Performing a DNS Lookup
You can use the Lookup tool to find out the IP address of host (for example, a Web,
FTP, or Mail server) on the Internet.
To retrieve the IP address of a Web, FTP, Mail or any other server on the Internet,
type the Internet Name in the text box and click Look up. If the host or domain
entry exists, you will see a response with the IP address. A message stating
"Unknown Host" indicates that the specified Internet Name does not exist.
To use the Lookup tool:
Choose Administration > Diagnostics > Network Tools.
In the Internet Name field, enter the Internet name of the host.
Click Look up.
The nslookup results appear.
Click Close when done.
Configuring Port Mirroring
Port mirroring monitors network traffic by sending copies of all incoming and
outgoing packets from one port to a monitoring port. You can use port mirroring as
a diagnostic or debugging tool, especially when fending off an attack or viewing
user traffic from LAN to WAN to see if users are accessing information or websites
they are not supposed to.
To configure port mirroring:
Choose Administration > Diagnostics > Port Mirroring.
In the Mirror Source area, check the ports to mirror.
In the Mirror Port area, choose a mirror port.
Click Save.
