ATU-R140 ADSL Ethernet USB Router User's Guide

4.4.1 New Connection

A new connection is basically a virtual connection. Your gateway can support up to 8 different
(unique) virtual connections. If you have multiple different virtual connections, you may need
to utilize the static and dynamic routing capabilities of the modem to pass data correctly.
4.4.1.1 Bridged gateway profile and Connection
A pure bridged connection does not assign an IP address to the WAN interface. NAT and
firewall rules are not enabled. This connection method makes the Gateway act as a hub, and
just passes packets across the WAN interface to the LAN interface.
To configure the gateway as a bridge, from the Home page, click on Setup and then click on
New Connection. The default PPPoE connection setup is displayed. At the Type field select
Bridge and the Bridge connection setup page is displayed (see Figure 4). Give your Bridge
connection a unique name; the name must not have spaces and cannot begin with numbers.
In this case the unique name is called bridge1. Select the encapsulation type (LLC or VC); if
you are not sure just use the default mode. Select the VPI and VCI settings; your DSL service
provider or your ISP will supply these; in this case the DSL service provider is using 0,35.
Also select the quality of service (QOS); leave the default value if you are unsure or the ISP
did not provide this information.

To complete the connection you must now click the apply button. The apply button will
temporarily save this connection. To make the change permanent you need to click on Tools
(at the top of the page) and select System Commands. At the system commands page, click
on Save All.
4.4.1.2 PPPoA Connection Setup
PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM
cells which are carried over the DSL line. PPP or Point-to-Point protocol is a method of
establishing a network connection / session between network hosts. It usually provides a
mechanism of authenticating users. LLC and VC are two different methods of encapsulating
the PPP packet. Contact your ISP to make sure which encapsulation is being supported.
