Configuring NAT information
3. Refer to the following information as displayed within the Static Translation tab.
390
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
controller 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 controller
managed network.
Protocol
Displays the tcp or udp option selected for use with the static translation.
Actual Address
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.
