Menu 11.3 Applying NAT to the Remote Node
The following table describes the options for Network Address Translation.
Table 101 Applying NAT in Menus 4 & 11.3
FIELD DESCRIPTION
NAT Press [SPACE BAR] and then [ENTER] to select Full Feature if you have multiple
public WAN IP addresses for your ZyAIR. 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
ZyAIR.
28.3 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. 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.
