11-12 Dial-in Setup
Table 11-6 Menu 15.1.1.1 Address Mapping Rule
FIELD DESCRIPTION EXAMPLE
Type Press [SPACE BAR] and then [ENTER] to select from a total of five types.
These are the mapping types discussed in Table 11-2. Server allows you
to specify multiple servers of different types behind NAT to this computer.
See section 11.5.3 for an example.
One-to-One
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 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.
N/A
Global IP
Start This is the starting 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.
0.0.0.0
End
This is the ending global IP address (IGA). This field is N/A for One-to-
One, Many-to-One and Server types.
N/A
Server
Mapping Set
Only available when Type is set to Server. Type a number from 1 to 10 to
choose a server set from menu 15.2.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to confirm or ESC to
cancel” to save your configuration or press [ESC] to cancel and go back to the previous screen.
11.4 NAT Server Sets – Port Forwarding
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.
