NEOBIT 1014VA ADSL Router User’s Guide 
You can configure the following settings on the PPP Configuration 
page: 
 Inactivity Time Out (mins): The time in minutes that must 
elapse before a PPP connection times-out due to inactivity. 
 Ignore WAN to LAN traffic: When enabled, data traffic 
traveling in the incoming direction—from the WAN port to 
the LAN port—will not count as activity on the WAN port; 
i.e., it will not prevent the connection from being terminated 
if inactive for the specified time. 
 
The PPP 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. See Chapter 12 for 
more information. 
IPF Type 
The type of IP Firewall protections that are in effect on 
the interface (public, private, or DMZ): 
o
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. 
o
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. 
o
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. See “Hops and gateways” 
on page 84 for a description of gateway addresses. 
Default Route 
Indicates whether the ADSL Router should use the IP 
address assigned to this connection as its default 
route. Can be Enabled or Disabled. See  Chapter 10 
for an explanation of default routes.
