TIdMappedPortUDP is a
TIdUDPServer descendant that implements a proxy for connections to a remote computer system using the UDP protocol. TIdMappedPortUDP listens for connections on a designated host address and port number, and makes a surrogate connection to another server using a specified port number. This is useful for certain types of proxy programs. TIdMappedPortUDP also implements an event notification mechanism for new connection requests.
