DESCRIPTION
This refers to the Inside Local Address (ILA), which is the starting local IP
address. Local IP addresses are N/A for Server port mapping.
This is the end Inside Local Address (ILA). If the rule is for all local IP
addresses, then this field displays 0.0.0.0 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 refers to the Inside Global IP Address (IGA). 0.0.0.0 is for a dynamic
IP address from your ISP with Many-to-One and Server mapping types.
This is the ending Inside Global Address (IGA), which is the starting
global IP address. This field is N/A for One-to-One, Many-to-One and
Server mapping types.
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.
2. Many-to-One mode maps multiple local IP addresses to one global IP
address. This is equivalent to SUA (in other words, PAT, or port address
translation), ZyXEL's Single User Account feature that previous routers
supported only.
3. Many-to-Many Overload mode maps multiple local IP addresses to
shared global IP addresses.
4. Many One-to-One mode maps each local IP address to unique global
IP addresses.
5. Server allows you to specify inside servers of different services behind
the NAT to be accessible to the outside world.
