Thank you.
A generic proxy, also known as a port forwarder, combines both features of DNAT and masquerading, forwarding all incoming traffic for a specific service to an arbitrary server. The difference to standard DNAT, however, is that a generic proxy also replaces the source IP address of a request with the IP address of the interface for outgoing connections. In addition, the destination (target) port number can be changed as well.
