The Traceroute tool measures a network round-trip delay. Messages are sent per
hop and the wait occurs between each message. If the address is unreachable, it
uses the following formula to determine how long it takes for the Traceroute to
time out.
maximum hops (30) x the wait timeout (5) x 3 seconds
The Address Resolution Protocol (ARP) dynamically discovers the low-level
physical network hardware address that corresponds to the high-level IP address
for a host. ARP is limited to physical network systems that support broadcast
packets that are heard by all hosts on the network.

System configuration

Use the Admin > Config window to save the current or delete existing system
configuration files. Additionally, you can select one of the previously named
configurations and restore it as the current configuration.

File management

Use the Admin > File System > File System Maintenance window to navigate
through the VPN Router file system. This window lists the devices (drives) and
directories, which provides flexibility in viewing details of a file or directory and
allows you to delete unnecessary files. For example, if you have problems
performing an FTP transfer with a specific file, you can view the file details to
learn its file size and when it was last modified for troubleshooting purposes.
Additionally, you can toggle between hard drives when a backup drive is
available.
