The PPP{ XE "PPP:settings" } Configuration Table displays the following fields:
Field
Description
Interface
The predefined name of the PPP interface.
VCC
The Virtual Channel Connection over which this PPP
data is sent. The VCC identifies the physical path the
data takes to reach your ISP.
IPF Type
The type of IP 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 (PPoE) or PPP-over-ATM
(PPoA).
WAN IP
The IP address currently assigned to your WAN
(DSL) port by your ISP.
Gateway IP
The IP address of the server at your ISP that provides
you access to the Internet.
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.
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).
User 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.
When set to
Disable
, LAN hosts will use the DNS
address(es) preconfigured in the DHCP pool (see
“Configuring DHCP Server” on page 23)
Oper. Status
Indicates whether the link is currently up or down or if
a specific type of data exchange is under way (e.g.,
password authorization or DHCP).
