The Internet Reports section includes reports that show details of traffic transferred through the firewall by the external hosts (hosts outside your LAN). In order to identify your external hosts, you need to first configure your intranets by clicking the Intranet Settings link from the Settings tab. When configured, all hosts outside your configured intranets will be considered as external hosts.
On the top right side of the Report screen, there will be three combo boxes. They are:
The Top 5 combo box lets you choose the level of detail in the reports. By default, the top five values are shown. To show more than 15 values, the report uses only tables. There is an option to display the Graph only.
Below each graph click the Hide Table link to hide the table. Click the Show Table link to see the table again.
The Filter by combo box lets you choose the field of filter in the reports. There will be three field values for filtering. They are:
The Export as combo box lets you choose the format of the reports for export. There will be two formats for exporting. They are:
Click on the PDF to export this report to PDF. Click on the CSV to export this report to CSV format (comma separated values).
The Top External Hosts (Sent+Received) graph shows the top external hosts that are sending and receiving traffic through the firewall. Here you can expect only IP's outside your LAN. The table below the graph shows the IP address, along with the number of hits, bytes received, bytes sent, and the total bytes (sent + received) of traffic generated.
The Top External Protocol Groups (Sent+Received) graph shows the top protocol groups used by external host for sending and receiving traffic through the firewall. The table below the graph shows the protocol group, along with the number of hits, % hits, total bytes of traffic generated and what % of traffic each protocol group constitute to the total traffic.
The Top External Sites graph shows the top external sites that were visited. This is destination based report which list the external servers or sites which served more for the internal hosts. Transaction is not started/initiated by the servers listed here. You can expect all external sites which are browsed more by your internal hosts. The table below the graph shows the host name or IP address, along with the number of hits, the total bytes of traffic to the site, and % of total traffic to the particular external site.
The Top Conversations table lists details like host which initiated the conversation, its destination, the protocol used for the conversation along with the number of hits, the total bytes of traffic generated and % of total traffic for the particular conversation.
