| A NAT | Add NAT Alias entry (Administrator) |
| A NAT PR:xxx [par:val] |
This command adds a new entry in the Table of NAT Alias with "PR:xxx" priority and, eventually, it sets the indicated parameters to the specified values.
There can be up to 255 entries in the Table of NAT Alias, therefore the priority value indicated must be in the interval [0 - 254].
If a entry with "PR:xxx" priority already exists in the table and a new entry with the same priority is going to be added, then the old one's priority will be incremented by one (PR:xxx+1).
If the new "PR:xxx" value is higher than the maximum value already existing, then new entry priority will be the maximum one incremented by one.
If the table is full and a new entry is going to be added, then an error message will be displayed "NAT TABLE IS FULL, COMMAND NOT EXECUTED"
Changes made on the Table of NAT Alias are not immediately active. They can be activated by executing the command INIT NAT or by executing the initialization command INIT PO:xxx, where "xxx" is the NAT port number.
The "Not Saved (SAVE CONF)" message is displayed every time the table is modified but not saved with the SAVE CONF command.
The "Not Refreshed (INIT)" message is displayed every time the table is modified but not refreshed with the INIT NAT command or the INIT PO: command.
If the Abilis CPX version, currently in use, does not support NAT services, the following message will be shown "NAT SERVICE NOT PRESENT".
| C NAT | Clear NAT Alias entry (Administrator) |
| C NAT PR:xxx |
This command removes from the Table of NAT Alias the entry, whose priority is "PR:xxx". Priority value must be in the interval [0 - 254]. Entries, whose priority is higher than the deleted one, are decremented by one, so that the table is still contiguous.
If the indicated priority does not match an already existing entry, the following message will be displayed "NAT TABLE ENTRY NOT PRESENT".
If the table is empty, the following message is generated: "NAT TABLE IS EMPTY".
