Configuring NAT information
6
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 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 to reach the LAN
over the switch managed network.
6. Enter the ActualAddress used at the local (source) end of the 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.
7. Enter the Local Port (1 - 65535) used to for the translation between the switch and its NAT
destination.
8. Use the Protocol drop-down menu to select either TCP or UDP as the protocol
NOTE
After selecting (and saving) a protocol type of TCP or UDP (using the Web UI), the switch CLI will not
display the selected protocol type or provide an option to configure it. Ensure both the protocol and
port are defined using the Web UI.
9. Enter the NATed Address to assign to a host in the outside network. This should be interpreted
as a secure address.
