3. Refer to the following information as displayed within the 

 tab. 

4. Select an existing NAT configuration and click the 

 button to display screen used to modify the 

settings of this existing NAT configuration. The fields within the Edit screen are similar to those displayed 
when adding a new NAT configuration.

5. Select an existing NAT configuration and click the 

 button to remove it from the list of available 

configurations displayed.

6. Click the 

 button to display screen to create a new NAT configuration and add it to the list of available 

configurations. For more information, see 

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 

 > 

 from the main menu tree.

2. Click on the 

 tab.

Displays the NAT type as either:

• Inside - The set of networks that are 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.

Displays the Direction as either:

• 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. 

Displays the tcp or udp option selected for use with the static translation.

Displays the Local Address used at the local (source) end of the static NAT configuration. 
This address (once translated) will not be exposed to the outside world when the translation 
address is used to interact with the remote destination.

Applies NAT on packets matching the specified port number. The port number matched can 
be either source or destination based on the direction specified. This option is valid only if 
the direction specified is 

.

Modifies the IP address of the matching packet to the specified value. The IP address to be 
modified can be either source or destination based on the direction specified.

Modifies the port number of the matching packet to the specified value. This option is valid 
only if the direction specified is
