Network configuration
Network address translation (NAT)

NAT example
The following example shows you how to configure static NAT mappings to run a Web server
and an FTP server on the internal network. This scenario might occur if you use the
controller in an enterprise environment.
By creating static NAT mappings, FTP and HTTP (Web) traffic can be routed to the proper
user. Note that the addresses of these stations are still not visible externally. Remote
computers send their requests to 202.125.11.26, and the controller routes them to the proper
client.
Use the following steps to configure the controller to support this example,.
1. Select Controller >> Network > NAT > Add New Static NAT Mapping.
2. On the NAT mappings page, select Add New Static NAT Mapping.
3. Under Requests for, select Standard Services, and then select http (TCP 80).
4. Under Translate to, specify the IP address of the Web server, for example 192.168.1.2.
The Settings box should now look similar to this:
5. Select Add to save your changes and return to the NAT mappings page. The new mapping
is added to the table.
