Chapter 7 Network Address Translation (NAT) Screens

P-791R v2 User’s Guide

96

The following table summarizes these types.

7.2 SUA (Single User Account) Versus NAT

SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two
types of mapping,

Many-to-One

and

Server

. The ZyXEL Device also supports

Full

Feature

NAT to map multiple global IP addresses to multiple private LAN IP addresses of

clients or servers using mapping types as outlined in

Table 24 on page 96

• Choose

SUA Only

if you have just one public WAN IP address for your ZyXEL Device.

• Choose

Full Feature

if you have multiple public WAN IP addresses for your ZyXEL

Device.

7.2.1 SIP ALG

Some applications, such as SIP, cannot operate through NAT (are NAT un-friendly) because
they embed IP addresses and port numbers in their packets’ data payload.
Some NAT routers may include a SIP Application Layer Gateway (ALG). An Application
Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323 or FTP) at the
application layer.
A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses
embedded in the data stream.
When the ZyXEL Device registers with the SIP register server, the SIP ALG translates the
ZyXEL Device’s private IP address inside the SIP data stream to a public IP address. You do
not need to use STUN or an outbound proxy if your ZyXEL Device is behind a SIP ALG.
