Understanding Static NAT on J-series Services Routers

Static NAT is a direct one-to-one mapping of one IP address to another without port address translation. The mapping is done by a single IP address or by a subnet.

Note: Static NAT is not supported on SRX-series services gateways at this time.

When static NAT is set for an interface in any zone, an entry for the static NAT is generated in the junos-global zone address book in the following format: static_nat_w.x.y.z_n, where w.x.y.z_n is the static NAT. The junos-global zone address book stores all the static NAT addresses, regardless of the zone to which their interface belongs. You can use these static NAT addresses as destination addresses in policies between any two zones to regulate the traffic and to perform destination IP address translation.
