6 Viewing System IP Information and
Performance Statistics
The interfaces on the VisionNet 202ER that communicate with other
network and Internet devices are identified by unique Internet
protocol (IP) addresses. You can use the Configuration Manager to
view the list of IP addresses that your device uses, and to view
other system and network performance data.
See Appendix A for a description of IP addresses and masks.
Viewing the VisionNet 202ER’s IP addresses
To view the VisionNet 202ER’s IP addresses, click IP Address in
the System Status tab. The IP Address Table page displays, as
shown in Figure 13:
Figure 13. IP Address Table Page
The table lists the IP addresses, network masks (“Net Mask”), and
interface names (“IF Name”) for each of its IP-enabled interfaces.
The listed IP addresses may include:
 The IP address of the device’s LAN (Ethernet) port, called
eth-0. See Chapter 5 for instructions on configuring this
address.
 The IP address of the WAN (ADSL line) interface, which
your ISP and other external devices use to identify your
network. It may be identified in the Configuration Manager
by the names ppp-0 or eoa-0, or ipoa-0, depending on the
protocol your device uses to communicate with your ISP.
Your ISP may assign the same address each time, or it
may change each time you reconnect.
 The “loopback” IP address, named lo-0, of 127.0.0.1. This
is a special address that enables the device to keep any
data addressed directly to it, rather than route the data
through the WAN or LAN ports.
If your device has additional IP-enabled interfaces, the IP
addresses of these will also display.
