CHAPTER 1

Introducing the VMG

1.1 Overview

The VMG is a wireless VDSL router and Gigabit Ethernet gateway. The VMG works over the analog or

digital telephone system, POTS (Plain Old Telephone Service) and ISDN/T-ISDN.

• The VMG8825-B50B works over the analog telephone system, POTS (Plain Old Telephone Service).

• The VMG8825-B60B works over the digital telephone system, ISDN (Integrated Services Digital

Network) or T-ISDN (UR-2).

Only use firmware for your VMG’s specific model. Refer to the label on

the back of your VMG.

1.1.1 Internet Access

Your VMG provides shared Internet access by connecting the DSL port to the DSL or MODEM jack on a

splitter or your telephone jack. You can have multiple WAN services over one ADSL or VDSL. The VMG

cannot work in ADSL and VDSL mode at the same time.

Note: The ADSL and VDSL lines share the same WAN (layer-2) interfaces that you configure in

the VMG. Refer to Section 6.2 on page 75 for the Network Setting > Broadband screen.

Computers can connect to the VMG’s LAN ports (or wirelessly).

Figure 1 VMG’s Internet Access Application

You can also configure IP filtering on the VMG for secure Internet access. 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.

1.1.2 Ethernet WAN

If you prefer not to use a DSL line and you have another broadband modem or router (such as ADSL)

available, you can use the Ethernet WAN port and then connect it to the broadband modem or router.

This way, you can access the Internet via an Ethernet connection and still use the QoS, Firewall and

parental control functions on the VMG.

1.1.3 SFP

The VMG provides shared Internet access by connecting a Small Form-Factor Pluggable (SFP)

transceiver to the SFP port. In addition, you can connect computers, IPTVs, gaming consoles, and other

Ethernet devices to the Ethernet ports for fiber-speed Internet access.

1.1.4 WAN Priority

The WAN connection priority is as follows:

1 SFP

2 Ethernet WAN

3 DSL

4 Cellular WAN (3G/4G)

See Section 1.1.6 on page 18 for more information about Cellular backup.

1.1.5 Wireless Access

The VMG is a wireless Access Point (AP) for IEEE 802.11b/g/n/a/ac wireless clients, such as notebook

computers, iPands, smartphones, etc. These devices can connect to the VMG to access network

resources and the Internet.

Your VMG supports Wi-Fi Protected Setup (WPS), which allows you to quickly set up a wireless network

with strong security.

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

See Section 4.3 on page 39 for more information about how to set up a wireless network.

Figure 3 Wireless Access Example

1.1.6 VMG’s USB Support

The USB port of the VMG is used for cellular WAN backup, file-sharing and media server.

Cellular WAN (3G/4G) Backup

Connect a supported cellular USB dongle with an active SIM card to the USB port. This adds a second

WAN interface and allows the VMG to wirelessly access the Internet via a cellular network. The cellular

WAN connection is a backup in case the DSL connection fails.

To set up a cellular connection, click Network Setting > Broadband > Cellular Backup.

To update the supported cellular USB dongle list, download the latest WWAN package from the Zyxel

website and upload it to the VMG using the Maintenance > Firmware Upgrade screen.

File Sharing

Use the built-in USB 3.0 port to share files on a USB memory stick or a USB hard drive (B). Use FTP to access

the files on the USB device.

Figure 4 USB File Sharing Application

Media Server

You can also use the VMG as a media server. This lets anyone on your network play video, music, and

photos from a USB device (B) connected to the VMG’s USB port (without having to copy them to

another computer).

1.1.7 VoIP Features

You can register up to 2 SIP (Session Initiation Protocol) accounts and use the VMG to make and receive

VoIP telephone calls:

Figure 6 VMG’s VoIP Features

Calls via a VoIP service provider - the VMG sends your call to a VoIP service provider’s SIP server which

forwards your calls to either VoIP or PSTN phones.

1.2 Ways to Manage the VMG

Use any of the following methods to manage the VMG.

• Web Configurator. This is recommended for everyday management of the VMG using a (supported)

web browser.

• FTP. Use FTP for firmware upgrades and configuration backup/restore.

• SNMP (Simple Network Management Protocol). Use SNMP for exchanging management information

between network devices. See Chapter 36 on page 286 for more information about SNMP.
