Configuring the Source Pool for Inline Static Source NAT44

To configure the source pool for inline static source NAT44:

Create a source pool.

content_copy zoom_out_map
user@host# edit services nat source pool nat-pool-name

Define the addresses or subnets to which source addresses are translated.

content_copy zoom_out_map
[edit services nat source pool nat-pool-name]
user@host# set address address-prefix

content_copy zoom_out_map
[edit services nat source pool nat-pool-name]
user@host# set address address-prefix to address address-prefix

Configure a one-to-one static mapping of the original source addresses to the addresses in the source pool by specifying the first address from the matching source-address prefix that is in the source NAT rule.
```
[edit services nat source pool nat-pool-name]
user@host# set host-address-base ip-address
```
To allow the IP addresses of a NAT source pool to overlap with IP addresses in pools used in other service sets, configure allow-overlapping-pools.
```
[edit services nat]
user@host# set allow-overlapping-pools
```

Configuring the NAT Rule for Inline Static Source NAT44

To configure the NAT source rule for inline static source NAT44:

Configure the NAT rule name.

content_copy zoom_out_map
 [edit services nat source]
user@host# set rule-set rule-set-name rule rule-name

Specify the traffic direction to which the NAT rule set applies.

content_copy zoom_out_map
 [edit services nat source rule-set rule-set-name]
user@host# set match-direction (in | out)

Specify the addresses that are translated by the source NAT rule.

To specify one address or prefix value:

content_copy zoom_out_map
 [edit services nat source rule-set rule-set-name rule rule-name]
user@host# set match source-address address

To specify a range of addresses, configure an address book global address with the desired address range, and assign the global address to the NAT rule:

content_copy zoom_out_map
 [edit services address-book global]
user@host# set address address-name range-address lower-limit to upper-limit
 [edit services nat source rule-set rule-set-name rule rule-name]
user@host# set match source-address-name address-name

Specify the NAT pool that contains the addresses for translated traffic.

content_copy zoom_out_map
 [edit services nat source rule-set rule-set-name rule rule-name]
user@host# set then source-nat pool nat-pool-name

Configure the generation of a syslog when traffic matches the NAT rule conditions.
```
 [edit services nat source rule-set rule-set-name rule rule-name then]
user@host# set syslog
```

Configuring the Service Set for Inline Static Source NAT44

To configure the service set for inline static source NAT44:

Define the service set.

content_copy zoom_out_map
 [edit services]
user@host# edit service-set service-set-name

Configure either an interface service set, which requires a single service interface, or a next-hop service set, which requires an inside and outside service interface.

To configure an interface service set:

content_copy zoom_out_map
 [edit services service-set service-set-name]
user@host# set interface-service service-interface si-slot-number/pic-number/0.logical-unit-number

To configure a next-hop service set:

content_copy zoom_out_map
 [edit services service-set service-set-name]
 [edit services service-set service-set-name]
user@host# set next-hop-service inside-service-interface vms-slot-number/pic-number/0.logical-unit-number outside-service-interface si-slot-number/pic-number/0.logical-unit-number

Specify the NAT rule sets to be used with the service set.

content_copy zoom_out_map
 [edit services service-set service-set-name]
user@host# set nat-rule-sets rule-set-name

Configuring Inline Services and an Inline Services Interface

To enable inline services and an inline services interface:

Enable inline services for the FPC and PIC slot, and define the amount of bandwidth to dedicate to inline services.
```
[edit chassis si-fpc slot-number pic number]
user@host# set inline-services bandwidth (1g | 10g | 20g | 30g | 40g | 100g)
```

Configure the inline services logical interface or interfaces.

If you are using an interface service set, configure one logical unit:

content_copy zoom_out_map
[edit interfaces si-slot-number/pic-number/0
user@host# set unit logical-unit-number family family

If you are using a next-hop service set, configure two logical units and define the inside and outside interfaces:

content_copy zoom_out_map
[edit interfaces si-slot-number/pic-number/0
user@host# set unit logical-unit-number family family
user@host# set unit logical-unit-number service-domain inside
user@host# set unit logical-unit-number family family
user@host# set unit logical-unit-number service-domain outside
