tcpdump: A LINUX program that can be used to monitor network traffic by inspecting tcp
packets. Default = ON.
If not needed, or wanted (out of concern for potential security risks), tcpdump can be dis-
abled permanently: Once toggled to OFF, and after executing a page reload, tcpdump
will be deleted from the system: The toggle switch will be removed, and the function can-
not be enabled again (even after a software upgrade).
iptables
While not accessible via the WebUI, iptables (an application allowing for customizable access
restrictions) have been supported since SecureSync Software Version 5.4.1.
Note that iptables is always ON, and its policies can only be accessed via the Command Line
Interface (see "CLICommands" on page513) in combination with the Sudo command. Please
also note that you need to have admin user rights to run this command.
Note: A listing of recommended and default network settings can be found under
"Default and Recommended Configurations" on page328.

1.

2.
The Ports panel displays the available Ethernet ports, and their connection status:
