IPoA Interface
: The name the software uses to identify the
IPoA interface
Config IP Address and Net Mask
: 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 device 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.
Interface Security Type
: The type of firewall protections
that are 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 public and private interfaces in
terms of restrictiveness.
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
: An IPoA interface must be associated
with one or more ATM VCs that have been defined on the
system. The ATM VC is also considered an interface--one
that performs "lower level" functions (i.e., closer to
hardware) than the IPoA interface. See Configuring the
ATM VC for information about ATM VC interfaces.
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.
