DESCRIPTION
This refers to the Inside Local Address (ILA), which is the starting 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. 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 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 end Inside Global Address (IGA).
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 (i.e., PAT, port address translation), ZyXEL's Single User
Account feature that previous ZyXEL 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.
