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.
Server: This type allows you to specify inside servers of different
services behind the NAT to be accessible to the outside world.
