Note: The original destination addresses, along with other addresses in source and destination NAT pools should never be overlapped within one routing instance. |
JUNOS software allows you to create static NAT rules that configure a one-to-one static mapping between original destination address or subnet and translated destination address or subnet. For a NAT device, the original destination address is the virtual host IP address while the mapped-to address is the real host IP address.

The mapping from original destination address or subnet to translated destination address or subnet in static NAT rule's specify a destination NAT rule. The reverse mapping from translated destination address or subnet to original destination address or subnet in static NAT rule's specify a source NAT rule.
When static NAT is configured on the SRX-series device, the static NAT rules takes precedence over the destination NAT rules during mapping. Similarly it takes precedence over source NAT rules during reverse mapping.
