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-Oneand Server mapping types.

Rule

This is the rule’s index number.

 

 

 

 

Type

1-1: One-to-One mode maps one local IP address to one public 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 public

 

 

IP address. This is equivalent to the Single IP feature that previous

 

 

ZyXEL routers supported only.

 

 

M-M Ov (Overload): Many-to-Many Overload mode maps multiple local

 

 

IP addresses to shared public IP addresses.

 

 

MM No (No Overload): Many-to-Many No Overload mode maps each local

 

 

IP address to unique public 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 inside local IP address. Local IP addresses are N/A for

 

 

Server port mapping.

 

 

 

 

Local End IP

This is the ending inside local IP address. If the rule is for all local IP

 

 

addresses, then this field displays 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.

 

 

 

 

Public Start IP

This is the starting inside public IP address. Enter 0.0.0.0 here if you have

 

 

a dynamic IP address from your ISP. You can only do this for Many-to-

 

 

One and Server mapping types.

 

 

 

 

Public End IP

This is the ending inside public IP address. This field is N/A for One-to-

 

 

one, Many-to-One and Server mapping types.
