LABEL DESCRIPTION
WAN Interface Select the WAN port to use the address mapping rules.
# This is the number of an individual entry.
Local Start IP 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.
Local End IP 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.
Global Start IP 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.
Global End IP 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.
Type 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.
