Note
This
feature

applies
to
ACE

modules

only
and
was

deprecated

beginning
with
ACE

software

Version
A5(1.0).
You
can

create

more

than

8,000

static

NAT

configurations

(one

static

NAT

configuration

with

a

netmask
is
counted

as

one

configuration).

In

addition,

follow

these

restrictions

and

guidelines

when

using

this
feature:

•
This
feature
is

supported

i

n
routed
mode

only.

•
Only
one

mapped

interface

is

allowed

per
virtual
context.

However,
each
static

NAT

configuration
must
have

a

different

mapped

IP

ad

dress.

•
At
any

point,

you

can

configure

no

more

than

one

next-hop

on

the

mapped

interface.

•
Bidirectional
NAT,

or

in

other

words,

source-address

as

well

as

destination-address

translation,

for
the
same

flow

is

not

supported.

•
You
must


have
fewer
than

1,000

real
IP
addresses

on

t

he
same
subnet

as

the

real

i

nterface.
In
addition,
you

must

have

fewer

than

1,000

mapped

IP

address

on

the

same

subnet

as

the

mapped
interface.

•
If
you

use

this
feature,
we

recommended

that

you

do
not
use

MP-based
NAT
for

the

same

virtual
context.
Procedure
Step
1
Choose

Overwrite

configuration

table

appears.
Step
2
In
the

Static

NAT

Overwrite

configuration

table,

click
Add
to

add

a

new

static
NAT.
Step
3
In
the
Mapped

IP

Address

field,

enter

the

IP

address
to
which

the

real

IP

address
is
translated.
In
a

context,

the

mapped

IP

address

must

be

different

in

each

static

NAT

configuration.
Step
4
In
the

Real

VLAN

Number

field,

choose

the

VLAN

number
of
the
interface

connected

to

the

real

IP
address
network.
The
list

of

available

real

VLANs

includes

routed

mode

VLANs

only

(for

more

information,

see

Interface
Type ).
Step
5
In
the

Mapped

VLAN

Number
field,
choose

the

VLAN

number
of
the

interface

connected

to

the

mapped
IP
address

network.
The
l

ist

of


available

mapped

VLANs

includes

routed

mode

VLANs

onl

y

(f

or

more

information,

see
Interface
Type ).

In

a

context,

the

mapped

interface

must

be

the

same

in

each

static

NAT

configuration.
Step
6
In
the

Real

IP

Address

field,

enter

the
real
server

IP

address

to

be

translated.
In
a

context,

you

must

configure

a

different

address

for

configurations

that

have

the

same

real

server
interface.
Step
7
In
the

Real

IP

Netmask

field,

choose

the

subnet
mask
for
the

real

server

address.
Step
