Table 31 Address Mapping edit

Label Description

Type 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.

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 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.

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.
