You can configure the following settings on the PPP Configuration page:

Inactivity TimeOut...: The time in minutes that must elapse before a PPP connection

times-out due to inactivity. This setting applies only to PPP interfaces that are configured as

"start-on-data" interfaces. This type of interface starts up only when it receives data, and then

returns to a down state after the specified amount of time. This setting works with the following

setting to determine what type of data can activate a start-on-data interface.

Ignore WAN to LAN traffic...: When enabled, data traffic traveling in the incoming direction --

from a WAN interface to the LAN interface -- will not count as activity on the WAN port for the

purposes of determining whether to make it inactive; i.e., WAN to LAN traffic will not activate a

start-on-data interface. Only LAN-to-WAN traffic will start the interface.

The PPP Configuration table displays the following fields:

Interface: The predefined name of the PPP interface.

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 (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).

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
