	specify multiple servers of different types behind NAT to this
	computer. See section 4.4.3 below 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).	0.0.0.0
End	This is the ending local IP address (ILA). If the rule is for all local	N/A
	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 global IP address (IGA). If you have a dynamic	0.0.0.0

4.3.2 Port Forwarding Setup

A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make visible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.

Use Menu 15 - NAT Setup to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port

21.In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. Entry 12 (port 1026) is non-editable (see Figure 4-10).
