Chapter 9
Network Address Translation (NAT)
This chapter discusses how to configure NAT on the Business Secure 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 108
. The
Business Secure 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 37 on page 107
).
Figure 36
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
Business Secure Router.
Note:
Choose
SUA Only
if you have just one public WAN IP address
for your Business Secure Router.
Choose
Full Feature
if you have multiple public WAN IP addresses for
your Business Secure Router.
