Chapter 7 Network Address Translation (NAT) Screens

P-793H User’s Guide

Use this screen to edit an address mapping rule. Click the rule’s edit icon in the Address 
Mapping screen to display the screen shown next. 

Figure 51   NAT > Address Mapping > Edit

The following table describes the fields in this screen. 

Type

1-1: One-to-one mode maps one local IP address to one global IP address. Note 

that port numbers do not change for the One-to-one NAT mapping type. 
M-1: Many-to-One mode maps multiple local IP addresses to one global IP address. 

This is equivalent to SUA (in other words PAT, port address translation), ZyXEL's 

Single User Account feature that previous ZyXEL routers supported only. 
M-M Ov (Overload): Many-to-Many Overload mode maps multiple local IP 

addresses to shared global IP addresses. 
MM No (No Overload): Many-to-Many No Overload mode maps each local IP 

address to unique global IP addresses. 
Server: This type allows you to specify inside servers of different services behind 

the NAT to be accessible to the outside world. 

Modify

Click the edit icon to go to the screen where you can edit the address mapping rule.
Click the delete icon to delete an existing address mapping rule. Note that 

subsequent rules move up by one when you take this action.

Choose the port mapping type from one of the following. 
One-to-One: One-to-One mode maps one local IP address to one global IP 

address. Note that port numbers do not change for One-to-one NAT mapping type.
Many-to-One: Many-to-One mode maps multiple local IP addresses to one global IP 

address. This is equivalent to SUA (in other words PAT, port address translation), 

ZyXEL's Single User Account feature that previous ZyXEL routers supported only. 
Many-to-Many Overload: Many-to-Many Overload mode maps multiple local IP 

addresses to shared global IP addresses. 
Many-to-Many No Overload: Many-to-Many No Overload mode maps each local IP 

address to unique global IP addresses. 
Server: This type allows you to specify inside servers of different services behind the 

NAT to be accessible to the outside world.

Local Start IP

This is the starting local IP address (ILA). Local IP addresses are N/A for Server port 

mapping.
