Diagnostic Tools
The SonicWALL has several built-in tools which help troubleshoot network problems. Click
Tools on the left side of the browser window and then click the Diagnostic tab.
DNS Name Lookup
The SonicWALL has a DNS lookup tool that returns the numerical IP address of a domain
name or if you type in an IP address, it returns the domain name.
1. Select DNS Name Lookup from the Choose a diagnostic tool menu.
2. Enter the host name to lookup in the Look up the name field and click Go. Do not
add the prefix "http://". The SonicWALL then queries the DNS server and displays the
result at the bottom of the screen.
Note: You must define a DNS server IP address in the Network tab of the General
section to perform a DNS Name Lookup.
Find Network Path
The Find Network Path tool shows whether an IP host is located on the LAN, the WAN
or the DMZ. This is helpful to determine if the SonicWALL is properly configured. For
example, if the SonicWALL “thinks” that a machine on the Internet is located on the LAN
port, then the SonicWALL Network or Intranet settings can be misconfigured. Find
Network Path shows if the target device is behind a router, and the Ethernet address of
the target device. Find Network Path also shows the gateway the device is using and
helps isolate configuration problems.
