Advanced
This chapter explains the Advanced Setup menu options outlined below.
8.1 WAN
This screen allows for the advanced configuration of WAN interfaces.
•
To Add a WAN connection, click the
Add
button. To edit an existing connection, click the Edit button next to the connection. To
complete the Add or Edit, on the opening screen, select VLAN Mux (see section 9.1.1VLAN Mux) and then proceed to STEP 2 in
section 4.2 Manual Quick Setup.
•
To remove a connection select its radio button under the Remove column in the table and click the
Remove
button under the table.
•
Save/Reboot
activates the new configuration.

8.1.1
VLAN Mux
VLAN Mux is a form of VLAN tagging that allows multiple protocols over a single connection.
Adding a new connection with VLAN Mux is accomplished by selecting the VLAN Mux – Enable Multiple Protocols Over a Single PVC check box
(as outlined in red below). Enter a value for 802.Q VLAN ID in the box that appears below.
After proceeding to STEP 3 in section 4.2 Manual Quick Setup, the screen will appear as follows. Notice that PPPoA and IPoA are not
available.
PVCs can be added using the regular procedure, however, now multiple protocols can exist over the same connection, as long as the
802.1Q VLAN IDs differ.

The graphic below shows an example of three protocols over the same connection.
8.1.2
MSP
Multi-Service over PVC (MSP) supports multiple protocols over a single connection. As with the VLAN Mux function, PPPoE, Bridge and
MER protocols can coexist, while IPoA and PPPoA are not supported. This function supports remote management by bridge protocol in
addition to multimedia applications over a single PVC.
Configuring MSP is a two-part process:
Part 1 -
Create multiple PVCs (One Bridge + multiple PPPoE / One MER)
Part 2 -
Use Port Mapping to connect LAN / WAN interfaces
NOTE:
The example below shows how to configure a Bridge / PPPoE MSP connection. Use the same process for
Bridge / MER MSP connections.
If QoS is configured on the first MSP connection, it will be configured by default for all subsequent connections.
If a MSP connection is removed every other MSP connection should be removed to avoid port mapping configuration problems.
Part 1 – Create Multiple PVCs
On the Advanced – WAN screen, create one PPPoE connection and one Bridge connection on the MSP supporting PVC. The screen will
display as follows.
Part 2
Go to Advanced – Port Mapping screen (see section 9.9 Port Mapping) and select the Enable Virtual Ports checkbox. The screen will
display as follows.
NOTE:
Only hardware ports and bridge PVCs are listed as interfaces. The bridge interface is shown as “nas_x_y_z” where x=port, y=vpi, and z=vci.
To continue, click the
Add
button at the bottom of the screen shown above.

On the screen shown below, select the bridge connection and one Ethernet virtual port (ENET 1-4). Enter a group name, such as “MSP1”,
and click
Save/Apply
.
If successfully configured, the Port Mapping screen will display as follows.

8.2 LAN
Use this screen to configure LAN interface settings.
NOTE:
NAT is enabled so Enable UPnP is shown above while DHCP Server Relay is hidden. Consult the field descriptions below for more details.
Field
Means
LAN IP Address
Default: 192.168.1.1. The LAN IP address of your NB9WMAXXn.
LAN Subnet Mask
Default: 255.255.255.0. The subnet mask of your NB9WMAXXn. A subnet mask is used to determine what subnet an IP address
belongs to. For more information on subnetting see http://www.ralphb.net/IPSubnet/.
Enable UPnP
Universal plug and play (UPnP) allows traffic to pass through the NB9WMAXXn for applications using the UPnP protocol. This
feature requires one active WAN connection. In addition, the client connecting to the NB9WMAXXn should support this feature.
UPnP also supports NAT Traversal which can automatically solve many NAT-related communications problems. UPnP enables
applications to assign dynamic port mappings to the NB9WMAXXn and delete them when connections are complete.
A typical example is the MSN Messenger application that runs on Windows. Instead of manually setting up the port mappings
UPnP enables
MSN Messenger to make the request to the NB9WMAXXn which will setup these ports dynamically. When MSN
Messenger is closed the port openings will be removed from the NB9WMAXXn’s configuration.
Configure the second IP address and subnet mask for LAN interface.
It is possible to configure the second IP address to access
the NB9WMAXXn on. Once this box is checked you are able to enter the IP address and subnet mask.
Disable DHCP Server
Disables the DHCP server.
Only to be done if Static IP address is set up.
Enable DHCP Server
Default: Enabled.
Start IP Address
Default: 192.168.1.2. The first IP address that will be issued to the first DHCP client connecting to the NB9WMAXXn using
Ethernet cable or wirelessly.
End IP Address
Default: 192.168.1.254. The last IP address in the DHCP pool to be issued to DHCP clients connecting to the NB9WMAXXn.
Lease Time
Default: 24 hours. The time an IP address is assigned to a client before being renewed.
Enable IGMP Snooping
IGMP specifies how a host can register a router in order to receive specific multicast traffic. IGMP Snooping allows the
NB9WMAXXn to capture IGMP frames. When your NB9WMAXXn hears an IGMP report from a host for a given multicast group
it adds the host’s port number for that group. When the NB9WMAXXn hears an IGMP Leave, it removes the host’s port from the
table entry.
Without IGMP snooping, multicast traffic is treated in the same manner as broadcast traffic - that is, it is forwarded to all ports.
With IGMP snooping, multicast traffic of a group is only forwarded to ports that have members of that group. IGMP Snooping
generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through your NB9WMAXXn.
Save
Save the settings.
Save / Reboot
Save and reboot with the settings applied.
NOTE:
The Save button saves new settings to allow continued configuration while the Save/Reboot button not only saves new settings but also reboots the device to apply
the new configuration (i.e. all new settings).

8.3 QoS Classification
Quality of Service (QoS) can provide different priority to different users or data flows, or guarantee a certain level of performance to a data
flow in accordance with requests from Queue Prioritization.
NOTE:
QoS must be enabled in at least one PVC to display this option. (see Advanced Setup - WAN for detailed PVC setup instructions).
8.3.1
Queue Management Configuration
To Enable QoS tick the checkbox, select Default DSCP Mark and click
Save/Apply
.
Select Default Differentiated Services Code Point (DSCP) Mark
With this drop-down box you can assign a DSCP mark in the Internet Protocol (IP) header that specifies the per hop behavior for a given
flow of incoming packets that do not match any other QoS rule.
8.3.2
Queue Configuration
This function follows the
Differentiated Services
rule of IP QoS. You can create a new Queue rule by assigning an Interface, Enable/
Disable and Precedence. The router uses various queuing strategies to tailor performance to user requirements
Click
Add
to display the following screen.
Field Name
Comment
Queue Configuration Status:
Enable or Disable the queue.
Queue:
Assign queue to a specific network interface whose QoS is enabled.
Queue Precedence:
Configure precedence for the queue. Lower integer values for precedence imply
higher priority for this queue relative to others.
