30 Chapter 1 VPN Router administration

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.
