ZyWALL 10/50 Internet Security Gateway

9.3NAT 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 as outlined in Table 9-2.When you select SUA Only, the SMT will use the pre-configured Set 255 (read only).

A server set is a list of LAN side servers mapped to external ports. To use this set (one set for the ZyWALL), a server rule must be set up inside the NAT Address Mapping set. Please see section 9.4 for further information on these menus. To configure NAT, enter 15 from the main menu to bring up the following screen.
