Type

Press [SPACE BAR] and then [ENTER] to select from a total of five types. These are 

the mapping types discussed in the chapter on NAT web configurator screens. Server 

allows you to specify multiple servers of different types behind NAT to this computer. 

See section  for an example.

Local IP

Only local IP fields are N/A for server; Global IP fields MUST be set for Server.

Start

This is the starting local IP address (ILA).

End

This is the ending local IP address (ILA). If the rule is for all local IPs, then put the Start 

IP as 0.0.0.0 and the End IP as 255.255.255.255. This field is N/A for One-to-One and 

Server types.

Global IP

Start

This is the starting inside global IP address (IGA). If you have a dynamic IP, enter 

0.0.0.0 as the Global IP Start. Note that Global IP Start can be set to 0.0.0.0 only if 

the types are Many-to-One or Server.
