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): 

z

 

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. 

z

  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.   

z

 

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
