5.6.7EOA

This topic describes how to configure an Ethernet-over-ATM (EoA) interface on the ADSL/Ethernet router, if one is needed to communicate with your ISP. This interface is also commonly referred to as an RFC1483 interface, for the name of the Internet specification to which it conforms.

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):

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 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
