Understanding NAT Interface Source Pools

When traffic requires source IP address translation and references a specific source pool, JUNOS software draws addresses from that pool when translation is performed. The interface source pool is predefined.

You can reference an interface source pool in a policy or rule by setting a NAT action. JUNOS software translates the source IP address to the address of the egress interface for the traffic matching a policy or rule that references the interface source pool. JUNOS software always applies port address translation (PAT) for the interface source pool.
