NAT Static Port Mapping Table
Adding entries to the NAT Static Mapping Table lets configured hosts in a private address realm on the Ethernet side of
the SU access hosts in the public network using Network Address Port Translation (NAPT). Up to 1000 entries can be
configured (500 UDP ports and 500 TCP ports).
Adding Entries
To add an entry:
1. Click the Add Table Entries button.
2. Enter the Local IP Address of the host on the Ethernet side of the SU.
3. Select the Port Type: TCP, UDP, or Both.
4. Enter the Start Port and End Port.
5. Click Add.
Editing Entries
To make changes to an entry, click the Edit/Delete Table Entries button. Enter your changes and click OK. To delete an
entry, click the Status drop-down box and select Delete, then click OK.
Supported Session Protocols
The NAT feature supports the following session protocols for both inbound and outbound access with the required
support, applications, and limitations given in the following table.
Certain Internet applications require an Application Level Gateway (ALG) to provide the required transparency for an
application running on a host in a private network to connect to its counterpart running on a host in the public network. An
ALG may interact with NAT to set up state information, use NAT state information, modify application specific payload and
perform the tasks necessary to get the application running across address realms.
No more than one server of a particular type is supported within the private network behind the SU.
