Chapter 1 Introduction
The VR-3031u is an 802.11n compliant Multi-DSL router that supports both ADSL2+ and
VDSL2. The latter is a brand new standard and technology perfect for triple play (Video,
Voice and Data) applications. The VR-3031u comes with four 10/100 Base-T Ethernet
ports, and one USB host, combining wired LAN connectivity and an integrated 802.11n
WiFi WLAN Access Point (AP) for wireless connectivity.
The VR-3031u is a cost effective solution designed to meet the needs of ISPs and carriers
planning on deploying a single DSL device for covering end users in different loop range areas.
Deploying VR-3031u is cost effective for ISPs and carriers because deploying a single CPE
DSL device with multiple profile support minimizes the number of required upgrades.

Chapter 3 Web User Interface
This section describes how to access the device via the web user interface (WUI)
using an Internet browser such as Internet Explorer (version 5.0 and later).
3.1 Default Settings
The factory default settings of this device are summarized below.
x LAN IP address: 192.168.1.1
x LAN subnet mask: 255.255.255.0
x Administrative access (username: root, password: 12345)
x User access (username: user, password: user)
x Remote (WAN) access (username: support, password: support)
x WLAN access: enabled
Technical Note
During power on, the device initializes all settings to default values. It will then
read the configuration profile from the permanent storage section of flash memory.
The default attributes are overwritten when identical attributes with different values
are configured. The configuration profile in permanent storage can be created via
the web user interface or telnet user interface, or other management protocols.
The factory default configuration can be restored either by pushing the reset button
for more than ten seconds until the power indicates LED blinking or by clicking the
Restore Default Configuration option in the Restore Settings screen.

WEP Encryption
g
This option specifies whether data sent over the network is encrypted. The same
network key is used for data encryption and network authentication. Four network
keys can be defined although only one can be used at any one time. Use the Current
Network Key list box to select the appropriate network key.
Security options include authentication and encryption services based on the wired
equivalent privacy (WEP) algorithm. WEP is a set of security services used to
protect 802.11 networks from unauthorized access, such as eavesdropping; in this
case, the capture of wireless network traffic.
When data encryption is enabled, secret shared encryption keys are generated and
used by the source station and the destination station to alter frame bits, thus
avoiding disclosure to eavesdroppers.
Under shared key authentication, each wireless station is assumed to have received
a secret shared key over a secure channel that is independent from the 802.11
wireless network communications channel.
Encryption Strength
This drop-down list box will display when WEP Encryption is enabled. The key
strength is proportional to the number of binary bits comprising the key. This
means that keys with a greater number of bits have a greater degree of security and
are considerably more difficult to crack. Encryption strength can be set to either
64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10
hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26
hexadecimal numbers. Each key contains a 24-bit header (an initiation vector)
which enables parallel decodin
of multiple streams of encrypted data.

Auto Detection notice
Note: The following description concerning ETHWAN is for multiple LAN port devices
only.
1) This feature will automatically detect one WAN service only. If customers require
multiple WAN services, manual configuration is required.
2) If a physical ETHWAN port is detected, the Auto Detection for ETHWAN will be
fixed on the physical ETHWAN port and cannot be configured for any LAN port;
if the physical ETHWAN port is not detected, the Auto Detection for ETHWAN will
be configured to the 4
th
LAN port by default and allows it to be configured for any
LAN port as well.
3) For cases in which both the DSL port and ETHWAN port are plugged in at the
same time, the DSL WAN will have priority over ETHWAN. For example, the
ETHWAN port is plugged in with a WAN service detected automatically and then
the DSL port is plugged in and linked up. The Auto Detection feature will clear
the WAN service for ETHWAN and re-detect the WAN service for DSL port.
4) If none of the pre-configured services are detected, a Bridge service will be
created.

6.9 Interface Grouping
Interface Grouping supports multiple ports to PVC and bridging groups. Each group
performs as an independent network. To use this feature, you must create mapping
groups with appropriate LAN and WAN interfaces using the Add button.
The Remove button removes mapping groups, returning the ungrouped interfaces
to the Default group. Only the default group has an IP interface.
To add an Interface Group, click the Add button. The following screen will appear.
It lists the available and grouped interfaces. Follow the instructions shown
onscreen.

Automatically Add Clients With Following DHCP Vendor IDs:
Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID
(option 60). The local DHCP server will decline and send the requests to a remote
DHCP server by mapping the appropriate LAN interface. This will be turned on when
Interface Grouping is enabled.
For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is
for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are
ENET1, ENET2, ENET3, and ENET4.
The Interface Grouping configuration will be:
94
Page 96
1. Default: ENET1, ENET2, ENET3, and ENET4.
2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video".
If the onboard DHCP server is running on "Default" and the remote DHCP server is
running on PVC 0/36 (i.e. for set-top box use only). LAN side clients can get IP
addresses from the CPE's DHCP server and access the Internet via PPPoE (0/33).
If a set-top box is connected to ENET1 and sends a DHCP request with vendor ID
"Video", the local DHCP server will forward this request to the remote DHCP server.
The Interface Grouping configuration will automatically change to the following:
1. Default: ENET2, ENET3, and ENET4
2. Video: nas_0_36, nas_0_37, nas_0_38, and ENET1.
