This topic describes how to configure an IPoA (Internet Protocol over ATM) interface on the ADSL/Ethernet router.

Interface: The name the software uses to identify the IPoA interface.

Interface Security Type: The type of firewall protections that are in effect on the interface (public, private, or DMZ):

zA 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.

zA 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.

zThe 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
