Set Up Incoming Network Address Translation (NAT)
Incoming Network Address Translations (NAT) is used to redirect
requests to servers in the local address space based on the port of the
request. If, for example, the client at local address 10.0.1.2 is serving
web pages, and a request comes to the access point on that port for a web
session, then the request will be forwarded to the web server on 10.0.1.2.
The server will respond with the web page to the address of the original
request.
Note: This screen is only available when the Enable Incoming NAT
checkbox has been selected on the General Setup screen.
Note: Incoming NAT only needs to be configured if servers in the local
(private) address space need to connect with clients in the global (public)
address space. You do not need to turn on Incoming NAT if you are
using Outgoing NAT, and vice versa.
To set up incoming NAT :
1. From the Setup tab, select General Setup. The General Setup screen
is displayed.
2. Make sure that the Enable IP Routing checkbox is unchecked.
3. Select the Enable Incoming Network Address Translation checkbox,
and then click OK to close the General Setup screen.
4. Click the Incoming NAT button on the Setup tab. The Incoming
Network Address Translation Setup screen is displayed, and any
public and private IP address/port pairs that you have previously
defined are displayed in the window.
