Appendix F. 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.

IP Routing with NAT

Step

Action

 

 

 

From the NAT menu, set NETWORK ADDRESS PORT TRANSLATION to

1

ENABLED. (This will enable translation and allow you to enter the NAT

 

options.)

 

 

2

Set PUBLIC IP ADDRESS MODE to SPECIFIED 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 Translation Table to do translation on

 

the body of the packets for certain protocols, such as FTP, to work

 

correctly.

 

 

3

From the TRANSLATION TABLE menu, create a new entry by arrowing

into the table.

 

 

 

4

For PUBLIC ADDRESS MODE, select NAPT ADDRESS to use the

previously specified public address.

 

 

 

5

For PROTOCOL, select TCP.

 

 

6

Make sure that TRANSLATE BODY is set to YES.
