Destination NAT

Haltdos Destination NAT & Settings

Destination NAT changes the destination address in the IP header of a packet. It may also change the destination port in the TCP/UDP headers. These rules help you to set the destination NAT by specifying the rule name, rule message, and rule priority. Additional rule conditions can also be applied such as Type, Incoming & Outgoing Interface, External and Mapped IP Range, Service Protocol, and Port forwarding.

The typical usage of this is to redirect incoming packets with a destination of a public address/port to a private IP address/port inside your network.
