Chapter 8 Network Address Translation (NAT) NAT In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Port Forwarding A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make visible to the outside world even though NAT makes your whole inside network appear as a single computer to the outside world. 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 P-660H-T1v3s 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 29 on page 119. • Choose SUA Only if you have just one public WAN IP address for your P-660HT1v3s. • Choose Full Feature if you have multiple public WAN IP addresses for your P660H-T1v3s. Finding Out More See Section 8.6 on page 116 for advanced technical information on NAT. 106 P-660H-T1v3s User's Guide

Chapter 8 Network Address Translation (NAT)
P-660H-T1v3s User’s Guide
106
NAT
In the simplest form, NAT changes the source IP address in a packet received from
a subscriber (the inside local address) to another (the inside global address)
before forwarding the packet to the WAN side. When the response comes back,
NAT translates the destination address (the inside global address) back to the
inside local address before forwarding it to the original inside host.
Port Forwarding
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for
example, web or FTP, that you can make visible to the outside world even though
NAT makes your whole inside network appear as a single computer to the outside
world.
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 P-660H-T1v3s 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 29
on page 119
.
• Choose
SUA Only
if you have just one public WAN IP address for your P-660H-
T1v3s.
• Choose
Full Feature
if you have multiple public WAN IP addresses for your P-
660H-T1v3s.
Finding Out More
See
Section 8.6 on page 116
for advanced technical information on NAT.
