A customer recently contacted us with a use case where they had a number of VPN sites connecting to their network and they had been advised, following a penetration test, to shut down any unused ports to these sites. The customer wanted to know if LANGuardian could generate a historic report of all application ports that had been used on the VPN link.

Our support team showed the network administrator how to set up a Traffic Distribution report for the IP addresses associated with the VPN. Using this report, he could see at a glance what ports were in use on the VPN link and could then disable any ports that should not have been enabled. The report is now saved on the LANGuardian system as a custom report and can be re-run any time updated information is needed.

The steps to create the report were as follows:
Click on Reports in the LANGuardian menu bar.
In the IP section, click on Traffic Distribution. LANGuardian displays the IP :: Traffic Distribution report.
Use the calender icon to specify both a start and end date.
Enter the IP address or subnet range for the VPN site in the IP/Subnet field.
Click View.
When LANGuardian displays the reports, click More Actions on the report menu bar and select Save Report.
Enter a name and description for the report, then click Save. The new report will be listed in the Custom Reports section.

If you have questions about monitoring VPN traffic, or any aspect of using LANGuardian, please contact us on any time.

Kind regards,
