Interface Sec Type This field indicates the type of security protections in
effect on the interface ([Public], [Private], or [DMZ]).
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.
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.
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],
as described in Configuring the ATM Virtual Circuit.
Config IP Address
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 ADSL
Barricade 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 [Enable], 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.
