It will give access to internal machines. It is used to redirect incoming packets with a destination of a public address/port to a private IP address/port inside a network. Today, let us discuss how Support Engineers set up port forwarding for our customers.ĭNAT stands for Destination Network Address Translation that helps to change the destination port in the TCP/UDP headers.
