Chapter 6 Network Address Translation (NAT) Screens
DESCRIPTION
This is the starting Inside Local IP Address (ILA). Local IP addresses are N/A for
Server port mapping.
This is the end Inside Local IP Address (ILA). 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.
This is the starting Inside Global IP Address (IGA). 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.
This is the ending Inside Global IP Address (IGA). This field is N/A for One-to-one,
Many-to-One and Server mapping types.
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 (i.e., 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.
