Destination NAT (one-to-many)
Another application where DNAT might be used is a scenario in which there are multiple instances (each on a different port) of the server inside a private network. To configure NAT for this particular scenario, perform the following steps in configuration mode.
Create DNAT rule 10.
Apply this rule to all incoming packets on the dp0p1p1 interface bound for the 18.104.22.168 address on a well know http port.
Forward traffic to internal host address 10.0.0.64 across ports 2000-2019 and across 20 instances in this case.
Commit the change.
Show the configuration.
