Getting

Guide
Configuring
NAT
Mode
Gateway
This
section
provides
an
overview
of
a
SonicWall
SuperMassive
appliance
operating
as
a
single
network
gateway
in
NAT
mode,
which
is
the
default
mode
for
a
newly
configured
SuperMassive
appliance.
This
section
is
relevant
to
administrators
following
deployment
Scenario
A
.
Overview
of
NAT
Mode
Network
Address
Translation
(NAT)
allows
private
IP
addresses
on
internal
networks
to
be
mapped
to
at
least
one
public
IP
address
on
the
WAN
interface
of
the
SonicWall
security
appliance.
Outbound
traffic
from
the
internal
network
uses
many
‐
to
‐
one
NAT
address
mappings
for
their
LANs,
WLANs,
and
other
internal
networks.
All
traffic
in
SonicOS
must
go
through
both
an
access
rule
and
a
NAT
policy,
a
fundamental
part
of
the
NAT
Mode
architecture.
The
NAT
policy
is
even
used
for
traffic
that
needs
no
IP
address
translation,
such
as
traffic
traveling
between
two
different
LAN
interfaces,
traffic
on
the
simplest
types
of
VPNs,
or
through
Layer
2
Bridged
Mode
/
Transparent
Mode
configurations.
The
SonicWall
SuperMassive
ships
with
the
internal
DHCP
server
active
on
the
LAN
port.
However,
if
a
DHCP
server
is
already
active
on
your
LAN,
the
SonicWall
appliance
will
disable
its
own
DHCP
server
to
prevent
conflicts.
As
shown
in
the
illustration
on
this
page,
ports
X1
and
X0
are
preconfigured
as
WAN
and
LAN,
respectively.
The
remaining
ports
(X2
‐
X17)
can
be
configured
to
meet
the
needs
of
your
network.
In
the
example
diagram,
certain
interfaces
are
configured
for
specific
zones:
•
X1—WAN
•
X0—LAN
•
X8—Wireless
LAN
•
X16—DMZ
NOTE:
No
additional
configuration
is
necessary
to
deploy
your
appliance
as
a
single
network
gateway
in
Many
‐
to
‐
One
NAT
mode.
