3.4.3.9 Configuring Network Connections
The device supports various network connections, both physical and logical. The
Connections
item enables you to configure the various parameters of your physical
connections, the LAN and WAN, and create new connections, using tunneling protocols
over existing connections, such as PPP and VPN.
The logical network connections can be easily created using the Connection Wizard. This
wizard consists of a series of Web pages, intuitively structured to gather all the information
needed to create a logical connection.
Every network connection in the device can be configured as one of three types: WAN, LAN
or DMZ. For example, you may define that a LAN connection on the device operate as a
WAN network. This means that all hosts in this LAN are referred to as WAN computers,
both by computers outside the device and by the device itself. WAN and firewall rules may
be applied, such as on any other WAN network. Another example, is that a network
connection can be defined as a DMZ (Demilitarized) network. Although the network is
physically inside the device, it functions as an unsecured, independent network, for which
the device merely acts as a router.
Note:
When defining a network connection as a DMZ network:
•
Change the connection's routing mode to 'Route'.
•
Add a routing rule on your external gateway (which may be with your ISP)
informing of the DMZ network behind the device.

Point-to-Point Protocol over Ethernet (PPPoE):
relies on two widely accepted
standards, PPP and Ethernet. PPPoE enables your home network PCs that
communicate on an Ethernet network to exchange information with PCs on the
Internet. PPPoE supports the protocol layers and authentication widely used in PPP
and enables a point-to-point connection to be established in the normally multipoint
architecture of Ethernet. A discovery process in PPPoE determines the Ethernet MAC
address of the remote device in order to establish a session.
Ethernet connection:
configures the physical WAN Ethernet connection. It is the
most basic method intended for connections that do not require user name and
password to connect to the Internet.
