Chapter 9
Network Address Translation (NAT)
This chapter discusses how to configure NAT on the BCM50a Integrated Router.
Using NAT
SUA (Single User Account) Versus NAT
SUA (Single User Account) is an implementation of a subset of NAT that
supports two types of mapping, Many-to-One and Server. For a detailed
description of NAT set for SUA, see“Address Mapping Sets” on page 92. The
BCM50a Integrated Router also supports Full Feature NAT to map multiple
global IP addresses to multiple private LAN IP addresses of clients or servers
using mapping types.
Applying NAT
You apply NAT via menus 4 or 11.3 (Figure 31 on page 91). Figure 30 shows you
how to apply NAT for Internet access in menu 4. Enter 4 from the main menu to
go to Menu 4 - Internet Access Setup.
Note: You must create a firewall rule in addition to setting up SUA/
NAT, to allow traffic from the WAN to be forwarded through the
BCM50a Integrated Router.
Note: Choose SUA Only if you have just one public WAN IP address
for your BCM50a Integrated Router.
Choose Full Feature if you have multiple public WAN IP addresses for
your BCM50a Integrated Router.
