PPP Interface
: The predefined name of the PPP interface.
ATM VC
: The Virtual Circuit over which this PPP data is
sent. The VC identifies the physical path the data takes to
reach your ISP. See Configuring the ATM VC for more
information.
Interface Sec Type
: The type of Firewall protections that
are in effect on the interface (public, private, or DMZ): A
public interface connects to the Internet (PPP 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 set of
protections that is in between public and private interfaces
in terms of restrictiveness.
Protocol
: The type of PPP protocol used. Your ISP may
use PPP-over-Ethernet (PPPoE) or PPP-over-ATM
(PPPoA).
Default Route
: Indicates whether the ADSL/Ethernet router
should use the IP address assigned to this connection as
its default route. Can be Enabled or Disabled. See
Configuring IP Routes for an explanation of default routes.
MTU:
The Maximum Transmission Unit specifies the size in
bytes of the largest Ethernet packet that the interface will
accept. Packets larger than this size will be dropped.
Use DHCP
: When set to Enable, the device will acquire
additional IP information from the ISP's DHCP server. The
PPP connection itself acquires the device's IP address,
mask, DNS address, and default gateway address. With
Use DHCP enabled, the device will acquire IP addresses
for various other server types (WINS, SMTP, POP3, etc. --
these server types are listed on the DHCP Server
Configuration page).
Use DNS
: When set to Enable, the DNS address learned
through the PPP connection will be distributed to clients of
the device's DHCP server. This option is useful only when
the ADSL/Ethernet Router is configured to act as a DHCP
server for your LAN.
Security Protocol
: Select a security protocol and then
enter the user name and password.
