Appendix C. RFC1483 Quick Start (IP Routing with NAT)
To illustrate the use of NAT, consider the example from
Appendix B. RFC1483 Quick Start (IP Routing)
on
page 204. To add NAT to the IP routing example, use the
NAT
menus.
For more details on the configuration parameters discussed in this section, refer to the following pages:
Router Network Interface Configuration menus beginning on
page 148
IP Routing with NAT
Step
Action
1
The
NAT
menu is found under
R
OUTER
>C
ONFIGURATION
> I
NTERFACES
>
S
ETUP
> NAT
. The
NAT
menu can easily be accessed by pressing
<CTRL+N>
.
The network interface will not appear if a virtual circuit is not defined using
the
L2 P
ROTOCOL
menus.
2
From the
NAT
menu, set
P
ORT
T
RANSLATION
to
E
NABLED
. (This will enable
translation and populate the corresponding NAT menu options.)
3
Set
P
UBLIC
IP A
DDRESS
M
ODE
to either
I
NTERFACE
or
S
PECIFIED
.
•
I
NTERFACE
(default) configures NAT to use the IP address already
assigned to the interface. (In other words, the interface address and the
NAPT address are the same.)
•
S
PECIFIED
allows you to define a different IP address for the NAPT
address (public address for private addresses to be translated into).
For basic NAT, this is all of the configuration that needs to be done. For
specific port translations or 1:1 mapping, you can enter
T
RANSLATION
T
ABLE
.
4
From the
T
RANSLATION
T
ABLE
menu, create a new entry by using the right
arrow to enter the table. Additional entries can be created by highlighting the
first entry index number and pressing the
<I>
key. Entries can be deleted by
highlighting the selected entry index number and pressing the
<D>
key.
5
Create specific NAT translations based on your application.
P
UBLIC
IP A
DDRESS
M
ODE
Use the configured interface IP address as the NAPT
address or use
S
PECIFIED
to set a different public
address to be used for the translation.
P
ROTOCOL
M
ODE
Protocol for this translation. (TCP, UCP, ICMP, TCP or
UDP, TCP UDP or ICMP, All, Specified, and NONE.)
P
RIVATE
A
DDRESS
M
ODE
S
PECIFIED
or
A
NY
I
NTERNAL
. Choosing
S
PECIFIED
brings up the
P
RIVATE
A
DDRESS
option.
T
RANSLATE
B
ODY
Y
ES
or
N
O
. If set to
Y
ES
, this will translate the body of
the data packet and replace the private address with
the NAPT address. Default is
N
O
, which is used for
most applications.
