Viewing Your EOA Setup
To view your current EOA configuration, log into Configuration
Manager, click
Advanced
in the task bar, and then click
EOA
. Figure
40 shows the EOA Configuration page.
Figure 40. EOA Configuration Page
The EOA table contains a row for each EOA interface currently
defined on the device. The table may contain no entries if your ISP
does not use the EOA protocol.
The following table describes the fields on this page:
Field
Description
Interface
The name the software uses to identify the EOA
interface.
IPF Type
The type of IP Firewall protections in effect on the
interface (public, private, or DMZ):
o
A
public
interface connects to the Internet (IPoA
interfaces are typically public). Packets received
on a public interface are subject to the most
restrictive set of firewall protections defined in the
software.
o
A
private
interface connects to your LAN, such
as the Ethernet interface. Packets received on a
private interface are subject to a less restrictive
set of protections, because they originate within
the network.
o
The term
DMZ
(de-militarized zone), in Internet
networking terms, refers to computers that are
available for both public and in-network accesses
(such as a company's public Web server).
Packets incoming on a DMZ interface—whether
from a LAN or external source—are subject to a
level of protection that is in between those for
public and private interfaces.
Lower interface
EOA interfaces are defined in software, and then
associated with lower-level software and hardware
structures (at the lowest level, they are associated
with a physical port —the WAN port). This field should
reflect an interface name defined in the next lower
level of software over which the EOA interface will
operate. This will be an ATM VCC interface, such as
aal5-0
, as described in Chapter 12.
