Chapter 9 Network Address Translation (NAT)

BCM50e Integrated Router Configuration - Advanced

Configuring a server behind NAT

Note:

If you do not assign a

Default Server

IP address, the Business Secure Router

discards all packets received for ports that are not specified here or in the remote
management setup.

Follow these steps to configure a server behind NAT:

Enter 15 in the main menu to go to

Menu 15 - NAT Setup.

Enter 2 to go to

Menu 15.2 - NAT Server Setup

Global IP
Start

Enter 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

Server

0.0.0.0

End

Enter the ending global IP address (IGA). This field is

N/A

for

One-to-One

Many-to-One

and

Server types

N/A

After you finish configuring a rule in this menu, press [ENTER]

at the message “Press ENTER to Confirm…” to save your

configuration, or press [ESC] to cancel.
