DSL-500G ADSL Router User’s Guide
The PPP Configuration table displays the following fields:
PPP Interface
The PPP interface you are configuring.
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.
Interface Sec Type
The type of Firewall protections that are in effect on the interface.
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).
Protocol
The type of PPP protocol used. Your ISP may use PPP-over-Ethernet
(PPoE) or PPP-over-ATM (PPoA).
Service Name
This feature is available with PPoE interfaces but not with PPoA
interfaces. The name of the ISP service you are using with this PPP
connection. ISPs may offer different types of services (for example, for
online gaming or business communications), each requiring a different
login and other connection properties.
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.
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 Router is configured to act as a DHCP
Server for your LAN. When set to Disable, LAN hosts will use the DNS
address(es) pre-configured in the DHCP pool.
Default Route
This indicates whether the Router should use the IP address assigned to
this connection as its default route. It is Enabled by default and can be
Disabled by selecting the appropriate option.
Security Protocol
Protocol used to confirm the identity of the subscriber.
Login Name
The name you use to log in to your ISP each time this PPP connection is
established.
Login Password
The password you use to log in to your ISP each time this PPP connection
is established.
