Chapter 7 Network Address Translation (NAT) Screens
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 (i.e., 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.
This is the starting local IP address (ILA). Local IP addresses are N/A for Server port
mapping.
This is the end local IP address (ILA). If your rule is for all local IP addresses, then
enter 0.0.0.0 as the Local Start IP address and 255.255.255.255 as the Local End
IP address.
This field is N/A for One-to-One and Server mapping types.
This is the starting global IP address (IGA). Enter 0.0.0.0 here if you have a dynamic
IP address from your ISP.
This is the ending global IP address (IGA). This field is N/A for One-to-One, Many-
to-One and Server mapping types.
Only available when Type is set to Server.
Select a number from the drop-down menu to choose a server set from the NAT -
Address Mapping Rules screen.
Click this link to go to the NAT - Edit SUA/NAT Server Set screen to edit a server set
that you have selected in the Server Mapping Set field.
Click Apply to save your changes back to the Prestige.
Click Cancel to return to the previously saved settings.
