6.5.2.1 Adding a New Static NAT Configuration
If existing NAT configurations 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 Static Translation tab.
Type Displays the NAT type as either:
• 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 valid addresses located on the Internet.
Outside addresses pose no risk if exposed over a publicly accessible network.
Direction 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 to reach the LAN over the switch managed network.
Protocol Displays the tcp or udp option selected for use with the static translation.
Local Address
(Actual Address in
RFS4000)
Displays the Local Address used at the (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.
Local Port 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
destination .
Global Address
(NATed Address in
RFS4000) Modifies the IP address of the matching packet to the specified value. The IP
address modified can be either source or destination based on the direction
specified.
Global Port Modifies the port number of the matching packet to the specified value. This
option is valid only if the direction specified is
destination.
