Data Ports

The NetGuardian-16S's 16 data ports provide reach-through terminal server functionality for connecting multiple
simultaneous users to external equipment via Telnet over LAN. Each port can function as a proxy connection to
an external device, a craft port, a channel port, a TCP or UDP reach-through port. The NetGuardian-16S can
support simultaneous proxy connections for up to five users.
