Description
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 (for
example, PAT, port address translation), the 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: With this type, you can specify inside servers of different
services behind the NAT to be accessible to the outside world.
This is the starting Inside Local IP Address (ILA). Local IP
addresses are N/A for Server port mapping.
This is the end Inside 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 Inside Global IP Address (IGA). Enter 0.0.0.0
here if you have a dynamic IP address from your ISP.
