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
"lower level" functions (i.e., closer to hardware) than the IPoA interface.
Peer IP Address:
The IP address of the remote computer you will be connecting to via the
WAN interface.
Config IP Address and Net Mask:
The IP address and network mask you want to assign to
the interface.
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 or with the remote peer computer.
5.7 Services
5.7.1 NAT
Network Address Translation
is a method for disguising the private IP addresses you
use on your LAN as the public IP address you use on the Internet. You define NAT rules that
specify exactly how and when to translate between public and private IP addresses.
