Logical systems: NAT - Source NAT interface

Previously, all NAT configurations except for the source NAT interface were supported for logical systems. This option allows you to configure interface NAT port overloading in a root or logical system. 

For example, if the port overloading factor for an SRX3400 device is set to 2, it is multiplied by the maximum port capacity of 63,486, making the port overloading threshold 126972(2*63486). The existing port-overloading option is not supported for logical systems and should not be used in conjunction with port-overloading factor, because the statements can overwrite each other. For example, if port-overloading has been set to off to disable interface port overloading, and subsequently port-overloading-factor is configured with any value greater than 1, the port-overloading-factor will override the port-overloading setting. Use the [all] option for the show security nat interface-nat-ports logical-systems command to display all port usage information for the primary and user logical system.

To configure the port-overloading-factor option, use the [nat source interface] statement in the [security nat] hierarchy. The value entered for the port overloading factor (a number from 1 through the maximum port capacity) is multiplied by the maximum port capacity to set the port overloading threshold.
