CHAPTER 1

Introducing the SBG3500-N Series

1.1 Overview

The SBG3500-N Series is a secure VPN (Virtual Private Network), multi-WAN gateway that provides

high-speed Internet access for business users. It features not only VDSL2/ADSL2+ Bonding

functionality, but also one Gigabit Ethernet (GbE) WAN with Small Form Factor Pluggable (SFP)

interface. SFP is also known as Fiber Optics interface. The GbE WAN with SFP is a dual-personality

design (GbE + Fiber) which enables increased bandwidth and extended coverage. Namely, the

SBG3500-N Series can adopt varied network environment and enable service providers to flexibly

install this device for VDSL, Fiber and 3G, in addition to provide load-balancing to ensure seamless

Internet connectivity.

FEATURES

• Four GbE Ports for LAN Connection

• One USB Port for 3G Connection and File Sharing

• One SFP Port for Fiber Optic Internet Connection

•One GbE WAN Port

• Two VDSL2/ADSL2+ (SBG3500-N000 only) Integrated Ports (Bonding)

• One VDSL2/ADSL2+ (SBG3500-NB00 only) Port

• Integrated Firewall with Secure Network Management

• IP secure VPN

Only use firmware for your SBG3500-N Series’s specific model. Refer to

the label on the bottom of your SBG3500-N Series.

Note: SFP and GbE connections cannot be used at the same time.

1.2 Applications for the SBG3500-N Series

Here are some example uses for which the SBG3500-N Series is well suited.

1.2.1 Internet Access

Your SBG3500-N Series provides multiple Internet access methods (up to two at a time), and you

can use them in the following combinations, if your ISP supports them.

Chapter 1 Introducing the SBG3500-N Series

SBG3500-N Series User’s Guide

• ADSL2+ and VDSL, connect the DSL1 and/or DSL2 port using a phone cable to a DSL or MODEM

on a splitter or your telephone jack. For single DSL connection, use only DSL1 port. For DSL

bonding connection, use both DSL1 and DSL2 port at the same time. Refer to Section 6.2 on

page 104 for the Network Setting > Broadband screen. When using the DSL1/DSL2 ports

and VDSL connection is not available, then the ADSL2+ will automatically be the network

interface. You need to enable bonding feature if you want to use the bonding state. See (Section

6.5 on page 119) for details.

• DSL and GbE, connect the DSL port to the DSL or MODEM as described above and connect the

GbE port to a broadband router (if available) using an Ethernet cable. The 3G USB dongle is the

failover or a backup connection in case both the DSL and GbE fails. You can set the load balance

and failover in SBG3500-N Series to prioritize and redirect all traffic to the backup connection in

case the Internet access is down by clicking Network Settings > Broadband > Multi-WAN

• DSL and Fiber (SFP), connect the the DSL port to the DSL or MODEM and connect the SFP port

using a Fiber Optical module, also known as a mini-GBIC transceiver, to a Switch or Router. The

3G USB dongle is the failover or backup connection. Set load balance as described above and see

the SBG3500-N Series’s Quick Start Guide for details on how to install and remove a mini-GBIC

transceiver.

• DSL and 3G, connect the DSL port to the DSL or MODEM and connect the USB port using a USB

3G dongle. The Fiber/Ethernet is the failover. You can set the load balance/failover as described

above.

• Fiber and 3G, connect the SFP port using a mini-GBIC transceiver and the USB port using a USB

3G dongle as described above. The DSL is the failover in case both Fiber and 3G is unavailable.

• GbE and 3G, connect the GbE port to a broadband router and the USB port using a USB 3G

dongle. The DSL is the failover in case both Fiber and 3G is unavailable.

• WLAN or Wireless Internet access, Refer to Section 1.2.2 on page 20 for more information.

The below table is a summary of the SBG3500-N Series Multi-WAN combinations and failover.

The following figure shows the possible internet access scenarios described above.

Computers can connect to the SBG3500-N Series’s LAN ports (or wirelessly).

You can also configure IP filtering on the SBG3500-N Series for secure Internet access. Go to

Security > MAC Filter to do this task. When the IP filter is on, all incoming traffic from the

Internet to your network is blocked by default unless it is initiated from your network. This means

that probes from the outside to your network are not allowed, but you can safely browse the

Internet and download files.

1.2.2 Wireless LAN

The SBG3500-N Series is a wireless Access Point (AP) for wireless clients, such as notebook

computers or PDAs and iPads. It allows them to connect to the Internet without having to rely on

inconvenient Ethernet cables.

You can configure your wireless network in either the built-in Web Configurator.
