Hurricane 9200/S ADSL Ethernet Router User’s Guide

The following table describes the fields on this page:
Field Description
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):
o 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.
o 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.
o 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 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 —the WAN port). This field should
reflect an interface name defined in the next lower
level of software over which the EoA interface will
operate. This will be an ATM VC interface, such as
aal5-0 .
Config IP Address
and Netmask
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
Hurricane 9200/S 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.
Use DHCP
When enabled, this setting instructs the device to
accept IP information assigned dynamically by your
ISP’s DHCP server. If the interface will be used for
bridging with your ISP and you will not be routing data
through it, leave this checkbox unselected.
Default Route
Indicates whether the Hurricane 9200/S uses the IP
address assigned to this interface, if any, as its default
route for your LAN. Your system can have only one
default route. See Chapter 10 for an explanation of
default routes.
Gateway Address
The external IP address that the ADSL/Ethernet
router communicates with via the EoA interface to
gain access to the Internet. This is typically an ISP
server.
