Appendix G. RFC1483 Quick Start (IP Routing with NAT)
To illustrate the use of NAT, consider the example from Appendix E. To set up a single public address that will be
used to access the public network, you will use the
NAT
menu on the
WAN/ATM/RFC1483 IP
menu.

From the NAT menu, set N
ETWORK
A
DDRESS
P
ORT
T
RANSLATION
to
E
NABLED
. (This will enable translation and allow you to enter the NAT
options.)

Set P
UBLIC
IP A
DDRESS
M
ODE
to S
PECIFIED
so you can enter your public
address. During transmission, private addresses are translated into this
public (NAPT) address.
You will also need to set up the T
RANSLATION
T
ABLE
to do translation on
the body of the packets for certain protocols, such as FTP, to work
correctly.

From the T
RANSLATION
T

menu, create a new entry by arrowing
into the table.

For P
UBLIC
A
DDRESS
M
