To achieve address overloading, the available IPv4 address or port range of 1 to 65,536
addresses is partitioned between Junos OS and NAT as shown below:
Junos OS—1 to 49,159 addresses.
NAPT pool—49,160 through 53,255 addresses.
Junos OS—53,255 through 65,535 addresses.
The number of ports reserved for NAPT pool with address overload feature is 4096.
To enable address-overloading, include the
statement at the
[edit services nat pool nat-pool-name]
The statement enables sharing of IPv4 address between Junos OS and
address-overload
the NAT pool. Along with the
interface statement so that the first available IPv4 address or port of the interface is
picked up for the NAT pool.
You can configure the address overload feature the following ways:
Configure an interface along with the
following example.
pool p3 {
address-overload;
interface ge-0/0/1.0;
port {
range low 49160 high 53255;
}
}
In this case, the primary address on the interface is picked for the NAT pool.
Directly configure a /32 address as shown in the following example:
pool p4 {
address-overload;
address 45.0.0.1/32;
port {
range low 49160 high 53255;
}
}
The statement enables sharing of IPv4 interface address with the NAT pool
interface
along with the port range specified in the pool.
