Figure 112   Menu 11.3 Applying NAT to the Remote Node

The following table describes the options for Network Address Translation.

Use the address mapping sets menus and submenus to create the mapping table used to assign 
global addresses to computers on the LAN. Set 255 is used for SUA. When you select Full 
Feature in menu 4 or 11.3, the SMT will use Set 1. When you select SUA Only, the SMT 
will use the pre-configured Set 255 (read only).

The server set is a list of LAN 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 the chapter on NAT web configurator screens for further information on these menus. To 
configure NAT, enter 15 from the main menu to bring up the following screen.

NAT

Press [SPACE BAR] and then [ENTER] to select Full Feature if you have multiple 

public WAN IP addresses for your Prestige.  The SMT uses the address mapping set 

that you configure and enter in the Address Mapping Set field (menu 15.1 - see 

section ).

Select None to disable NAT.

When you select SUA Only, the SMT uses Address Mapping Set 255 (menu 15.1 - see 

section ). Choose SUA Only if you have just one public WAN IP address for your 

Prestige.
