CHAPTER 33
Network Address Translation
(NAT)
This chapter discusses how to configure NAT on the LAN-Cell.
33.1 Using NAT
" You must create a firewall rule in addition to setting up SUA/NAT, to allow
traffic from the WAN to be forwarded through the LAN-Cell.
33.1.1 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ProxiOS implementation of a subset of NAT that supports
two types of mapping, Many-to-One and Server. See Section 33.2.1 on page 480 for a
detailed description of the NAT set for SUA. The LAN-Cell also supports Full Feature NAT
to map multiple global IP addresses to multiple private LAN IP addresses of clients or servers
using mapping types.
" Choose SUA Only if you have just one public WAN IP address for your LAN-
Cell.
Choose Full Feature if you have multiple public WAN IP addresses for your
LAN-Cell.
33.1.2 Applying NAT
You apply NAT via menu 4 or 11.1.2 as displayed next. The next figure shows you how to
apply NAT for Internet access in menu 4. Enter 4 from the main menu to go to Menu 4 -
Ethernet WAN Setup.
