Using Diagnostic Tools & Restarting the SonicWALL Security Appliance
To 204.71.200.74 / 80 (02:00:cf:58:d3:6a)
The SonicWALL security appliance forwards the client ACK to the remote host and waits for the data
transfer to begin.
When using packet traces to isolate network connectivity problems, look for the location where the
three-way handshake is breaking down. This helps to determine if the problem resides with the
SonicWALL security appliance configuration, or if there is a problem on the Internet.
Select Packet Trace from the Diagnostic tool menu.
