside the NAT Address Mapping set. To configure NAT, enter 15
from the main menu to bring up the following screen.
