Configuring Network Address Translation (NAT)
Configuring NAT
See Table 8-6 for guidelines on specifying this address.
Table 8-8. Determining the IP Address for the Global Address Field
In the example in which you are configuring destination NAT to allow
public access to your company’s FTP server, you would enter the FTP
server’s private address.
b. In the Global Port field, enter the port to which the Wireless Edge
Services xl Module should forward the traffic.
This optional setting for destination NAT provides port translation.
For example, traffic arrives for your internal Web server on its public
IP address and the standard HTML port 80 (which you specify in the
Local Port field of the Before Translation section). The module trans-
lates the traffic to the Web server’s private address and a private port,
selected by your company. Enter the private address in the Global
Address field and the private port in the Global Port field.
7. Click the OK button.
The static NAT definition is now listed on the Security > NAT > Static Translation
screen. Remember: the translation does not take effect unless you define an
interface as the type on which you configured static destination NAT. (See
“Defining Interfaces as Outside or Inside” on page 8-22.)
Interface Type Address Type IP Address for the Global Address Field
Inside (Private) Destination IP address of an outside device on the outside
network
Outside (Public) Destination IP address on an inside device on the inside
network
