6.5.3 Configuring NAT Interfaces
The NAT Interface is the VLAN used to route switch data traffic between the source and destination address locations
within the switch-managed network. Any of the default VLANs is available as the NAT interface, in addition to any other
VLANs created. In addition to selecting the VLAN, specify the Inside or Outside NAT type.
To view and configure a NAT interface:
1. Select Security > NAT from the main menu tree.
2. Click on the Interfaces tab.
3. Refer to the following information as displayed within the Interface tab:
4. To Edit an existing interface, select it from the list of available interfaces and click the Edit button.
An Edit Interface screen displays allowing the user to modify the VLAN and interface type (inside or outside).
5. If an interface is obsolete or of no use to the NAT translation process, select it and click the Delete button to remove
it from the list of interfaces available
6. If modifying an existing interface is not a valid option, consider configuring a new interface. To define a new NAT
interface:
a. Click the Add button from within the Interfaces tab.
b. Use the Interface drop-down menu to select the VLAN used as the communication medium between the switch
managed network and its destination (within the insecure outside world).
c. Use the Type drop-down menu to specific the Inside or Outside designation as follows:
• Inside - The set of switch-managed 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.
d. 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.
e. Click OK to use the changes to the running configuration and close the dialog.
f. Click Cancel to close the dialog without committing updates to the running configuration.
Interface Displays the VLAN used as the inside or outside NAT type. All defined VLANs are available from
the drop-down menu for use as the interface.
Type Displays the NAT type as either:
• Inside - The set of switch-managed 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.
