Using Ping
Ping is available on the System > Diagnostics page.
The Ping test bounces a packet off a machine on the Internet
and returns it to the sender. This test shows if the Dell
SonicWALL 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.
Using the Active Connections Monitor
The Active Connections Monitor displays real-time,
exportable (plain text or CSV), filterable views of all connections
to and through the Dell SonicWALL appliance. This tool is
available on the
Systems > Diagnostics page.
You can filter the results to display only connections matching
certain criteria. You can filter by
Source IP , Destination IP ,
Destination Port , Protocol , Src Interface and Dst Interface .
Enter your filter criteria in the Active Connections Monitor
Settings table.

string with a logical

Using Log > View
The Dell SonicWALL appliance maintains an Event log for
tracking potential security threats. You can view the log in the
Log > View page, or it can be automatically sent to an email
address for convenience and archiving. The log is displayed in
a table and can be sorted by column.
You can filter the results to display only event logs matching
certain criteria. You can filter by
Priority , Category ,
Source ( IP or Interface ), and Destination ( IP or Interface ).
