Configuring EOA Interfaces
This chapter describes how to configure an Ethernet-over-ATM interface on the Best Data
DSL542, if one is needed to communicate with your ISP.
Viewing Your EOA Setup
To view your current EOA configuration, log into Configuration Manager, click
EOA
task bar, and then click
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:

Description
The name the software uses to identify the EOA
interface.
The type of IP Firewall protections in effect on the
interface (public, private, or DMZ):
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.
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.
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.
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.
