Item Description
Ping or trace an IP
address
Ping – Used to send a ping packet request to a specified IP address—most often, to
test a connection. If the request times out (no reply is received), it usually means that
the destination is unreachable. However, some network devices can be configured
not to respond to a ping. The ping results will be displayed in a new screen; click
“Back” on the Windows menu bar to return to the Diagnostics screen.
If the specified address is intended to be reached through a VPN tunnel, check Ping
through VPN tunnel.
Traceroute – Lists all routers between the source (this device) and the destination IP
address. The traceroute results will be displayed in a new screen; click “Back” on the
Windows menu bar to return to the Diagnostics screen.
Perform a DNS
lookup
A DNS (Domain Name Server) converts the Internet name (for example,
www.netgear.com) to an IP address. If you need the IP address of a Web, FTP, Mail
or other Server on the Internet, you can request a DNS lookup to find the IP address.
Display the routing
table
This operation will display the internal routing table, which can be used by Technical
Support to diagnose routing problems.
Reboot the firewall Used to perform a remote reboot (restart). You can use this if the firewall seems to
have become unstable or is not operating normally.
Note: Rebooting will break any existing connections either to the firewall (such as
your management session) or through the firewall (for example, LAN users
accessing the Internet). However, connections to the Internet will automatically be re-
established when possible.
Packet trace Packet Trace selects the interface and starts the packet capture on that interface.
