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 .
Config IP Address
and Netmask The IP address and network mask you want to assign
to the interface. If the interface will be used for
bridging with your ISP and you will not be using the
Ethernet Modem Router as a router on your LAN,
then you do not need to specify IP information. If you
enable DHCP for this interface, then the Configured
IP address will serve only as a request to the DHCP
server. The actual address that is assigned by the
ISP may differ if this address is not available.
Use DHCP When enabled, this setting instructs the device to
accept IP information assigned dynamically by your
ISP’s DHCP server. If the interface will be used for
bridging with your ISP and you will not be routing data
through it, leave this checkbox unselected.
Default Route Indicates whether the Ethernet Modem Router uses
the IP address assigned to this interface, if any, as its
default route for your LAN. Your system can have
only one default route. See Chapter 10 for an
explanation of default routes.
Gateway Address The external IP address that the ADSL2+ Ethernet
Modem Router communicates with via the EoA
interface to gain access to the Internet. This is
typically an ISP server.
