Admin Overview
This section describes some of the concepts related to the
Admin
screens.
6.1.1
Debugging (Ping and Traceroute)
The CGN3 provides a couple of tools to allow you to perform network diagnostics on
the LAN:
Ping: this tool allows you to enter an IP address and see if a computer (or other
network device) responds with that address on the network. The name comes
from the pulse that submarine SONAR emits when scanning for underwater
objects, since the process is rather similar. You can use this tool to see if an IP
address is in use, or to discover if a device (whose IP address you know) is
working properly.

Traceroute: this tool allows you to see the route taken by data packets to get
from the CGN3 to the destination you specify. You can use this tool to solve
routing problems, or identify firewalls that may be blocking your access to a
computer or service.
