Overview

This section with demonstrate the use of Multi-Tap Network Packet Capture with NST. The NST WUI implementation supports simultaneous Packet Capture on up to 4 network interfaces (Quad Tap) per multi-tap capture session. NST uses the Wireshark network protocol analyzer suite for network packet capture. The light-weight network packet capture tool: "dumpcap" is used as the capture engine.

When capturing packets at Gigabit Ethernet rates and one needs total visibility on the link, then a passive tap is required. Net Optics, a global leader in passive monitoring, makes an excellent 10/100/1000BaseT Tap (TP-CU3) for passively allowing access to monitor GigaBit traffic.

The diagram depicted below shows and example Multi-Tap Capture Setup for monitoring GigaBit traffic across a firewall boundary. We will explore the capturing of packets as they transverse the firewall and under go both Network and Port Address Translation.
