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 52 shows the EOA Configuration page.
Figure 52. 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.
Interface Sec Type The type of security 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 VC interface, such
as aal5-0, as described in Chapter 0.
