Figure 30-2 Menu 11.3: Applying NAT to the Remote Node

The following table describes the fields in this menu.
FIELD
Network When you select this option the SMT will use Address Mapping Set 1 (menu
Address 15.1 - see section 30.2.1 for further discussion). You can configure any of the
Translation mapping types described in the NAT chapter of web configurator parts.
Choose Full Feature if you have multiple public WAN IP addresses for your
ZyWALL.
When you select Full Feature you must configure at least one address
mapping set.
NAT is disabled when you select this option.
When you select this option the SMT will use Address Mapping Set 255
(menu 15.1 - see section 30.2.1). Choose SUA Only if you have just one
public WAN IP address for your ZyWALL.

30.2 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 and the DMZ. 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 and DMZ 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.
