The following table describes the fields on this page:
Field Description
Interface The name the software uses to identify the IPoA
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.
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.
RFC 1577 Specifies whether the IPoA protocol to be used
complies with the IEFT specification named “RFC
1577 - Classical IP and ARP over ATM" (contact your
ISP if unsure).
Lower interface IPoA 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 IPoA interface
will operate. This will be an ATM VC interface, such
as aal5-0, as described in Chapter 0.
Peer IP Address The IP address of the remote computer you will be
connecting to via the WAN interface.
Config IP Address
and Netmask The IP address and network mask you want to assign
to the interface. If DHCP is enabled, this address
serves as a request to the remote computer’s DHCP
server, which may assign another address.
Gateway Address The external IP address that the ADSL/Ethernet router
communicates with via the IPoA interface to gain
access to the Internet. This is typically an ISP server.
Status A green or red ball will display to indicate that the
interface is currently up or down, respectively. You
cannot manually enable or disable the interface; a
down interface may indicate a problem with the DSL
connection.
Action Icons you can click on to edit ( ) or delete ( ) the
associated IPoA interface.
