System 10 distributes information data packets 10D from multiple send endpoint ports 11S in send endpoint unit 12S, to multiple receive endpoint ports 11R in receive endpoint unit 12R. The packets pass through standard based send firewall adapter 14S (shown in detail in FIG. 3), traverse at least one firewall 15W through selected port 15P, and pass through standard based receive firewall adapter 14R. The endpoint units in the send and receive stations may be simple PCs operated by individuals at a single work station, or complex computer system(s) operated by large organizations.
