ZyXEL Communications P-334WT Support Notes page 68

3. Address Mapping Sets and NAT Server Sets
Use the Address Mapping Sets menus and submenus to create the mapping table used to assign global
addresses to LAN clients. Each remote node must specify which NAT Address Mapping Set to use. The
P-334WT has one remote node and so allows you to configure only 1 NAT Address Mapping Set. 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 Set1. When you select SUA
Only, the SMT will use Set 255. For the P100IH, there are 8 remote nodes and so allows you to
configure 8 NAT Address Mapping Sets.
The NAT Server Set is a list of LAN side servers mapped to external ports. To use this set (one set for
the P-334WT), a server rule must be set up inside the NAT Address Mapping set. Please see
Server Sets for further information on these menus.
Enter 1 to bring up Menu 15.1-Address Mapping Sets
Let's first look at Option 255. Option 255 is equivalent to SUA in previous ZyXEL routers. The fields in
this menu cannot be changed. Entering 255 brings up this screen.
