Chapter 12 Network Address Translation (NAT) Screens The following table describes the labels in this screen. Table 24 Address Mapping Rules LABEL DESCRIPTION Local Start IP This is the starting Inside Local IP Address (ILA). Local IP addresses are N/A for Server port mapping. Local End IP 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. Global Start IP 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. Global End IP 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. 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. 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.

: 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

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.
