Configuring Network Address Translation (NAT)
Configuring NAT
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
zl 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 translates 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
