6. Click the Add button to display a screen to create a new NAT configuration and add it to the list of available
configurations. For more information, see
Adding a New Dynamic NAT Configuration on page 6-58 .
6.5.1.1 Adding a New Dynamic NAT Configuration
If the existing NAT configurations displayed with the Configuration prove unsuitable for translation, consider creating a
new one.
To define a new NAT configuration:
1. Select Security > NAT from the main menu tree.
2. Click on the Dynamic Translation tab.
3. Click the Add button.
4. Define the NAT Type from the drop-down menu. Options include:
• Inside - The set of networks subject to translation. These are the internal addresses you are trying to prevent from
being exposed to the outside world.
• Outside - All other addresses. Usually these are valid addresses located on the Internet. Outside addresses pose no
risk if exposed over a publicly accessible network.
5. Define the NAT Direction from the drop-down menu. Options include:
• Source - The inside network is transmitting data over the network its intended destination. On the way out, the
source IP address is changed in the header and replaced by the (public) IP address.
• Destination - Packets passing through the NAT on the way back to the switch managed LAN are searched against
to the records kept by the NAT engine. There the destination IP address is changed back to the specific internal
private class IP address in order to reach the LAN over the switch managed network.
6. Use the Access List drop-down menu to select the list of addresses used during NAT translation. These addresses
(once translated) will not be exposed to the outside world when the translation address is used to interact with the
remote destination
7. Use the Interface drop-down menu to select the VLAN used as the communication medium between the source and
destination points within the NAT configuration. Ensure the VLAN selected represents the intended network traffic
within the NAT supported configuration. VLAN1 is available by default.
8. Use the Enable NAT Address option to configure an IP address to be used during NAT.
9. Enter the IP address to be used during NAT in the NAT Address text field.
10.Refer to the Status field for the state of the requests made from applet. This field displays error messages if
something goes wrong in the transaction between the applet and the switch.
11.Click OK to use the changes to the running configuration and close the dialog.
