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.
