Viewing a packet capture output file on a PC
After you save a capture buffer to a file on the VPN Router disk, download the file
to a workstation and analyze the contents offline using one of many available
tools. The VPN Router does not provide utilities to view and analyze packet
capture data; however, the VPN Router software CD provides a utility called
openpcap
that you use to open and decrypt PCAP files on a PC or workstation.
