The proxy establishes the communication channel by (86) IP addresses. The IP addresses must be (87) . These proxy mechanisms prevent applications that must establish return data channels from establishing their data channels, such as, multimedia applications. IP layer-based proxy mechanisms need additional software (88) for each application that uses (89) channels.
