-same_ports [yes | no]
If yes, nat will try to retain the source port without modification for outgoing packets. This can only
be done if the port is not already in use by another connection.
The default is yes.
-disable
The Option is used to disable the nat interface.
-status
This will display all the configured options on nat interface.
Examples:
nat -o -interface atm0
Configures the WAN interface atm0 to use network address translation.
nat -o -alias_address 202.54.30.50
Configures alias address as 202.54.30.50 and maps this IP address to an interface and takes that
as NAT interface.
nat .o -unregistered_only yes
Tells the NAT module to translate only those outgoing packets that bear an unregistered IP
address in the source address field of the packet header.
nat .o -same_ports yes
Tells the NAT to try retaining the same source port while translating outbound packets. However, if
this causes conflict with existing entries in the NAT table, then source port will be modified.
