It is possible to trace any IP interface and inspect individual packet ows between hosts.
This can be achieved by logging onto the box and start a network packet capture by us-
ing the tool tcdump. We recommend to use the -n switch to bypass name resolution (e.g.
tcpdump -n -i lan0). You may also generate a dump in PCAP format using the Web Manager,
download it to your computer and perform further inspections with Wireshark (available at
www.wireshark.org).
