Ping
The Ping test bounces a packet off a machine on the Internet and returns it to the sender. This test shows if the SonicWALL security appliance is able to contact the remote host. If users on the LAN are having problems accessing services on the Internet, try pinging the DNS server, or another machine at the ISP location. If the test is unsuccessful, try pinging devices outside the ISP. If you can ping devices outside of the ISP, then the problem lies with the ISP connection.
1Select Ping from the Diagnostic Tool menu.
2Enter the IP address or host name of the target device and click Go.
3If the test is successful, the SonicWALL security appliance returns a message saying the IP address is alive and the time to return in milliseconds (ms).
Process Monitor
Process Monitor shows individual system processes, their CPU utilization, and their system time.
Reverse Name Resolution
The Reverse Name Resolution tool is similar to the DNS name lookup tool, except that it looks up a server name, given an IP address.
Enter an IP address in the Reverse Lookup the IP Address field, and it checks all DNS servers configured for your security appliance to resolve the IP address into a server name.
