Address Mapping Settings
Choose the port mapping type from one of the following.
1. One-to-One: One-to-one mode maps one local IP address to
one global IP address. Note that port numbers do not change for
One-to-one NAT mapping type.
2. Many-to-One: 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), Business Secure Router's
Single User Account feature.
3. Many-to-Many Ov (Overload): Many-to-Many Overload mode
maps multiple local IP addresses to shared global IP addresses.
4. Many One-to-One: Many One-to-one mode maps each local IP
address to unique global IP addresses.
5. Server: This type allows you to specify inside servers of
different services behind the NAT to be accessible to the outside
world.
This refers to the Inside Local Address (ILA), that is the starting
local IP address. Local IP addresses are N/A for Server port
mapping.
This is the end local IP address (ILA). If your rule is for all local IP
addresses, then enter 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.
This is the starting global IP address (IGA). Enter 0.0.0.0 here if
you have a dynamic IP address from your ISP.
This is the ending global IP address (IGA). This field is N/A for
One-to-one, Many-to-One and Server mapping types.
