Appendix C. RFC1483 Quick Start (IP Routing with NAT)
To illustrate the use of NAT, consider the example from Appendix B. 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
1.
From the NAT menu, set NETWORK ADDRESS PORT TRANSLATION to
E
NABLED. (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.
3.
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.
4.
From the TRANSLATION TABLE menu, create a new entry by arrowing
into the table.
5.
For PUBLIC ADDRESS MODE, select NAPT ADDRESS to use the
previously specified public address.
6.
For PROTOCOL, select TCP.
7.
Make sure that TRANSLATE BODY is set to YES.
